New Zealand’s seasons are opposite those in North America and Europe.
Wellington’s average daily temperature is 13 (°C), slightly above the national average, but the city has also earned a nickname of Windy Wellington thanks to the Roaring Forties—prevailing westerly winds that scour the Southern Hemisphere between latitudes of 40 and 49 degrees. As a result, the city basks in only am average of 40 calm days per year.
Wellington’s warmest months—December, January, and February, with temperatures of 18°C to 25° which coincide with peak tourist season. Avoid travelling December 20 through January 31—and other major holidays—when Kiwis take vacation. Though temperatures rarely fall below freezing, off-season for travellers falls during the coldest months, June, July, and August, when temps range from 8°C to 12°C .
Come spring (September, October, and November), the countryside comes alive—a gorgeous time to visit as long as you tote your umbrella and light jacket. In fall (March, April, and May), temperatures are pleasant, crowds are fewer, and prices are better, which makes it the perfect time to visit.
