South Australia is facing its first ever November heatwave. November is typically springtime and the heat of summer commences from December to February in Australia.
Yesterday record November temperatures were reached in most of the state. The hottest city was Ceduna reaching 47 degrees Celsisus, more than 20 degrees above the usual November temperatures. The capital of South Australia recorded 43 degrees.
What constitutes a heatwave? It's a number of consecutive days over a high temperature (although the baseline varies). Adelaide has had 13 consecutive days over 33 C before, and 6 consecutive days over 40 C - both of these were in January. Adelaide's previous record heat wave for November was 115 years ago, with four consecutive days of temperatures over 35 C degrees. This year the new record is 13 consecutive days over 35 scorching degrees. Today the rain has arrived breaking the heatwave and bringing cooler temperatures (an estimated 27 degrees).
