The weather of the Great Barrier Reef changes seasonally and it is usually the case that the weather on land is quite different to out at sea. Don’t be deterred by the weather forecast for local towns and cities when booking a reef trip, rather ask your local tour booking agent or call our friendly office, on +61 7 4051 5777, for accurate information on the conditions over the reef.
