Wellington’s weather has a reputation for being unpredictable, but planning your trip doesn’t have to feel that way. The best time to visit Wellington for comfortable weather is during late summer and early autumn, from March to May.
These months bring mild temperatures, fewer crowds, and a calmer vibe than the busy summer peak. That’s when you can really settle in and soak up the city.
Each season in Wellington brings its own flavor. Summer offers long daylight hours and warmth. Winter gets cooler and windier, but you won’t bump into many tourists.
Spring and autumn sit in the middle, with shifting temps and bursts of color that make the city pop in their own way.
When you know how Wellington’s climate shifts, you can pick the kind of trip you want. Maybe you picture sunny days by the waterfront, or crisp walks in the hills, or just a quieter visit with less hustle.
Your timing really shapes the experience. Here’s a look at Wellington’s climate, seasonal highlights, and a few tips to help you choose the right time for your visit.
Overview of Wellington’s Climate
Wellington sits in a temperate oceanic climate, thanks to its coastal spot and those famous winds. You’ll get mild temperatures year-round, regular rainfall, and a real contrast between the sunny summer months and the wetter, gloomier winter.
Seasonal Weather Patterns
Wellington’s seasons flip the script compared to the Northern Hemisphere. Summer (December–February) brings the sunniest and mildest weather, with average highs around 21 °C (70 °F).
You’ll get long days, and while rain still pops up, it’s less frequent than in winter.
Autumn (March–May) stays pretty mild as temps slowly cool off. This time feels settled, with fewer crowds and great conditions for getting outdoors.
Winter (June–August) gets wetter and windier. Average highs dip to about 12–13 °C (54–55 °F). Snow almost never shows up, but those strong southerly winds can cut right through you.
Spring (September–November) is all over the place, with sun and rain swapping out fast. Temperatures start to climb, making it a true transition season.
Temperature Ranges Throughout the Year
Wellington doesn’t do extremes. The warmest month, February, averages 18 °C (64 °F), and daytime highs usually hit 21 °C (70 °F). Sometimes, it’ll sneak up to 25–26 °C (77–79 °F).
July is the coldest, with an average of 10 °C (50 °F) and lows around 7 °C (45 °F). Frost hardly ever shows up, and freezing temps are rare.
Here’s a quick rundown of monthly averages:

Precipitation and Rainfall Trends
Rain comes pretty steadily all year in Wellington, adding up to about 1,250 mm (49 in) annually. There’s no real dry season, just a bit more rain in winter.
May through August bring the heaviest rainfall, with 120–135 mm each month and about 12–13 wet days. You’ll also see the least sunshine during this stretch.
January and February dry out a bit, with 75–80 mm of rain and only 7 wet days per month. Still, showers can sneak up, so packing a rain jacket is smart.
Wind shapes Wellington’s weather, too. Gusts can bring quick showers but also clear the skies fast, so you might see rain and sun in the same hour.
Best Time to Visit Wellington for Ideal Weather
Wellington’s climate stays mild, but each season brings its own blend of temperatures, wind, and rain. You’ll really notice the comfort differences in autumn, summer, and spring, and each has distinct benefits for travelers.
March to May: Autumn Highlights
Autumn brings mild temperatures with highs that ease down from 16–18 °C (low 60s °F) to about 14 °C (upper 50s °F). It’s a great time for walking the waterfront or exploring the hills—without the summer crowds.
Rain picks up later in autumn, so toss a light jacket or umbrella in your bag. Evenings cool off, which makes outdoor dining or a stroll through the Botanic Garden feel pretty nice.
This season also comes with cultural perks. Festivals like the NZ Fringe and International Comedy Festival usually happen now, adding extra fun to your trip.
If you want good weather and fewer tourists, autumn really stands out as one of the best times to visit Wellington.
December to February: Summer Advantages
Summer is the warmest time of year, with daytime highs in the 20–23 °C (upper 60s to low 70s °F) range. Days stretch long, and sunshine is more reliable, so it’s perfect for hiking Mount Victoria or catching the ferry across the harbor.
Wellington feels extra lively in summer. Families travel during school holidays, and the city’s event calendar is packed. Beaches like Oriental Bay get busy, though the water stays pretty cool.
You’ll see higher hotel rates and more people at the main sights. If you want the steadiest weather, summer’s a good bet, but book your stay early.
September to November: Spring Appeal
Spring slowly warms up, with temps going from 9 °C (upper 40s °F) in September to 16 °C (low 60s °F) by November. Windy days still pop up, but fresh blooms and clearer skies make the city feel alive.
The Wellington Botanic Garden shines in September, when the tulips burst into color. It’s a great time for outdoor walks and snapping photos.
Crowds thin out compared to summer, and hotel prices often drop. Weather swings between calm and breezy, but spring gives you a sweet mix of affordability, beauty, and mild conditions for a visit.
Understanding Wellington’s Unique Weather Factors
Wellington’s climate owes a lot to the strong winds from Cook Strait and steady humidity. These factors change how warm or cool the city feels, even when the numbers look mild.
Wind Patterns and Their Impact
People call Wellington the “Windy City” for a reason. The Cook Strait funnels air between the North and South Islands, so gusts happen a lot.
Winds from the northwest usually dominate, but southerlies can sweep in fast and bring a chill.
