Cook Islands Climate & Weather
The climate in the Cook Islands is tropical, fairly constant, and placid. The rainy season coincides with the hottest time of year, between November and March, but the rain usually falls in the form of late afternoon storms. These cool the air temperature and give some welcome relief from the heat, which averages around 82F (28C) at this time of year.
There is also a risk of cyclones and hurricanes during the hot season. Although these violent storms can do serious damage, the Cook Islands generally don't get hit too hard and extreme weather conditions are rare. The worst month for storms is February. The cooler, dry season, when temperatures range from 70F to 80F (20C to 26C), runs from April to October.
The Cook Islands are a year-round destination because the weather ensures it is almost always suitable for swimming and beach lounging, which is the main reason people visit. Prices for accommodation and the like are pretty constant all year, as there is not a 'peak season' for tourism. The best time to visit the Cook Islands is probably in the slightly cooler months when there is no chance of cyclones or serious storms.
