The Cook Islands enjoy a pleasantly warm and sunny climate all year round, but as with any tropical area, it does pay to be sensible about how much time you spend in the sun, especially when coupled with time in the ocean.

If you are unfamiliar with Pacific Islands, what you choose to wear also has a real bearing on how much you will enjoy your stay too.

Humidity can be quite high, so when packing your bags, make sure you leave behind the synthetic fabrics and stick to lightweight cotton and natural fibres. Tee-shirts, shorts, sleeveless dresses are great and don't forget to pack a sunhat and sunglasses and plenty of sunblock.

Even when the weather is wet, it is quite likely the whole day will not pass without sunshine and whether raining or sunny, it's still warm.

June to August are the cooler months, while November to March marks the warmer season, with occasional tropical showers expected.

The drier months from April to November have an average temperature of about 26°C, while the warmer, more humid and damp season runs from December to March.

During this season the temperature ranges between 22°C and 28°C. The table below indicates the prevalence of sunshine and sunshine and even temperatures. Severe weather is rare and infrequent.
