Septermber Climate of the North Island
Due to the rise in temperature, the heat on the northern island returns slowly. However, with the resurgence in precipitation, the rains are still part of the weather in New Zealand throughout September. According to the exposure of the localities facing the wind coming from the Sea of Tasman, the city of Auckland and that of Hamilton are the wettest.
On the east coast of the northern island, temperatures in the middle of the day are more comfortable. However, rainfall events are becoming more numerous.
September Climate of the South Island
The consequence of the rise in temperature is also palpable on the island of the south. Cities like Christchurch are now experiencing warmer temperatures. With the relative rarity of the rainy episodes, the atmosphere is accompanied by a pleasant freshness. High-altitude localities however, like Queenstown, remain disadvantaged by the cold - with temperatures still below zero. In the south, humidity persists.
