Of Sydney’s weather of 27th December 1790, when the mercury hit 42.8 C (109 F), half a degree Celsius higher than last Tuesday, Watkins Tench wrote; “it felt like the blast of a heated oven”. But the extreme heat wasn’t restricted to the 27th Dec 1790. The following day the temperature again surpassed the old 100 Fahrenheit mark, hitting 40.3C (104.5 F) at 12.30pm.
