Wellington’s weather is famously changeable – the live forecast above gives the short-term picture, while the details below explain what drives the capital’s wind, rain and temperature swings throughout the year.
What makes Wellington’s weather so changeable?
Wellington sits on Cook Strait, a natural wind funnel that funnels strong northwesterlies through the city. Cold fronts and low-pressure systems race across the strait, bringing rapid shifts in cloud, rain and wind. Even a calm morning can turn gusty by lunchtime, especially in spring. The city’s hills and harbour also create localised pockets of drizzle or clearer skies within a few kilometres.
How do the seasons affect your visit?
Summer (December–February) offers mild to warm days, but the wind often keeps it feeling cooler than the thermometer suggests. Autumn and spring are highly variable – expect sunshine, showers and squalls in the same day. Winter (June–August) brings colder temperatures, more persistent rain and occasional frosts inland. For a broader picture, check the New Zealand Weather hub and Weather Radar for live tracking of approaching systems.
