New Zealand Season
They are the opposite of the European Seasons. When is it the best time to go? Well that depends on which season you prefer. The Northern Island has soft winters and wet summers.
Spring (September- October-November).
The days become longer but it can be windy (but it is always windy) and rainy. We have an average of 18 degrees. For us Europeans already a nice temperature
Summer (December - January - February)
It is warm, sundy and at the West coast always windy (you be lucky for that if it gets hot). We have an average of 25 degrees.
Autumn (March-April-May)
Temperature drops a bit to an average of 20 degrees and you will get a little bit more rain. Then again we were the whole month march at Auckland and the first 2 weeks we had temperature of 25-30 degrees, no rain, strong sun, windy days. By the end of March the weather turned and we got the first rains. But rains are not as we know in Europe. You get a few drops or you get a short and hard shower. The other moment it is sunny weather again. At Bethels Beach you are protected by the mountains and you often have better weather then elsewhere. My advise, even when it is cloudy or raining get out and do your thing.
Winter (June-July-August)
Seems in the winter it gets to 13 degrees average. For us Europeans we still get treated then.
