Latest detailed observed forecast and environmental conditions
Over summer, we monitor the health of the Great Barrier Reef to see how it's faring, as this time brings an increased risk of extreme weather, particularly heat waves, cyclones and flooding.
A detailed overview of the environmental conditions on the Reef is available below, and an overview of current conditions is also available.
Updates on current conditions are provided as part of our Reef Health Incident Response System.
Update 2: 12 January 2018
Forecast from the Bureau of Meteorology
Sea surface temperature (°C)
As of 9 January 2018, sea surface temperatures were generally average throughout the Marine Park, with the exception of the Far Northern management area and some inshore areas throughout the Park which were 0.5-1.5ºC above average.
Since the beginning of December, between 10 and 20 degree heating days have accrued throughout the Marine Park. 30 degree heating days have accrued in the inshore Townsville region.
Accumulated heat stress, in the form of degree heating days, is calculated by accumulating positive daily sea surface temperature anomalies.
This is relative to the appropriate long-term monthly mean, for 1 December to 31 March.
Degree heating day values can represent a broad range of thermal stress; e.g. three days at 1°C above the local long-term average results in the same degree heating day value as one day at 3°C (Bureau of Meteorology).
No cyclones are currently affecting the Great Barrier Reef.
Between 1 October and 31 December 2017 rainfall levels in the Great Barrier Reef catchment were generally average. Exceptions were the Cape York region which received below average and southern Queensland which received very much above average (Bureau of Meteorology).
No flood plumes currently affecting the Great Barrier Reef.
