What season is it in New Zealand?

New Zealand is located in the southern hemisphere, and the seasonal changes are opposite to those in the northern hemisphere: spring is September to November, summer is December to February, autumn is March to May, and winter is June to August. The average temperature in September and October is between 15 and 2℃, which is the best time to travel. From November to April every year, especially from the school holiday to January next year, it is best to make a reservation before traveling to New Zealand, otherwise there is probably no place to live.
