Cook Islands Weather

Seasonal variations are slight in the Cook Islands, with temperatures ranging between 18°C and 28°C (64-82°F) in the winter months (May to October) and 21°C and 29°C (70-84°F) in the summer (November to April). The wet season is from December to March, when around 25cm (10in) of rain can fall each month; this is also the most likely time for cyclones, which are becoming more frequent due to warming seas across the South Pacific. The wet season is also the hottest and most humid time of the year - it can get quite sticky and uncomfortable, so bring along some cool, light clothes. The winter nights can sometimes be quite cool, even chilly, so if you're visiting at this time of year, a warm sweater or jacket will probably come in handy.
