I live in a mediterranean country where those high temps are a fact of life all along summer, every year.
Nobody dies here due to heat, as things like "drinking" are already instinctive. Also things like avoiding exposure to the direct heat/radiation of the sun and seek some shelter during the hottest hours of the day are well heeded.

Almost every place is air conditioned, cars too by law.

Many years ago while serving in the desert, we were told to drink not less than 20 liters a day. This helps if temperatures are "reasonably " low. A group of people was cooked while crossing at midday a granite rock area, which was at some 70 Deg C. That's heat shock and not much could be done to save them.


This year was a tougher one- I perceived more hotter days than in previous years. In our shop (a foundry) we had more damaged electric and electronic components due to the heat than in previous years.

The weather is going downhill and gathering speed- I think.

Take care.
