Cairns Weather in March

March is not the best time to visit Cairns, as it falls during the hot, rainy season.

You can expect hot and humid weather with around seven hours of sunshine daily interspersed by tropical downpours that mainly fall at night. Daytime temperatures reach an average high of 30°C (86°F) with a low of 23°C (73°F) at night.

Despite the occasional rain showers, March weather conditions are still good for rainforest tours, white-water rafting, game fishing and diving the Great Barrier Reef.

March is considered low season in Cairns, with lower hotel rates and fewer visitors except for the New Year Holidays.

Note: March 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.
