Mexico City is often associated with warm Mexican weather, leading many travelers to assume that summer clothing will be enough throughout the year. However, the climate in Mexico City is noticeably different from that of coastal destinations such as Cancun and Los Cabos.
Located more than 2,200 meters above sea level, Mexico City has mild daytime temperatures, cool mornings, and noticeably cooler evenings. Even after a warm afternoon, temperatures can fall quickly once the sun goes down.
During the dry season, the difference between daytime and nighttime temperatures can be significant. During the rainy season, a bright morning can be followed by a heavy afternoon shower. It is entirely possible to need a short-sleeved shirt, a light jacket, and an umbrella on the same day.
Understanding Mexico City weather by month therefore requires more than checking whether the season is spring, summer, autumn, or winter. It is equally important to understand the differences between the dry and rainy seasons.
This guide covers monthly temperatures, rainfall patterns, recommended clothing, weather-related precautions, and the best time to visit Mexico City.
Understanding Mexico City’s Climate
Mexico City has a relatively mild climate throughout the year. Average daytime highs usually remain between approximately 20°C and 26°C, while average nighttime lows generally range from around 7°C to 13°C.
These temperatures may appear comfortable, but the daily temperature range can feel surprisingly large. A short-sleeved shirt may be comfortable at midday, while a jacket may be necessary early in the morning or after sunset.
The city’s climate can generally be divided into two main periods: the dry season and the rainy season.
Mexico City Dry Season
The dry season usually runs from November through April. Rainfall is relatively limited, and clear or sunny days are common.
This is a convenient time for walking tours, outdoor attractions, and day trips to archaeological sites such as Teotihuacan. However, dry weather can also mean lower humidity, dry skin, and strong sunshine during the day.
Travelers visiting during the dry season should pack lip balm, moisturizer, sunscreen, and clothing that can be worn in layers. A light jacket is particularly useful for early morning departures and evening activities.
Mexico City Rainy Season
Rainfall begins to increase in May, while June through September is generally considered the main rainy season. Rain gradually becomes less frequent during October as the city transitions back into the dry season.
The rainy season does not usually mean continuous rain from morning until night. Many days begin with relatively clear or partly cloudy conditions before showers and thunderstorms develop during the afternoon or evening.
Heavy rain can temporarily flood roads and cause traffic delays. During the rainy season, it is practical to schedule outdoor attractions in the morning and reserve museums, galleries, cafés, shopping centers, and other indoor activities for later in the day.

These figures are approximate long-term averages. Actual temperatures and rainfall can vary by year, neighborhood, elevation, and weather system. Check the short-term forecast 7 to 10 days before departure, then check it again immediately before your trip.
Mexico City Weather in January
January is one of the coolest months in Mexico City. Daytime temperatures usually rise to approximately 20°C, making sunny afternoons feel pleasant. Early morning temperatures, however, can fall to around 7°C.
Rainfall is limited, so January is generally convenient for sightseeing. The main challenge is the large difference between daytime and nighttime temperatures.
A long-sleeved shirt and trousers are usually comfortable during the day. For early morning tours or evening activities, add a knit sweater, medium-weight jacket, or packable insulated jacket.
Travelers who are sensitive to cold should not rely only on light summer clothing. The air can feel especially cool in shaded areas, before sunrise, and after sunset.
Dry air may also cause discomfort for travelers with sensitive skin or eyes. Lip balm, moisturizer, and personal eye drops can be useful additions to a January packing list.
Air quality may occasionally be less comfortable when weather conditions limit air circulation. Check both the weather forecast and local air-quality information before planning long periods of outdoor activity.
Mexico City Weather in February
February remains dry, but daytime temperatures begin to rise. Average afternoon highs can reach approximately 22°C to 23°C, while mornings may still begin with single-digit temperatures.
Clear skies and limited rainfall make February a good month for walking tours, outdoor attractions, and day trips. The sun can feel warm at midday, but shaded streets and breezy areas may remain cool.
Pack thin long-sleeved tops, comfortable trousers, and a lightweight jacket or cardigan. Choose an outer layer that is easy to carry once the temperature rises.
Because the air remains relatively dry, travelers may benefit from carrying lip balm, moisturizer, water, and any personal products needed to reduce dryness.
