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

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.

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

The overall row stays visible so you can compare it against the currently selected scope.
