Planning a trip to New Orleans involves more than choosing a hotel and making a list of restaurants. Weather can have a major impact on how comfortable your trip will be, especially if you plan to explore the French Quarter, walk through the Garden District, or join outdoor tours.
Winters in New Orleans are generally mild, but sudden cold fronts can make mornings and evenings much cooler than expected. Summers are long, hot, and extremely humid. Even when the temperature does not look unusually high, the humidity can make it feel several degrees warmer.
Checking New Orleans weather by month before booking your trip can help you choose the best travel dates, pack the right clothing, and avoid scheduling too many outdoor activities during uncomfortable weather.
This guide covers seasonal conditions, average monthly temperatures, rainfall, weather hazards, and what to wear in New Orleans from January through December.
New Orleans Climate Overview
New Orleans has a humid subtropical climate characterized by long, hot summers and short, relatively mild winters.
Summer daytime temperatures commonly reach 90°F to 92°F, or approximately 32°C to 33°C. Overnight temperatures often remain around 75°F to 77°F, or 24°C to 25°C.
High humidity can make summer temperatures feel considerably hotter. Afternoon showers and thunderstorms are also common from June through September. Rain may be brief, but it can become intense enough to leave standing water on streets and sidewalks.
Winter temperatures are much milder than those in many northern U.S. cities. Daytime temperatures usually reach the low to mid-60s Fahrenheit, or approximately 17°C to 19°C. However, cold fronts can cause temperatures to fall quickly, particularly at night.
Rain is possible throughout the year. Travelers should prepare for a mixture of sunshine, clouds, and occasional heavy rain rather than expecting a clearly defined dry season.

New Orleans Weather in January
January is typically the coolest month in New Orleans. Average temperatures range from approximately 46°F to 63°F, or 8°C to 17°C.
Afternoons can feel pleasantly mild when the sun is shining, but temperatures often drop quickly after sunset. Travelers planning evening jazz performances, ghost tours, or late dinners in the French Quarter should not rely on the daytime temperature when deciding what to wear.
Pack long-sleeved shirts, sweaters, long pants, and a wind-resistant jacket. A lightweight insulated jacket can be useful for travelers who are sensitive to cold.
The main weather concerns in January are cold fronts, chilly rain, and strong winds. Humidity can also make cool temperatures feel colder than the thermometer suggests.
New Orleans Weather in February
February temperatures generally range from 50°F to 66°F, or 10°C to 19°C. Some days can feel like early spring, while others remain cool and damp.
February is an important month for Carnival celebrations and Mardi Gras activities. Visitors may spend several hours standing or walking outside, and temperatures can change noticeably between the afternoon and evening.
Layering is the most practical approach. Wear a short-sleeved or lightweight long-sleeved top under a sweater or light jacket. Bring comfortable shoes that can handle wet pavement.
Rapid weather changes are the main concern. Check the hourly forecast on parade or event days because conditions may be very different in the evening than they were earlier in the day.
New Orleans Weather in March
March brings warmer spring weather, with average temperatures between 55°F and 72°F, or 13°C and 22°C.
This is a comfortable month for exploring the French Quarter, walking through the Garden District, visiting City Park, or spending time along the Mississippi River. Mornings and evenings can still feel cool, especially after a cold front.
A short-sleeved shirt, a light button-down shirt, and a thin jacket provide enough flexibility for most days. Comfortable walking shoes are essential because many popular neighborhoods have uneven sidewalks.
The primary weather concerns are temperature swings, strong wind, and occasional thunderstorms. A compact umbrella or lightweight rain jacket is useful even if the morning forecast looks clear.
New Orleans Weather in April
April is one of the most popular months to visit New Orleans. Average temperatures range from approximately 63°F to 78°F, or 17°C to 26°C.
The weather is usually warm without the extreme summer humidity. This makes April suitable for outdoor festivals, walking tours, riverfront visits, and day trips outside the city.
Wear short sleeves, lightweight pants, or other breathable clothing. A light cardigan can be helpful in air-conditioned venues or during cooler evenings. Sunscreen, sunglasses, and a hat are also recommended.
Heavy showers and thunderstorms can occur. If thunder is audible, move indoors rather than sheltering under trees or exposed structures. Outdoor event schedules may also change because of lightning.
New Orleans Weather in May
May feels more like early summer than late spring. Average temperatures range from 70°F to 85°F, or 21°C to 30°C.
Heat and humidity become increasingly noticeable during the month. Walking for several hours in the afternoon may feel tiring, particularly for children, older travelers, and visitors who are not accustomed to humid conditions.
Plan outdoor sightseeing for the morning whenever possible. Museums, restaurants, and other air-conditioned attractions can be scheduled during the hottest part of the afternoon.
Pack breathable short-sleeved shirts, lightweight pants or shorts, comfortable footwear, sunscreen, and a hat. A thin long-sleeved shirt is helpful inside heavily air-conditioned buildings.
