Wellington’s Climate: What to Expect

Wellington has a temperate oceanic climate — mild through all four seasons, with no extreme heat or cold, but a persistent and sometimes fierce wind that defines the city’s character. If there’s one thing Wellington is famous for, it’s the wind: the city consistently records some of the highest average wind speeds of any capital city in the world, driven by its position at the narrow Cook Strait between the North and South islands.

Seasonal Summary

Wind

Wellington’s wind comes primarily from the north and northwest in summer, and from the south and southwest in winter. The southerly change — a rapid shift from warm northerly winds to cold southerlies — is one of Wellington’s most characteristic weather events. A warm, still morning can become a cold, blustery afternoon within hours. Average wind speeds fluctuate between around 23 km/h and 27 km/h throughout the year, with gusts well above that during storm events.

The strongest winds tend to occur in spring (September–November) and can reach gale force during Cook Strait weather systems. For outdoor activities, calm mornings are the most reliable window — Wellington often settles in the early hours before the day’s wind picks up.

Rainfall

Wellington receives around 1,250 mm of rain annually, spread fairly evenly through the year. There is no true dry season, but the period from November to March is somewhat drier on average. The wettest months are May through August, when frontal systems push through regularly. Rain tends to come in short bursts rather than extended grey periods — Wellington is rarely overcast for days on end the way some New Zealand cities can be.

Temperature

Daytime temperatures in summer average around 20–21°C, occasionally reaching the mid-to-high 20s during a settled northerly spell. Winter days average around 12–13°C. Frost is rare in the city centre, though the surrounding hills and Hutt Valley see more frost events in winter. Snow at sea level is very unusual — a dusting happens perhaps once every few years during an intense polar blast.

Best Time to Visit Wellington

Autumn (March to May) is widely considered the most pleasant time to visit. Temperatures remain mild, the wind tends to ease compared to spring and summer, and there are often long clear stretches. Summer (December to February) is the warmest and sunniest period, though wind can still make outdoor events unpredictable. Winter is mild enough for most activities — the city doesn’t shut down — but pack layers and expect more rain.

What to Pack for Wellington

Whatever the season: a windproof layer is essential. Wellington’s wind is consistent enough that even on warm days, a sheltered spot can feel completely different from an exposed one. Waterproof footwear and a rain jacket are useful year-round. In winter, add thermals and a warm hat for walks on the hills.

Frequently Asked Questions

Why is Wellington so windy?
Wellington sits at the northern end of Cook Strait, a narrow channel between the North and South islands that funnels and accelerates prevailing westerly winds. The city’s topography — surrounded by hills with harbour openings — adds to the effect. Wellington consistently ranks among the world’s windiest capital cities by average wind speed.

Does it snow in Wellington?
Snow at sea level in Wellington is very rare — perhaps once every few years during an intense cold polar blast. The hills around the city (including the Remutaka Range) receive occasional snow in winter, but the city itself rarely sees more than a brief flurry if anything at all.

What is the best month to visit Wellington?
March and April tend to offer the best combination of mild temperatures and calmer conditions. February is the warmest month but can be windy. December and January are also popular for the longer daylight hours and summer festivals.

How much rain does Wellington get?
Wellington receives around 1,250 mm of rain per year. Rain is fairly evenly distributed through the seasons, though the winter months (June–August) are the wettest. There is no long dry season, but November to March tends to be drier on average.
