We had a swamp cooler in NM. It was not a very good way to keep the house cool. On the contrary. We keep our air at 80 or above in Arizona. With temps as high as they are this week, our a/c would be running around the clock. Well, with night time temps I n the 80s, it is running constantly. We could not do this in a humid environment. But I am guessing that Afghanistan is not humid.
Our friends with swamp coolers in this area hate them.
I have to keep a cool mist humidifier running when it is so hot and dry outside. It says to only put cold water in the machine. There is no such thing as cold water at this time. The water out of our taps is very warm to hot all the time. It does save on the gas water heater.
At the moment (noon), Kabul has 81°F and 23%, wind 16 mph.
My gran had one in Truth or Consequences, NM and I spent all my summer vacations there as a kid. Since I hate hot and humid with a passion (Texas), I loved spending my summers with her and I don’t recall it ever being that bad even with the swamp cooler.
Of all the places I’ve been, Texas and Florida are the worst for hot and wet.
In fact, I’ve been giving thought to moving back to T or C one day...spent the happiest days of my life there. And I’d love to end my days in a milder climate.
