Great Barrier Reef Marine Park annual climate and rainfall pattern

At Great Barrier Reef Marine Park’s sea-level point, the 1991–2020 mean-temperature range runs from 22.79 °C in August to 27.92 °C in February, with monthly average minima and maxima framing the thermal variation. Average daily precipitation is lowest in September at 0.28 mm and highest in February at 6.07 mm; this point climatology does not describe every reef or predict marine weather.