The main concerns are heat, humidity, and afternoon thunderstorms. Drink water regularly rather than waiting until you feel thirsty.
New Orleans Weather in June
June marks the beginning of the most consistently hot and humid period. Average temperatures range from approximately 75°F to 89°F, or 24°C to 32°C.
Rainfall is relatively high, and afternoon thunderstorms can develop quickly. A storm may last only a short time, but intense rain can leave water on roads and sidewalks.
Wear moisture-wicking shirts, lightweight bottoms, and comfortable shoes that will not be damaged easily if they get wet. Carry a compact umbrella or packable rain jacket.
June also falls within the Atlantic hurricane season. Although the highest tropical storm risk usually occurs later in the season, travel disruption is still possible.
Choose hotels, flights, and tours with practical cancellation or change policies. Avoid building an itinerary in which every activity depends on clear weather.
New Orleans Weather in July
July is one of the hottest months in New Orleans. Average temperatures range from 77°F to 91°F, or 25°C to 33°C.
High humidity can push the heat index well above the measured air temperature. Evenings remain warm, so travelers may get little relief from the heat after sunset.
Wear lightweight, quick-drying clothing, a breathable hat, sunglasses, and sunscreen. Carry water and take regular breaks in air-conditioned spaces.
Avoid scheduling long outdoor walks during the hottest part of the day. A practical plan is to explore outside in the morning, have a long indoor break during the afternoon, and return to outdoor areas in the evening.
The primary concerns are heat exhaustion, heat-related illness, thunderstorms, and lightning. Headache, dizziness, nausea, weakness, or confusion can be signs that immediate cooling and rest are necessary.
New Orleans Weather in August
August remains extremely hot and humid, with average temperatures between 77°F and 91°F, or 25°C and 33°C.
Warm nights and high humidity can make this month physically demanding. Afternoon thunderstorms are common, and heavy rain may cause temporary street flooding.
Pack quick-drying summer clothing, waterproof or water-resistant shoes, a compact umbrella, and at least one change of clothes. A thin shirt or cardigan can be useful inside cold, air-conditioned restaurants and museums.
Never walk or drive through deep or moving floodwater. Water depth can be difficult to judge, and flooded areas may conceal damaged pavement or other hazards.
August also brings a higher risk of tropical weather. Review airline, hotel, and tour cancellation policies before completing nonrefundable reservations.
New Orleans Weather in September
September temperatures generally range from 73°F to 88°F, or 23°C to 31°C. Despite the beginning of fall on the calendar, the weather still feels like summer.
Early September can be nearly as hot as July and August. Humidity remains high, and strong thunderstorms are possible.
Lightweight summer clothing, rain protection, comfortable water-resistant shoes, and an extra shirt are useful. Travelers should continue to protect themselves from heat and strong sunlight.
September is an important month for monitoring hurricanes and tropical storms. Severe weather can lead to flight cancellations, tour suspensions, road closures, power disruptions, and changes in hotel operations.
Check both the regular forecast and active tropical weather information before departure. Flexible reservations are particularly valuable during this period.
New Orleans Weather in October
October is frequently considered one of the best months to visit New Orleans. Average temperatures range from approximately 64°F to 81°F, or 18°C to 27°C.
The beginning of the month may still feel hot, but humidity generally decreases as October progresses. Walking tours and outdoor dining become more comfortable than they are during summer.
Short sleeves are suitable during many afternoons. Bring a light long-sleeved shirt or cardigan for mornings, evenings, and air-conditioned buildings.
Late-season heat and large differences between daytime and nighttime temperatures are the main concerns. October also remains within the official hurricane season, so tropical weather cannot be ruled out completely.
New Orleans Weather in November
November offers some of the most comfortable sightseeing conditions of the year. Average temperatures range from 54°F to 72°F, or 12°C to 22°C.
Lower humidity makes it easier to spend several hours walking outdoors. November can be especially suitable for exploring architecture, parks, historic neighborhoods, and riverfront areas.
Pack long-sleeved shirts, long pants, a lightweight sweater, and a jacket. Wear layers that can be removed when the afternoon becomes warmer.
Cold fronts can bring sudden temperature drops and chilly rain. Check the wind speed and evening temperature if you plan to take a night tour or attend an outdoor event.
New Orleans Weather in December
December temperatures usually range from approximately 48°F to 65°F, or 9°C to 18°C.
Winter is relatively mild, but individual days can vary considerably. Sunny afternoons may feel comfortable with a light jacket, while rainy or windy days can feel much colder.
Pack a sweater, long pants, and a wind-resistant jacket. Travelers who feel cold easily may also want a lightweight insulated jacket and a thin scarf.
Cold fronts, rain, and morning fog can affect travel. Allow additional time for driving or airport transportation when visibility is reduced.
Best Time to Visit New Orleans for Good Weather
For many travelers, the best time to visit New Orleans is from March through April or from October through November.
