When to go

Best time to visit Townsville

Townsville is tropical with a dry season that generally runs May to Oct and a wet season that generally runs Nov to Apr.

Best overall window

May to September

Dry season pattern, lower rainfall, steadier weather. Water often around 24°C to 26°C and trade winds can sit near 20 km/h.

Outside that window

Wet season storms and cyclone risk. Water is warm (often near 28°C to 29°C) but visibility can be patchy and stinger protection is important.

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.
