* Cairns has a wet and a dry season: "summer" is the wet season, "winter" the dry season.
🌧️ Wet season (December to March)
31–32 °C (88–90 °F)
Cairns has no real summer or winter; the climate is tropical. The wet season is very hot, with extreme humidity and frequent monsoon downpours. Wear only the lightest loose clothes in thin natural fabrics, shorts and sandals, plus a light rain poncho. Warm clothes are not needed outdoors at all; at most a thin cardigan for buses and shopping centres where the air-conditioning is freezing.
☀️ Dry season (June to August)
days 25–26 °C (77–79 °F)evenings 17 °C (63 °F)
The best time in Cairns: the humidity drops and it hardly rains. People keep wearing summer clothes: shorts, singlets, T-shirts and summer dresses. Evenings are cooler, so for dinner outdoors a light long-sleeved shirt or a thin cardigan is enough.
🍂🌱 Autumn and spring
hot
The months in between, when the humidity is either building up or easing off. It stays hot, and you only need summer clothes.
