High Season: December to February
Sailing during this season: The weather in New Zealand is never so miserable that there’s no point in going, but with temperatures ranging from 20-30 degrees Celsius, the summer months are the peak cruising times. This also makes it probable to be more expensive and more crowded. It is also worth noting that the South Island can be colder than the North Island, even in summer.
Low/Shoulder Season: May to August
Sailing during this season: Cruises to New Zealand are offered all year round, and there are always things to see and do. May to August are the coldest months, and daylight hours are shorter, so cruising options are limited. The weather from September to November is, however, the hardest to predict.
