Wellington is a year-round destination, but choosing what to pack can be surprisingly difficult. The temperature may look mild on a weather app, yet strong coastal winds can make it feel several degrees cooler, especially around the waterfront, exposed walking trails, and lookout points.
New Zealand’s capital is rarely extremely hot or bitterly cold. However, Wellington is known for rapidly changing conditions, frequent wind, and occasional rain throughout the year. Sunshine, clouds, wind, and short showers can all occur on the same day.
This Wellington weather by month guide explains the city’s seasonal climate, average daytime and nighttime temperatures, the best time to visit Wellington, and what to wear during each month.
Understanding Wellington’s Climate
Wellington sits at the southern end of New Zealand’s North Island, close to the Cook Strait. Its coastal location and surrounding hills contribute to its famously windy and changeable weather.
Because Wellington is in the Southern Hemisphere, its seasons are opposite to those in North America and Europe.
- Summer: December to February
- Autumn: March to May
- Winter: June to August
- Spring: September to November
Temperatures remain relatively moderate throughout the year. Average daytime temperatures are generally around 12°C to 21°C, depending on the season.
The wind makes the biggest difference to how the weather feels. Conditions around Wellington Waterfront, Mount Victoria Lookout, Red Rocks, and exposed coastal trails can feel much cooler than they do in sheltered parts of the city.
A lightweight windproof jacket is therefore useful in every season. An ordinary umbrella may be difficult to use during strong gusts, so a hooded water-resistant jacket is often a more practical choice.
Wellington Weather by Season
Summer in Wellington: December to February
Summer is the warmest and one of the most popular times to visit Wellington. Daytime temperatures generally range from 18°C to 21°C, while nighttime temperatures are usually around 12°C to 15°C.
Unlike destinations with hot and humid summers, Wellington normally remains comfortable for walking and outdoor sightseeing. Longer daylight hours make it easier to visit the waterfront, Oriental Bay, Mount Victoria, Zealandia, and the city’s surrounding coastal areas.
Even during summer, Wellington can feel cool when the wind picks up. Pack T-shirts, lightweight trousers or shorts, a long-sleeved shirt, and a light windproof jacket.
New Zealand’s ultraviolet radiation can be strong, even when the weather feels mild. Sunscreen, sunglasses, and a secure sun hat are essential for outdoor activities.
Autumn in Wellington: March to May
Autumn begins with mild conditions in March before becoming noticeably cooler in April and May.
March is particularly appealing for travelers who want pleasant weather without the busiest part of the summer holiday period. Daytime temperatures remain comfortable for walking, sightseeing, and outdoor dining.
By May, mornings and evenings can feel considerably colder, especially when wind and rain arrive together. Pack long-sleeved tops, a lightweight sweater, and a wind-resistant jacket. A fleece or light insulated jacket becomes useful toward the end of the season.
Winter in Wellington: June to August
Winter in Wellington is cool, windy, and occasionally wet. Heavy snowfall is not a normal feature of the city center, but damp conditions and southerly winds can make the temperature feel much colder.
Average daytime temperatures are usually around 12°C to 14°C, with nighttime temperatures commonly falling to approximately 7°C to 9°C.
Winter is a good time to focus on Wellington’s indoor attractions. The Museum of New Zealand Te Papa Tongarewa, city galleries, cafés, restaurants, cinemas, and craft beer venues provide plenty of options when outdoor conditions are unsettled.
Wear several adjustable layers rather than relying on one heavy coat. A thermal base layer, sweater or fleece, and waterproof windproof outer jacket create a practical combination. A scarf and lightweight gloves can also be useful.
Spring in Wellington: September to November
Temperatures gradually rise during spring, but this can be one of the most changeable periods of the year.
A morning may begin with sunshine before becoming cloudy, windy, or showery in the afternoon. September can still feel similar to winter, while November often brings milder conditions suitable for longer outdoor activities.
Long-sleeved tops, a light sweater, and a windproof outer layer are recommended. Clothing that can be removed or added easily will help you adjust to changing temperatures throughout the day.
Wellington Weather by Month
Wellington Weather in January
January is one of the warmest and sunniest months in Wellington. Average daytime temperatures are usually around 20°C, while nighttime temperatures are approximately 14°C.
Long daylight hours make January ideal for waterfront walks, outdoor attractions, coastal drives, and day trips.
Pack T-shirts, lightweight trousers or shorts, comfortable walking shoes, and a light windbreaker. Sunscreen and sunglasses are essential.
Wellington Weather in February
February is generally the warmest month of the year. Daytime temperatures often reach approximately 20°C to 21°C, while nighttime temperatures are around 14°C to 15°C.

Pack summer clothing with a lightweight jacket or cardigan for evenings and exposed locations.
Wellington Weather in March
March remains pleasantly mild, with daytime temperatures of approximately 19°C to 20°C and nighttime temperatures around 13°C to 14°C.

