The city's temperature soared as punters descended on Morphettville for the running of the Adelaide Cup.
There was plenty of demand for cool drinks and most racegoers sought out any available shade.
South Australian Jockey Club chief executive Brenton Wilkinson said everything possible had been organised to help people manage in the extreme conditions.
"We've hired as many fans and misting fans that were available in South Australia but, as we're all aware, there's a lot of events on at the moment and some of this equipment gets a bit short," he said.
"We've taken all the measures that we can, got plenty of bottled water on course but on course there's free water fountains around the place for plenty of drinking water.
"We've got sunscreen available for free at all the bar outlets. We want everyone to put plenty of sunscreen on and keep themselves in the best shape they can."
Veterinarians kept a close watch on the horses for any signs of distress in the searing conditions.
The temperature went beyond 38 degrees Celsius as the main race of the day approached.
The fashions were on show, as always, and the Cup itself was run just after 4:00pm, for those who could be bothered taking an interest in the horses themselves and leaving the air-conditioned bars for the grandstands.
Many opted just to watch the main race in the cooler parts of the complex, on one of the available screens.
Tasmanian galloper Norsqui took out the Cup, ahead of Waratone and Dame Claire.
Tasmanian trainer Walter McShane announced his retirement after the win.
"They've been trying to pension me off for a while. I have a son who is taking over the training from me and he's pretty keen to get a foothold so I've got to relinquish to a certain degree, but I don't like doing it," he said.
