Cook Islands weather by month
Source: Meteorological data for the Cook Islands is based on weather statistics gathered for the 30-year period 1992 to 2021 by the Cook Islands Meteorological Service at the closest weather station: Rarotonga International Airport (RAR), located less than 3km (2mi) west of Avarua Harbour. Additional climate data is sourced from the United States National Oceanic and Atmospheric Administration (NOAA).
Advice on the best time to visit a particular destination is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
