The water temperature of the Great Barrier Reef varies between 22 degrees Celsius and 28 degrees Celsius (71 to 82 degrees Fahrenheit), depending on the season and on how far north one travels. As the reef extends for 2300 km down the coast of Queensland, it will tend to be warmer further north.

Winter temperatures do not change dramatically, as the majority of the reef is in tropical and subtropical waters, and coral requires a constant warm temperature range.
