Weather stations in Sydney, Australia recorded the hottest December night in 159 years on December 13 and 14, 2016, breaking all weather bureau records for the city.
The lowest temperature reached was 27.1 °C (80.8 °F) at Sydney Observatory Hill between 09:00 AEDT on Tuesday, December 13 and 09:00 on Wednesday. The previous record was 26.3 °C (79.3 °F) set in 1868.
According to the BOM, the overnight heat also makes it the second hottest night on record for any month of the year.

This heat will not last for long, though. Wednesday started hot, but clouds soon arrived over the region bringing light rain and temperature drop.
At 18:00 AEDT it was still 31 °C (87.8 °F) in the city, but the temperatures are expected to drop down to 17 °C (62.6 °F) or even lower during the night.
