Tips for travelling to the Whitsundays in August

1)	Stay sun safe Whilst weather temperatures in the Whitsundays in August are cooler compared to the hot and balmy summer months, the Queensland sun remains strong at any time of the year! Stay sun safe by remembering the classic ‘slip, slop, and slap’ during your winter escape - time to revel in bright, dry days without the burn!
2)	Pack some warmer clothes August days are bright, clear, and dry, so be sure to pack your favourite swimsuit and breathable clothing for snorkelling, hiking, and island-hopping adventures! As the afternoon sun begins to set, the brisk night begins to cool considerably, so we recommend you pack a pair of jeans and a warm jumper or jacket to keep cosy - especially if you’re out on the water!
3)	Keep a lookout for migrating whales August in the Whitsundays means the marine playgrounds are coming to life, with the magnificent humpback whales making their annual migration from the chilly Antarctic waters to the tropical Australian waters to breed! If you need another remarkable reason to book a day or overnight tour of the Whitsunday Islands this is it - remember to grab your binoculars and keep your eyes peeled this whale season!
4)	Take advantage of the cooler weather Don’t worry about planning your Whitsundays adventures for the morning or afternoon to avoid the balmy humidity… August boasts ideal temperatures for exploring at any time of the day! Stay cool and comfortable as you relax peacefully on Whitehaven Beach, walk and hike the Whitsundays national parks, and boogie the friends at Airlie Beach’s many lively bars and nightclubs!
5)	Book an overnight sailing trip! There is no better way to soak in the lush island havens of the Whitsunday Islands this August than on an overnight sailing trip! Awake to bright tropical sunshine, set sail in pristine conditions, and fall asleep cosily under the stars.
