The Whitsundays enjoy a sub-tropical climate so the temperature is almost always enjoyable and sunny. From April to September the trade winds blow and the best cruising weather is usually any time between May and November.

The wet season runs from January through until March. The windiest months are from March through until May and from June the weather tends to settle. Temperatures are rarely below 16° or above 31° throughout the year.

Most people find winter the most pleasant with beautiful warm sunny days and cooler nights. Summers are hot with the odd tropical shower and the humidity increases.

Winds are predominately from the south and south-east, however between November and March, northerly winds are also common.


School holidays are always the busiest time of year to hire a catamaran in the Whitsundays so you do need to book in advance for these periods. There are four sets of school holidays, April, June/July, September/October and Christmas and New Year.

The whale watching season runs from July to September. During these months don’t be surprised if you see a whale breaching out in the Whitsunday Passage.

August is the start of the sailing season with both Airlie Beach and Hamilton Island Race Week taking place during this month.

The peak season runs from September through October and again over the busy Christmas period. This is mainly due to the weather and school holidays. It is best to book for these months 12 months in advance to ensure you secure the catamaran you want.

The stinger season runs from October through until May. It is recommended you wear a stinger suit during these months.
