Cocos Keeling Weather for Sailors

The islands are under the influence of the SE trade winds for most of the year. The winds are strongest in August. During the cyclone season, from December to March, the winds are lighter. The islands are rarely affected by tropical storms.

However, if a Cyclone Watch and Act (orange) alert for the Cocos (Keeling) Islands is issued by
the Australian Bureau of Meteorology, the Port Manager will issue a Securite on VHF
Channel 20. Vessel Masters will be advised to depart the Port Refuge immediately and
sail away from the threat.