These periods generally offer more comfortable temperatures for walking and outdoor sightseeing. They are especially suitable for exploring the French Quarter, Garden District, Jackson Square, City Park, and the Mississippi River waterfront.
However, pleasant weather does not always mean lower prices. Spring festivals and major events can increase hotel rates and reduce availability. Travelers planning a spring visit should compare hotel cancellation policies and reserve early.
October and November often provide a useful balance between comfortable weather and outdoor activities. November can be particularly appealing to visitors who prefer lower humidity and cooler walking conditions.
Is Summer a Good Time to Visit New Orleans?
Summer can work for travelers who prioritize lower accommodation prices, indoor attractions, or a more flexible itinerary. However, lower hotel prices should not be the only consideration.
Heat and thunderstorms can increase spending on rideshares, indoor activities, food delivery, and itinerary changes. Travelers may also need more rest than expected, reducing the number of attractions they can visit each day.
If visiting between June and September, choose a centrally located hotel where you can rest during the afternoon. Avoid scheduling multiple long outdoor tours on the same day.
Flexible flight and hotel reservations are strongly recommended during the tropical weather season.
New Orleans Hurricane Season
The Atlantic hurricane season officially runs from June 1 through November 30. A hurricane will not affect New Orleans throughout this entire period, but the possibility of tropical storms and hurricanes should be part of trip planning.
August and September generally require the most attention. Tropical weather can affect flights, local transportation, hotel operations, tours, and public attractions even when a storm does not directly make landfall in the city.
Before booking a summer or early fall trip, review the following:
- Airline change and cancellation policies
- Hotel refund and weather-related cancellation rules
- Tour operator rain and emergency policies
- Travel insurance coverage for cancellation and interruption
- Coverage for flight and baggage delays
- Transportation alternatives between the hotel and airport
- Official tropical storm and hurricane updates before departure
Travel insurance policies may exclude a storm once it becomes a known or officially named event. Travelers considering insurance should review coverage soon after making their initial trip payment rather than waiting until severe weather appears in the forecast.
Best Time to Visit New Orleans by Travel Style
Best Time for Walking and Outdoor Sightseeing
March, April, October, and November are the strongest choices for travelers who expect to spend many hours outdoors.
Temperatures are generally easier to manage than in summer, but comfortable weather can also bring larger crowds and higher hotel rates.
Best Time for Festivals and a Lively Atmosphere
February through May provides access to major celebrations, festivals, outdoor performances, and seasonal events.
Event dates can significantly affect hotel prices and availability. Confirm the event calendar before booking nonrefundable flights or accommodation.
Best Time for Lower Travel Costs
Travelers may find lower accommodation prices during portions of summer and early fall. These savings come with trade-offs, including heat, heavy rain, and tropical weather risk.
Compare total trip costs rather than hotel prices alone. Rideshare expenses, indoor attraction tickets, and weather-related changes can reduce the apparent savings.
Best Time for a Quieter Trip
Parts of January, November, and December can offer a calmer experience outside major holiday and event periods.
Check the local event calendar because Carnival activities, holiday celebrations, and special events can quickly change hotel demand.
What to Pack for New Orleans
Comfortable walking shoes are essential in every season. Travelers often spend hours walking, and sidewalks in older neighborhoods may be uneven.
In spring, pack breathable shirts, a light jacket, comfortable shoes, and compact rain protection.
For summer, prioritize moisture-wicking clothing, sunscreen, sunglasses, a hat, and water-resistant footwear. Carry water and plan regular breaks.
In fall, bring lightweight clothing for warm afternoons and a thin outer layer for cooler mornings and evenings.
For winter, pack long pants, sweaters, and a wind-resistant jacket. Layering is more practical than relying on one heavy winter coat.
A compact umbrella is useful throughout the year. During warmer months, a lightweight rain jacket may be easier to carry during long sightseeing days.
Final Thoughts on New Orleans Weather by Month
The best time to visit New Orleans depends on your preferred weather, budget, travel style, and tolerance for crowds.
March, April, October, and November generally offer the most comfortable conditions for walking and outdoor sightseeing. Spring is ideal for travelers who want festivals and a lively atmosphere, while fall often combines pleasant weather with slightly greater itinerary flexibility.
Summer may offer attractive hotel prices, but travelers must prepare for intense heat, humidity, thunderstorms, and tropical weather. Winter is usually mild, although cold fronts and wet weather can create unexpectedly chilly conditions.
Reviewing New Orleans weather by month will help you pack more efficiently and create a realistic itinerary. If you plan to travel between June and November, check tropical weather updates and review the cancellation conditions for your flights, hotel, and tours.
About seven days before departure, begin checking the daily forecast. Review the hourly forecast again immediately before outdoor tours, cruises, and day trips. This final check is more useful for packing decisions than relying only on long-term monthly averages.