Sunscreen is also important. Comfortable air temperatures should not be mistaken for weak sunlight, particularly at Mexico City’s high elevation.
Mexico City Weather in March
March is one of the most attractive months for visiting Mexico City. Average daytime highs reach approximately 24°C, while humidity generally remains lower than during the rainy season.
Limited rainfall makes it easier to plan visits to the Historic Center, Chapultepec Park, Coyoacán, Xochimilco, and Teotihuacan. Depending on annual conditions, travelers may also see jacaranda trees blooming across parts of the city.
During the afternoon, a T-shirt or lightweight shirt may be enough. Early mornings and evenings can still feel cool, so pack a cardigan, overshirt, or light jacket.
Sunshine and ultraviolet exposure can feel strong in March. Apply sunscreen before leaving your accommodation, wear sunglasses, and consider using a wide-brimmed hat for long outdoor visits.
When arranging a full day of sightseeing, include occasional breaks in shaded areas. Travelers planning an archaeological day trip should carry water and sun protection because exposed sites may have limited shade.
Mexico City Weather in April
April is one of the warmest months during the daytime. Average highs can reach approximately 25°C to 26°C, and direct sunlight may make exposed areas feel warmer.
Rain is generally limited, although isolated showers can become more likely toward the end of the month. Mornings remain relatively cool, afternoons are warm, and evenings can become comfortable or slightly cool.
Short-sleeved tops, lightweight shirts, and breathable trousers are practical during the day. A thin long-sleeved shirt can provide additional protection from strong sunlight.
Pack a light outer layer if you plan to visit rooftop restaurants, attend evening events, or return to your accommodation late at night.
Semana Santa and Easter travel periods may affect accommodation availability, transportation, and popular attractions. Compare cancellation conditions and total booking prices early if your trip overlaps with these dates.
Mexico City Weather in May
May is another warm month, with average daytime highs of approximately 25°C. On clear days, direct sunlight can make it feel hotter than the recorded temperature suggests.
May is also a transition month between the dry and rainy seasons. Early May may still feel relatively dry, while afternoon showers and thunderstorms become more common as the month progresses.
Wear short-sleeved tops and breathable trousers during the warmest part of the day. Carry a thin shirt or cardigan for air-conditioned indoor spaces and cooler evenings.
A compact umbrella or lightweight rain jacket becomes increasingly useful. Weather can change quickly in the afternoon, so check the hourly forecast rather than relying only on the daily weather symbol.
Before a thunderstorm, winds may become stronger and temperatures can drop suddenly. If you have an afternoon outdoor tour, check the weather shortly before departure and review the operator’s cancellation or rescheduling policy.
Mexico City Weather in June
June generally marks the beginning of the main rainy season. Average daytime highs are around 23°C, while nighttime or early morning temperatures are approximately 13°C.
Temperatures are usually lower than in April or May, but humidity and rainfall increase. A common pattern is a relatively bright morning followed by heavy showers or thunderstorms during the afternoon or evening.
Pack lightweight, quick-drying clothing and a breathable rain jacket. An umbrella alone may be inconvenient during windy thunderstorms, so carrying both a compact umbrella and a waterproof outer layer is practical.
Outdoor attractions such as Teotihuacan and Xochimilco are better scheduled for the morning when possible. Indoor attractions, including the National Museum of Anthropology and major art museums, can be placed later in the day.
Heavy rain may slow road traffic. Avoid arranging tightly connected activities on opposite sides of the city, especially during the late afternoon.
Mexico City Weather in July
July is a rainy and relatively mild month. Average daytime highs are approximately 21°C to 22°C, while average lows remain close to 12°C.
Cloud cover and rain can make the weather feel cooler than expected. A short-sleeved shirt may be comfortable during brighter periods, but wet clothing combined with wind can quickly feel cold.
Wear a light top underneath a waterproof or water-resistant jacket. Quick-drying trousers and comfortable walking shoes with reliable traction are preferable to clothing that stays wet for a long time.
Cheap disposable rain ponchos may provide temporary protection, but they can become uncomfortable during extended walking. A lightweight breathable jacket is a better option for travelers spending several hours outdoors.
Road congestion may intensify after heavy rain. Allow at least 30 additional minutes for airport transfers, performances, restaurant reservations, and other time-sensitive plans. More extra time may be necessary during rush hour.
