    Note: The near-real time GBR1 and GBR4 models (including hydro, river tracer and BGC) are currently paused at December 17th 2023 due to infrastructure damage from the recent flooding events around the Daintree River region (see here). These floods have damaged the real-time river temperature and flow sensors across surrounding catchments, and Queensland government is working to recover and restore these as quickly as possible. We will provide further updates when available.


    This page shows the daily minimum, maximum and temperature range on the Great Barrier Reef based on the 1km eReefs Hydrodynamic model. This is an experimental product that is intended to help investigate whether daily temperature range is a useful indicator of resistence to coral bleaching.

    Erratum

    From 28 Dec 2014 - 29 Dec 2014 and from 1 Dec - 10 Dec 2021, the forcing data for the GBR1 eReefs model was incorrect due to a process failure while extracting the relevant ACCESS data. This resulted in static tides and winds during this period, leading to incorrect model outputs during Dec 2014 and 2021, with some carry over error into Jan 2022. This forcing error led to a decrease in water mixing resulting in the temperature building up several degrees hotter than it should and to the flood plumes from the Fitzroy and Burnett moving in the wrong direction.

    CSIRO are correcting this problem by re-running the model from Dec 2021 for several months to replace this section of the data. This warning will be updated when this change has been made.
