The actual nearshore temperatures may vary by several degrees and this can also be heavily affected by weather. Strong winds can cause cold, deep waters to replace the surface waters that had been warmed by the sun, and heavy rain can also reduce the temperature of the sea surface temperature as well.

Great Barrier Reef map and nearby water temperatures

The highest temperature in Australia today is 28.92° C (84.06° F) in Weipa. The lowest is in Austins Ferry, where the temperature of the water is 14.05° C (57.29° F).

Why measure sea surface temperatures (SST) in Great Barrier Reef?

The ocean covers about 71% of the Earth's surface, and scientists record the sea surface temperature (SST) of locations such as Great Barrier Reef because they want to understand and learn how the ocean communicates with the atomosphere of Earth.

SST is one measure that provides information on the global climate, and it can be used to predict the weather in Great Barrier Reef as well as atmospheric model simulations and to study marine ecosystems in the area.

Data source and citation

Raw data for the calculations made to find the sea surface temperature in Great Barrier Reef comes from the National Oceanic and Atmospheric Administration (NOAA) and their 1/4° daily Optimum Interpolation Sea Surface Temperature.

The water temperature data is constructed by combining observations from different platforms (satellites, ships, buoys, and Argo floats) on a regular global grid. A spatially complete sea surface temperature map is then built by interpolating to fill in gaps in the data.