Mexico City Weather in August
August remains within the rainy season. Average daytime highs are around 22°C, and nighttime lows are approximately 12°C.
Rain is more likely in the afternoon than early in the morning, although weather patterns can vary. Travelers who begin sightseeing early may find several useful hours for outdoor activities before clouds develop.
Pack breathable clothing, a thin waterproof jacket, and a compact umbrella. Shoes should be comfortable for long walks and provide traction on wet pavement.
Completely waterproof footwear is not always necessary. Heavy rain boots can become uncomfortable during extended sightseeing. Lightweight walking shoes that provide grip and dry reasonably quickly may be more practical.
Weather-sensitive activities such as boat rides in Xochimilco or extended park visits should have a backup plan. Museums, markets, cafés, and shopping centers can serve as alternatives during heavy rain.
Mexico City Weather in September
September is often one of the wettest periods of the year in Mexico City. Average daytime highs are close to 21°C, with nighttime lows of approximately 12°C.
Temperatures remain mild, but frequent rain can make the weather feel cooler. Some days may start cloudy, and showers are not always limited to the late afternoon.
Thunderstorms can bring heavy downpours, temporary road flooding, and significant traffic delays. A light rain jacket, compact umbrella, long trousers, and shoes with good traction are recommended.
Light-colored trousers and water-sensitive shoes may become dirty quickly on wet streets. Darker colors and easy-care materials are generally more practical.
Mexican Independence Day celebrations take place around September 15 and 16. Events, crowds, road closures, and transportation changes can affect movement through central areas. Check local traffic conditions along with the weather forecast when arranging your itinerary.
Mexico City Weather in October
October is a transition period between the rainy and dry seasons. Afternoon showers may continue early in the month, while clearer and drier conditions become more common toward the end.
Average daytime highs are approximately 21°C, and average lows are close to 11°C. Mornings and evenings feel cool, while midday temperatures are usually comfortable for walking.
Wear a short-sleeved or thin long-sleeved top under a cardigan or light jacket. A compact umbrella remains useful, particularly for trips during the first half of the month.
October offers a favorable balance between temperature and sightseeing conditions. This makes it one of the more convenient months for first-time visitors who want to combine outdoor landmarks, neighborhoods, parks, museums, and food experiences.
Even when the day begins with clear skies, check the hourly forecast before leaving for a long outdoor excursion.
Mexico City Weather in November
November marks the return of drier conditions. Average daytime highs are approximately 20°C to 21°C, while morning temperatures may fall to around 9°C.
Clear days and limited rainfall make November suitable for walking through the Historic Center, visiting Chapultepec Park, exploring Coyoacán, or taking a day trip to Teotihuacan.
Pack long-sleeved shirts, trousers, and a cardigan or lightweight jacket. Travelers joining an early morning excursion may also appreciate a thin sweater or wind-resistant outer layer.
Día de Muertos events and displays around the beginning of November can attract large crowds to popular neighborhoods and public spaces. Accommodation location and transportation access become particularly important during this period.
November is often one of the best times to visit Mexico City for travelers who prioritize comfortable daytime temperatures and a lower chance of rain.
Mexico City Weather in December
December is usually clear and dry. Average daytime highs remain close to 20°C, while early morning temperatures can fall to approximately 8°C.
The afternoon may feel pleasantly warm in direct sunlight, but evenings require warmer clothing. Some indoor spaces may also feel cooler than expected, so travelers should avoid packing only lightweight sleepwear.
Long-sleeved tops, trousers, knitwear, and a medium-weight jacket form a practical December wardrobe. A warmer outer layer is useful for nighttime events, rooftop venues, and early morning departures.
Christmas and New Year travel demand may increase flight and accommodation prices. Popular restaurants, tours, and events may also reach capacity earlier than usual.
Once your travel dates are confirmed, consider reserving accommodation with a flexible cancellation policy. This can secure a suitable location while allowing you to monitor prices or adjust your plans if necessary.
Best Time to Visit Mexico City
The best time to visit Mexico City depends on your preferred activities, tolerance for rain, budget, and interest in seasonal events.
Best Months for Comfortable Weather
March, April, October, and November provide a favorable balance between mild temperatures and manageable rainfall.
