Cyclones on the Cocos Islands

Cyclones only occur occasionally on the Cocos Islands. On average, they happen about 3 times a year.

The typical cyclone season depends on the summer monsoon. In the months before (May to June) and after (October to November), the most severe storms occur.

The Cocos Islands have certainly been affected by the foothills of several cyclones, but during the past 12 months no cyclone reached the inhabited areas on land.
