What August is like in Great Barrier Reef

August is dry and reliable, with highs near 81F (27C) and water still cool, around 73F (23C). Humpback whales are in the Whitsundays, the sky is usually clear, and there are no stingers. The main catch is wind: breezier days can make outer reef crossings choppy. Crowds and prices are high but a notch below July.

It suits whale watchers, sailors, and families who want dependable sunshine. If you get seasick easily, pick a sheltered Whitsundays sail or an inshore island over a long outer reef run. Divers chasing the best visibility and warmer water may prefer September.

Make the most of August

What is especially good about Great Barrier Reef this month.

Humpbacks in the Whitsundays

Whitsundays sailing

Steady winds and dry skies make it a classic month for a sailing trip through the islands, with a stop at Whitehaven Beach.

Lady Elliot Island

At the southern tip of the reef, this small coral cay is known for manta rays and turtles, reached by light aircraft.

What to pack for August

A wetsuit for cooler water
A windproof jacket for sailing days
Seasickness tablets or wristbands
Binoculars for whales

Our timing tip

Check the wind forecast and save your outer reef day for the calmest one, using the windy days for Whitsundays sailing or the Daintree.

Things to do in Great Barrier Reef

Full guide

An outer reef day trip from Cairns or Port Douglas

The outer reef has clearer water than inshore sites. Port Douglas boats reach the Agincourt Reefs; Cairns boats cover many outer reefs. Go on a calm-forecast day.

Whitehaven Beach and Hill Inlet

Pure silica sand swirling with turquoise tidal channels. Time Hill Inlet's lookout for low tide for the famous patterns.

A liveaboard to the Ribbon Reefs and Cod Hole

Multi-day dive trips reach remote reefs few day boats visit. Dwarf minke whale encounters happen here around June and July.

Tickets and tours →

Heart Reef by scenic flight

The heart-shaped reef can only be seen from the air. Seaplane and helicopter flights run from Airlie Beach and Hamilton Island.

Tickets and tours →

Daintree Rainforest and Cape Tribulation

Ancient rainforest meeting the reef. Best in the dry season when roads and the Daintree River ferry run smoothly.

Beat the crowds

Choose September or October over July: dry-season conditions, warmer water, and fewer southern Australians on their winter escape.
Book smaller-capacity boats or a liveaboard; the biggest pontoon trips carry hundreds of passengers to the same sites.
Stay in Port Douglas rather than Cairns if you want a quieter base with quicker access to the Agincourt and Low Isles reefs.
Avoid the Easter, late June to mid July, late September, and Christmas to January school holiday periods when Australian families fill resorts.

Know before you go

Reef trips operate year-round, but cyclones and strong winds can cancel departures on short notice, especially from December to April.
In stinger season, coastal beaches in tropical Queensland rely on stinger nets for swimming; some nets are removed in heavy weather.
The Daintree region's roads and river crossings can be affected by flooding in the wet season.
Reef tours include the Environmental Management Charge (the reef tax), which funds reef management; it is collected by operators.
