When to go

Best time to visit Shark Bay (Monkey Mia)

Shark Bay is a yearround destination, but wind and swell decide how ambitious you can be on the water.

Best overall window

April - May and September - October

Milder days around 24°C to 29°C and generally lighter winds than midsummer.

Outside that window

Hotter or cooler extremes plus more frequent strong sea breezes. Schedule water sessions early and keep a backup plan.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
