When to go

Best time to visit Kadavu and Great Astrolabe Reef

Kadavu is diveable yearround, but the easiest overall planning window is May to October.

Best overall window

Cooler dry season, better visibility, lower storm risk and water often around 24°C to 28°C depending month and depth.

Outside that window

Warm wet season, humid weather, water can approach 30°C, and cycloneseason disruptions are possible.

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.