Expect wind speeds that beat most other New Zealand cities. Sometimes, it’s just a gentle breeze, but strong gusts can show up out of nowhere.
Wind changes how the temperature feels. A mild 15 °C day can feel much colder if a southerly is blowing. On the flip side, a warm northerly can make summer afternoons feel hotter than the actual temp.
If you’re planning lots of time outdoors, bring clothes that can handle wind. A light, windproof jacket beats heavy layers most days.
Humidity Levels by Season
Wellington’s humidity stays moderate—nothing like the tropics—but it still matters. In summer, you’ll see relative humidity around 70–75%. Winter bumps it up closer to 80%.
So, summer days can feel a bit sticky, especially if the wind dies down. In winter, the dampness makes cool air feel chilly, even if it’s not that cold.
Wellington doesn’t get wild swings in humidity. The sea keeps the air moist year-round.
When you pack, remember humidity changes how indoor spaces feel. Light, breathable clothes work best in summer. In winter, layers that block dampness will keep you more comfortable than just thick sweaters.
Seasonal Festivals and Major Events
Wellington’s calendar is packed with cultural, musical, and food events that show off its personality. These gatherings usually line up with seasonal changes, giving you a taste of local life and the city’s lively vibe.
Matariki and Winter Celebrations
Matariki, the Māori New Year, usually lands in mid-winter. People celebrate the night sky with storytelling, art, and community events.
It all centers on the rising of the Matariki star cluster—a time for reflection and planning ahead.
Public events include light displays, performances, and shared meals. These moments offer a window into Māori culture and a chance to connect with locals.
Since winter in Wellington can be cold and windy, most celebrations mix outdoor stargazing with indoor programs. You get the vibe without braving the weather for too long.
Wellington Jazz Festival and Beervana
The Wellington Jazz Festival draws musicians from around the globe. You can catch shows in theaters, bars, and cozy clubs, so there’s something for every mood.
The lineup covers everything from classic to experimental jazz.
In August, Beervana takes over Sky Stadium, spotlighting New Zealand’s craft beer scene. Dozens of breweries pour samples, food trucks roll in, and live entertainment keeps things lively.
You get to try unique brews and chat with the people who make them.
Both events thrive in the cooler months. They offer indoor fun that fits Wellington’s winter, and you get to dive into the city’s music and food scene without worrying about the weather.
Wellington on a Plate and Culinary Events
Wellington on a Plate is the city’s biggest food festival, running every late winter. It stretches over several weeks and features special menus, pop-ups, and food competitions.
You can try creative dishes from top chefs or grab bites from casual spots—all focused on local ingredients.
Burger Wellington is a festival highlight, with restaurants battling to make the best burger. Locals and visitors both go wild for it.
Workshops and themed dinners round out the schedule. If you love food, this is the season to sample a ton of flavors and see the city’s creative dining side.
Cubadupa and Spring Festivities
Cubadupa is Wellington’s biggest street festival, taking over Cuba Street in spring. The whole area turns into a giant stage for music, dance, and art.
Streets close to cars, so you can wander between performances and food stalls.
The festival leans into creativity and community. You’ll spot brass bands, acrobats, and all kinds of performers out in the open.
Food vendors serve up everything from local bites to global flavors, matching the festival’s energy.
Spring also brings flower displays and events at the Wellington Botanic Garden, especially the annual tulip bloom. This combo of color and celebration makes spring a fresh, energetic time to visit.
Travel Tips for Visiting Wellington in Different Seasons
Wellington’s weather can flip fast. The city’s hills and harbor winds often make it feel cooler than the forecast says.
If you plan ahead with clothing and timing, you’ll stay comfortable and avoid any unnecessary stress while exploring.
What to Pack for Each Season
In summer (December–February), you’ll want to toss in some light layers, sunscreen, and a hat. The sun feels pretty intense, and it’s surprisingly easy to get burned, even on a breezy day.
A light jacket comes in handy after sunset when the wind likes to pick up.
During autumn (March–May), I usually pack both short sleeves and a few cozy layers. Temperatures dip into the 50s or 60s °F (10–18 °C), and rain seems to show up more often.
A compact umbrella or a waterproof jacket saves the day when showers hit.
For winter (June–August), expect chillier days in the 40s–50s °F (7–13 °C) with gusty winds. I always grab a windproof coat, some warm layers, and sturdy shoes to stay comfortable outside.
Gloves and a hat make a big difference when it’s colder.
In spring (September–November), the weather just can’t make up its mind. Pack a bit of everything, including a rain jacket, since the day can flip from sunny to damp and windy.
If you plan to wander through gardens or along the waterfront, comfortable walking shoes are a must.
Crowd Levels and Accommodation Advice
Summer draws the biggest crowds, with families flocking in during school breaks. Hotels and rentals fill up fast, and prices shoot up.
If you’re set on visiting this time, it’s best to book well ahead.
In autumn, things calm down, and you’ll notice more open rooms and reasonable prices.
It’s honestly a sweet spot—decent weather without the big crowds.
Winter feels the quietest. You’ll see way fewer tourists at the main sights, and accommodation prices usually drop.
Just keep in mind, some outdoor activities can feel less inviting when it’s windy and cold.
By spring, travelers start rolling in again, especially if there’s a big event like the World of WearableArt Awards. Booking early makes sense if your trip lines up with a festival.
Otherwise, you’ll still have more options than you would in summer.
