The last time I was in 50C+ heat was in the Valley of the Kings in Egypt. It was take your breath-away hot.

Last weekend the “feels like” temperature crossed the 50C boundary with the thermometer reading 45C and 45% humidity. This is what it looks like, earlier in the morning (I think the UV index is “instant burn”)

Across the street they are building a high-rise. In the middle of the day, in peak heat, they were working away.

I hope they are staying hydrated.
