It's official, much of South Australia and Adelaide is in its first November heatwave, and there's little relief ahead. Adelaide residents have endured five consecutive day of 35 degrees, something that no living person has experienced before in the city. The last three days have all exceeded 38 degrees, something achieved only three times before in November in 120 years of records, in 1922, 1984 and 1888. A new record should be set tomorrow, its fourth consecutive November day above 38. A cooler change is not due until at least Sunday afternoon, so this heatwave will almost certainly extend to eight days above 35 and possibly six days above 38. The change will only be weak, meaning it will rapidly heat up to the mid-to-high 30s next Wednesday and Thursday. Thankfully, a cooler change due late next week should be decent enough to keep Adelaide below 30 for several days. Almost none of the inland has been left untouched by this relentless heat which has been record-breaking in many places. Kyancutta has had five days-in-a-row above 40 degrees, equaling its November record, set in 1938. Murray Bridge just set a new record with six 35-degree days in succession.
