The Great Barrier Reef is also prone to thunderstorms and the occasional cyclone. If you want reliably good underwater visibility, summer might not be the best time as rain and storms can cause the water to become murky. It's not all bad though.
Avoiding stinger seasonWhen you snorkel on the Great Barrier Reef during May to October you will avoid the peak stinger season. This is where box jellyfish and irukandji jellyfish are around. These jellyfish are around all year, they are more common during the warmer months.
Take care when diving and snorkellingBe aware of where your fins are and avoid touching anything with them. Don't rest or stand on coral. If you must stand up, make sure it is on sand or use rest stations. Observe animals rather than handling them directly, and avoid blocking the path of free swimming animals.
