Cairns Weather in December

December is a good time to visit Cairns, although it falls during the wet summer season.

You can expect hot weather with around eight hours of sunshine daily and rain showers that mainly fall at night. Daytime temperatures climb to a high of 31°C (88°F) with a low of 23°C (73°F) at night.

December weather conditions are good for rainforest tours, white-water rafting and are ideal for game fishing and snorkelling or diving the Great Barrier Reef.

December sees hotel rates drop as the low season begins.

Note: December falls within the so called ‘marine stinger season’. While it is rare for anyone to get badly stung, it’s probably advisable to swim on beaches with swimming enclosures; all beaches in and around Cairns have small, netted enclosures for swimming.
