Humidity hangs around 75–80%. The air holds some moisture, but the constant sea breeze keeps things from feeling sticky.

UV levels run high. Even on cloudy days, you’ll want sunscreen, sunglasses, and a hat. The long days and clear skies make it a great time for sightseeing, hiking, or hanging out by the waterfront.
Wind Patterns During Christmas
People call Wellington the “Windy City” for a reason, and December proves it. Average wind speeds range from 23 to 27 km/h (14–17 mph), with even stronger gusts along the coast and hills.
Winds usually blow in from the northwest, but sometimes a southerly change brings cooler air and the odd shower. These shifts can happen fast, so layering up is a smart move.

How Weather Impacts Christmas Activities
Christmas in Wellington lands right at the start of summer, so you get long daylight, moderate temperatures, and plenty of wind. These factors shape how people celebrate, where they gather, and what you’ll want to pack if you’re visiting.
Outdoor Events and Festivities
Daytime highs hover around 17–18°C (63–65°F), and evenings cool to about 13°C (55°F). This mild weather means many Christmas events happen outside. Markets, concerts, and parades pop up in open spaces, but you should expect some wind—it’s just part of Wellington.
Rain falls on about 13 days in December, so a few events might get moved or shortened. Still, you’ll find open-air performances, light displays, and community gatherings, especially when the weather cooperates.
With over 14 hours of daylight, celebrations stretch into the evening without needing much artificial light. Outdoor dining, waterfront festivals, and family picnics are all big parts of the season.
Popular Beaches and Waterfronts

You’ll see some locals braving the water, but most people stick to the shore.
Strong winds define the city. On breezy days, swimming or paddleboarding can get tricky, but sailing and windsurfing become more appealing. You can always enjoy a stroll along Oriental Bay or check out the waterfront markets.
If you want quieter spots, try smaller bays or coastal walks. The weather usually works for hiking, but bring a jacket since it gets cooler in the wind, especially in exposed areas.
Packing Tips for Visitors
Pack clothes that work for changing weather. Light shirts and shorts are fine for the day, but a sweater or light jacket helps in the evening. Rain is common, so a waterproof jacket is more useful than an umbrella in windy Wellington.
For outdoor stuff, bring comfortable walking shoes, sunglasses, and sunscreen. With over 220 hours of sunshine in December, sun protection is a must, even if it’s cloudy.
If you’ll be by the waterfront, pack layers you can add or shed easily. A hat with a strap is handy—otherwise, the wind might steal it. Swimsuits are optional; only bring one if you’re cool with chilly water.
