Daytime highs range around 31°C in January and slide to 23°C in July. Nights rarely fall below 18°C, so you can switch heavy jackets for a light fleece at most. Humidity peaks above 80% in midsummer, but steady winds and air-conditioned cabins keep things comfortable.
Climate snapshot
Average air temperature
Sea temperature
The water is about 28°C at the start of the year and cools to around 23°C by mid-winter, still warmer than most hotel pools. In the cooler months, visibility improves to over 20m, making it great for reef photography and spotting reef sharks in the sand channels.
Rainfall patterns
Roughly 60% of annual rainfall lands between January and March, in short tropical bursts rather than day-long drizzles. Pack a lightweight dry bag for electronics and a travel umbrella that is a must.
