Visiting West Island in May

May weather

May feels warm and very humid on West Island, with highs and lows both around 28°C. Rain falls on many days, and cloudy skies cut the sunshine to about four hours daily. April is wetter, but May is still showery; June gets a little more rain.

You can still enjoy the lagoon, coastal walks and a slow look around the island between showers. The Cocos Islands' clear water can make snorkelling appealing, but cloud and rain may limit visibility. Don't count on long, sunny beach days or dry conditions for every outing.

Events and island life

There isn't a major annual festival fixed in May on West Island. Mother's Day is observed in Australia, but it isn't a public holiday. May also falls outside the August-to-October period that's best overall for a visit, so island life is generally quieter than in those popular months.

If you hate crowds, May may suit you better than peak season. Fewer visitors can mean more choice of accommodation and flights, though fares and availability still depend on the day you travel.

Getting around

Travelling with kids? Keep plans flexible: frequent showers can interrupt beach time, so pair it with an easy indoor break or a trip to the airport's small visitor displays.

A useful local tip: use the ferry between West Island and Home Island to see more than the airport end of the atoll. Check its current timetable locally, as it's the key link between the islands. On Home Island, you'll find the Cocos Malay community and a very different feel from West Island's small settlement. May's wet weather can make a ferry crossing less pleasant, so avoid squeezing it between tightly timed plans.
