When To Go - Best Time to Visit The Cook Islands?

Cook Islands Christian Church
The CICC is vitally important to most islanders for whom it has a profound influence on everything they do every day. Visitors are most welcome to attend a church service which take place on Sunday mornings and evenings and several mornings during the week. The service is in Maori but foreign visitors are made to feel very welcome as long as they dress smartly in long dresses and trousers.

Culture
Cook Islanders consider themselves true Polynesians and are very proud of their Maori and Maohi heritage. However, equal importance needs to be given to the influence of Christian missionaries on this society. Today, an unusual yet harmonious blend of Christianity and ancient pagan traditions exists in the Cooks and is a wonderful example of how two vastly different beliefs can coexist peacefully.

Climate data provided by Weather2Travel.com

The climate in the Cook Islands is tropical and generally pleasant year round with steady humidity levels and temperatures.

December to March is regarded as the rainy season when there is a greater chance of cloudy days and the occasional storm, but you’d be unlucky to have continuous rain for days on end.

Temperatures are slightly higher at this time of year, but even the stickiest days are tempered by sea breezes while short and sharp rainstorms tend to cut the humidity and leave the islands refreshed and renewed.
