IMHO, messages on the dash are to be taken seriously, not dismissed by a comment.
My air cooled 3.2 911 shows 10 deg F in these hot days more than when the weather is 'normal, ie an ambient of 20C or less.
As the ambient (today) is much hotter, i expect the engine temp to rise, but not to prompt alarm.
Modern cars send an alarm message to ensure all is under control. I'd wait for Wednesday, should be much cooler and see how the car responds. If the message appears, I would find a good Independent to you and seek advice.
