The Bureau of Meteorology is predicting a maximum of 37 degrees on Saturday and a shower or two.
BOM is tipping a “medium chance” of showers, most likely later in the evening ahead of a 21 degree max on Sunday.
Sunday’s forecast includes “showers easing”.
Adelaide has a reputation as one of the toughest physical tests for drivers, with extreme heat a reoccurring factor over its 25-year history.
The mercury hit 35.5 degrees on the Sunday two years ago, after which event organisers re-installed shade on key grandstands that had not been erected for the event’s comeback year.
The hottest Adelaide 500 race day on record came back in 2019, when temperatures reached 41 degrees amid a sustained heatwave during the then-March event.
Supercars’ hot weather policy requires driver cooling systems to be fitted and operational if the forecast temperature is above 32.9 degrees.
Wet weather impacted the event on Thursday last year before conditions fined up.
The last wet Adelaide Supercars race came in 2016, when a multi-day heatwave was broken by a deluge just prior to the Sunday race start.
