This comprehensive guide explores the ins and outs of Wellington’s weather and climate, from seasonal changes to the factors that make this city a dynamic environment year-round.
Geographic Setting and Its Influence on Wellington’s Climate
Wellington is uniquely positioned at the southern tip of New Zealand’s North Island, bordered by the Tasman Sea to the west and the Pacific Ocean to the east, with the narrow Cook Strait separating the North and South Islands. This strategic location exposes Wellington to a range of maritime influences, resulting in weather patterns that can shift rapidly.