Wellington Weather in April
In April, average daytime temperatures fall to around 17°C, with nighttime temperatures of approximately 11°C to 12°C.
Days can still be comfortable for sightseeing, but temperatures may drop quickly after sunset. A long-sleeved shirt, lightweight sweater, and jacket are suitable for most conditions.
Include a compact rain jacket if you plan to spend significant time outdoors.
Wellington Weather in May
May marks the transition toward winter. Average daytime temperatures are around 15°C, while nighttime temperatures are approximately 9°C to 10°C.
Cloudy weather, wind, and rain can make it feel colder than the forecast suggests.

The weather can change rapidly. Wind, sunshine, cloud, and short showers may all occur within a single day.
Pack a long-sleeved top, lightweight sweater, and hooded windproof jacket.
Wellington Weather in October
October brings daytime temperatures of approximately 15°C to 16°C, with nighttime temperatures around 9°C to 10°C.
It is a pleasant month for gardens, wildlife attractions, and city walks, but the difference between sheltered and exposed locations can be noticeable.
Wear light layers and keep a water-resistant jacket in your day bag.

Wellington Weather in December
December marks the beginning of summer. Daytime temperatures generally range from 18°C to 20°C, while nighttime temperatures are approximately 12°C to 14°C.
Longer daylight hours allow travelers to fit more outdoor activities into the day. Summer clothing is appropriate, but a lightweight windproof jacket should still be included.
Flights and accommodation may become more expensive around Christmas and New Year, so early booking is advisable for late-December travel.

What Is the Best Time to Visit Wellington?
For most first-time visitors, the best time to visit Wellington is from January to March. These months normally offer warmer temperatures, longer daylight hours, and favorable conditions for combining city sightseeing with outdoor activities.
January and February are ideal for travelers who prioritize warm weather. However, they also overlap with New Zealand’s main summer holiday season, so popular accommodation and transportation options may sell out earlier.
March offers one of the best overall balances. Temperatures remain relatively mild, while the busiest summer vacation period has usually passed.
April is another good option for travelers who enjoy walking and cooler weather. Evenings become colder, but daytime conditions can still be comfortable.
Travelers interested primarily in museums, restaurants, cafés, and cultural attractions can visit during winter. Indoor activities make it relatively easy to build a weather-resistant itinerary.
October and November are suitable for spring gardens and outdoor walks, although visitors should be prepared for wind and rapid weather changes.
Important Weather Conditions to Watch
Strong Wind
Wind is the most important weather factor to consider in Wellington. It can affect exposed lookouts, coastal trails, flights, and ferry services.
Check the latest forecast before visiting Mount Victoria, Red Rocks, or other exposed locations. Strong gusts may also make an umbrella impractical.
Rain and Slippery Walking Surfaces
Rain can occur in any season. Wellington’s hills, steps, and coastal paths may become slippery after a shower.
Choose walking shoes with suitable grip and carry a lightweight hooded rain jacket.
Strong UV Radiation
UV exposure can be high even when temperatures are mild or the sky is partly cloudy.
Use broad-spectrum sunscreen with an SPF of at least 30, reapply it during extended outdoor activities, and carry sunglasses and a secure hat.
Cook Strait Ferry Conditions
Travelers taking a ferry between Wellington and the South Island should pay particular attention to marine conditions.
The weather in central Wellington may appear manageable while conditions in the Cook Strait are rough. Check the ferry operator’s service notices and the latest marine forecast before departure. Allow extra time between a ferry arrival and any connecting transport.
What to Pack for Wellington
A practical Wellington packing list should include:
- A lightweight windproof and water-resistant jacket
- Comfortable walking shoes with reliable grip
- Long-sleeved and short-sleeved tops
- A sweater or fleece
- Lightweight trousers
- Broad-spectrum SPF 30 or higher sunscreen
- Sunglasses
- A secure hat
- A reusable water bottle
- A scarf and lightweight gloves for winter
- A small day bag for extra layers
A folding umbrella can be helpful during light rain, but it should not replace a hooded jacket. Strong gusts may make umbrellas difficult to use near the waterfront and at exposed viewpoints.
How to Plan a Weather-Resistant Wellington Itinerary
Avoid filling an entire day with exposed outdoor attractions. Instead, alternate between indoor and outdoor activities.
For example, you could visit Mount Victoria in the morning, explore Te Papa in the afternoon, and finish with dinner in the central city. If strong wind or rain affects the morning, the two activities can be reversed.
Keep Zealandia, waterfront walks, lookout points, and coastal trails flexible whenever possible. Museums, cafés, galleries, and covered markets can serve as alternatives during unsettled weather.
Check an hourly forecast the evening before and again on the morning of your visit. Pay particular attention to wind gusts, rainfall timing, and weather warnings rather than relying only on the daily maximum temperature.
Final Thoughts
Wellington weather by month is relatively moderate, but wind and rain can make conditions feel very different from the reported temperature. Travelers should consider wind speed, rainfall, and apparent temperature when choosing what to wear.
January through March is generally the best period for warm weather and outdoor sightseeing. March and April provide a good balance for travelers hoping to avoid the busiest part of summer, while winter works well for museums, cafés, and food-focused trips.
Regardless of the season, pack adjustable layers and a windproof outer jacket. Check the latest forecast before departure, keep exposed outdoor activities flexible, and confirm ferry or flight conditions when severe weather is possible.
With the right clothing and a flexible itinerary, Wellington can be an enjoyable destination at any time of year.
