it is still Spring in Australia but yesterday New South Wales experienced its highest November temperature on record and last night’s temperature was the highest over-night temperature experienced for November, too.  . 

According to the Guardian newspaper:

Sydney has sweltered through its hottest November night since records began more than 160 years ago before temperatures again climbed above 40C in the city on Sunday ahead of a cool but gusty change.

The temperature dropped to just 25.3C at 1.09am on Sunday at Sydney’s Observatory Hill and rose above 30C shortly after 4.30am. The previous record for the warmest November minimum temperature was set in 1967 at 24.8C.
