With a climate similar to that of Hawaii, the Cook Islands have sunny tropical weather most of the year. Located below the equator in the southern hemisphere, the seasons here are reversed, which means that November through April are summer months, while May through October is winter in the Cook Islands.

The climate here is pleasant throughout the year, with brief heavy downpours between December and March, which coincide with cyclone season. During this period it rains quite a lot and can get rather humid. Winter is a good time to visit, with pleasant summer days and cool nights. A light jumper or sweater is sometimes necessary in the late evening.

If you are visiting the Cook Islands between November and April, look forward to bright sunny days with sticky afternoons. On Rarotonga, rain clouds can be seen throughout the year, especially in the interior of the island, but don’t worry as the coast is more often than not clear and sunny. One downside to summers in the Cook Islands is more mosquitoes.

April, May, September, and October are usually regarded as the best months to visit with an ideal blend of sunshine and pleasant weather.
