In reply to Jürg Wyttenbach's message of Mon, 26 Oct 2026 18:03:10 +0100: Hi Jürg,
I agree humidity is also important, which is why large coastal cities near an open body of water may be most at risk. Also while 50C is survivable with dry air, plenty of liquids, and good aircon, 60-70C on a humid day with no aircon isn't, especially if the water coming out of the cold water tap has the same temperature as the water coming out of the hot tap. ....perfect storm.