March and November are especially suitable for first-time visitors. Conditions are generally comfortable for walking, and the risk of repeated heavy afternoon rain is lower than during the main rainy season.
April can be warmer during the day, while early October may still receive some afternoon rain. Travelers should select a month based on whether warmth or a lower chance of rain is more important.
Best Time to Avoid Rain
Travelers who want to minimize rainfall should consider visiting between November and April.
The dry season generally provides more predictable conditions for outdoor sightseeing and day trips. However, mornings and evenings can be much cooler than daytime temperatures suggest.
Pack a jacket, sunscreen, lip balm, and moisturizer. Strong sunshine and dry air can be noticeable even when daytime temperatures feel mild.
Best Time for Fewer Weather-Related Crowds
Some rainy-season weekdays may feel less crowded than major dry-season holiday periods. However, rainy-season flights and hotels are not automatically cheaper.
Prices depend on the exact dates, day of the week, major events, booking lead time, and accommodation demand. Compare actual rates rather than assuming that every rainy-season trip will be inexpensive.
If visiting between June and September, avoid placing every expensive or non-refundable outdoor activity at the beginning of the trip. Keeping some flexibility allows you to choose the clearest day for weather-sensitive tours.
What to Pack for Mexico City
Your packing list should reflect the daily temperature range rather than only the average afternoon temperature.
Recommended items include:
- Short-sleeved and thin long-sleeved tops
- Cardigan, windbreaker, or light jacket
- Knitwear or a packable insulated jacket for winter mornings
- Comfortable walking shoes
- Shoes with reliable traction for wet pavement
- Sunscreen
- Wide-brimmed hat or cap
- Sunglasses
- Compact umbrella
- Lightweight waterproof jacket
- Lip balm and moisturizer
- Reusable water bottle
- Secure zippered day bag
- Waterproof pouch for a wet umbrella or damp clothing
Layering is more useful than packing one very heavy coat. A short-sleeved top, overshirt, cardigan, and jacket can be combined in different ways as temperatures change throughout the day.
Weather Conditions to Watch in Mexico City
Large Day-to-Night Temperature Changes
The daily temperature range can be significant, particularly during the dry season. Packing only for the afternoon temperature may leave you unprepared for an early morning tour or late evening return.
Carry a light outer layer even when the daytime forecast looks warm.
Strong Sunshine and UV Exposure
Mexico City’s elevation can make sunlight feel strong even when air temperatures are moderate.
Use sunscreen, wear sunglasses, and consider a hat for extended outdoor activities. Sun protection remains useful on partly cloudy days.
Heavy Rain and Thunderstorms
From June through September, short but intense downpours may occur. Thunderstorms are most common during the afternoon and evening, although rain can develop at other times.
If the rain becomes severe, waiting inside a building may be safer and more comfortable than attempting to continue walking.
Temporary Flooding and Traffic Delays
Heavy rain can produce temporary standing water and worsen traffic congestion.
Allow additional travel time when going to the airport, bus terminal, reserved performance, restaurant, or timed-entry attraction. Avoid scheduling important reservations too close together during rainy-season afternoons.
High-Altitude Conditions
Some visitors may feel unusually tired or short of breath after arriving in Mexico City.
Keep your first day relatively light, drink water regularly, and avoid scheduling an intense walking tour or strenuous exercise immediately after arrival.
If symptoms are severe, unusual, or persistent, stop the activity and seek assistance from an appropriate local medical provider.
Mexico City Weather and Clothing Summary
The most important factors in Mexico City weather by month are rainfall and the difference between daytime and nighttime temperatures.
November through April is generally dry, with many clear days suitable for sightseeing. Travelers should still prepare for cool mornings, strong sunshine, and dry air.
Rain begins to increase in May. June through September is the main rainy season, when afternoon and evening showers are common. During these months, schedule outdoor activities in the morning and keep indoor alternatives available for later in the day.
Rain usually decreases during October, and dry weather becomes more established in November. First-time visitors seeking a balance of comfortable temperatures and manageable rainfall may prefer March, April, October, or November.
After choosing your travel dates, check the local forecast 7 to 10 days before departure and again immediately before leaving. Matching your clothing and daily itinerary to the expected conditions can reduce weather-related schedule changes and unnecessary purchases during the trip.
