The best time to visit the Whitsundays is the dry season from May to October, when rainfall is low, humidity drops and the trade winds keep the heat comfortable. July and August offer the most reliable sunshine but also the highest prices and the biggest crowds, while September and early October strike the best balance of good weather and lower rates. Use this Whitsundays travel guide alongside the Whitsundays weather by month breakdown to pin down your dates.
Best Time to Visit the Whitsundays for Weather
May to October is the dry season. July and August average only 25 to 30mm of rain each, with highs of 23°C to 24°C (73°F to 75°F), low humidity and up to 9 hours of sunshine a day. The water is coolest at 22°C to 23°C, so wetsuit shorts help on snorkel trips, and the clear days suit the things to do in the Whitsundays list. September and October are warmer again, reaching 26°C to 28°C (79°F to 82°F) by day, with September the driest month of the year at about 15mm.
Best Time to Visit the Whitsundays: Why to Avoid the Wet Season
November to April is the wet season, with most of the region’s 1,770mm annual rainfall falling in these six months. January and February each average 290mm to 320mm, humidity sits near 80 percent, and marine stingers (box jellyfish) are present from November to May. Cyclones are most likely January to March. If you do travel in this window, book refundable where to stay in the Whitsundays options and build in buffer days for weather, and check our Whitsundays travel tips for stinger-suit and packing advice.
Best Time to Visit the Whitsundays for Prices
Rates peak in July, August and the December to January school holidays, when resort rooms on Hamilton Island and the mainland Whitsundays neighborhoods can sell out months ahead. The cheapest months are February and March, after the school holidays and before Easter, when many operators discount tours and accommodation by 20 to 40 percent. May, June and November are shoulder months with moderate prices and fewer crowds than peak winter.
