What is the Ultraviolet (UV) Index Forecast?

When is the stinger season?

Stinger season or jellyfish season is generally between November and May in Cairns and Port Douglas. From November it is sensible to wear stinger suits in the water, as box jellyfish and Irukandji (the smallest of the box jellyfish family) can be deadly. Beaches are also lined with stinger nets. Out on the Great Barrier Reef the risk of marine stingers is low, however stinger suits are recommended and available for hire on tour boats.
