Weather & Tides

Weather & Climate

On your visit to our tropical Island you can expect warm days and balmy evening all year round.

The islands experience two main seasons that often overlap: the trade wind season from May/June to September/October, and the calmer doldrum season from November through to May.


No matter what the season, you will always experience temperate weather. With a minimum evening temperature rarely dropping below 24°C and water temperature consistent above 26 *C.

Humidity ranges between 70%-80% so you certainly won't need to pack any winter clothes when visiting this tropical haven! 


Rainfall & Wind

Whilst a rainy day is thought to be undesirable during a relaxing holiday, it isn’t always a bad thing. The rain on Cocos is very warm, and something special to experience! All sorts of fun can still be had, especially with water activities in the rain. 

Not to worry though, most days on Cocos Islands are beautiful and sunny, with an average annual rainfall of 2000mm.


You can expect to see less rain and wind during the Doldrums season, December – January in particular. Whereas higher rainfall typically occurs during March through to July. If kitesurfing is your thing, this is the best time to journey over to Cocos as it’s also our Trade Wind season!



Tides play an important role in many of our water activities. For all of the keen surfers out there, be sure to check what the tides are doing as most of our surf spots require a tide of at least 0.6m.


As for the adventurers; The Motorised Canoe Safari allows access to the southern end of the lagoon but only on a high tide due to the shallow draft of their vessels! A low tide allows foot access to Pulu Maraya for a memorable snorkel and reef walk.


Drop in to the Visitor Centre if you are planning a tide-dependent activity with tide charts available for sale at the Community Resource Centre, or visit the Bureau of Meteorology to see more about tides and anomaly effects on Cocos.
