The Great Barrier Reef has a tropical climate, with average temperatures in summer of between 24 and 33 degrees Celsius, in winter 14 to 26 degrees. Being a wet tropic climate, there are only 2 seasons, 'the green' and 'the dry'.here is the Great Barrier Reef? The Great Barrier Reef, one of the natural wonders of the world, begins just off the coast of Bundaberg, 368 kilometres north of the state capital, Brisbane, and extends over 2000 km north to western Papua New Guinea.
Impacts of sea level rise on the Reef. Rising sea levels will be significant because much of the Great Barrier Reef coastline is low-lying. Predictions of a future increase in sea levels are highly variable and range from 0.68m across the Great Barrier Reef Region to a global increase of up to 0.9m by 2100.hanges in sea levels from temperature increases are time-dependent and uncertain, because they are partly linked to the collapse of the Earthâs great ice shelves. Since 1959, records of variations in sea levels for Townsville, in north Queensland, show an average increase of 1.2mm per year.
