Is this combined with high humidity? Do people’s homes have a/c’s?
I live in the west and temps of 90 degrees are not uncommon - but then we all have a/c’s.
In Northeast urban areas if you drive down the street you will see thousands of individual room air conditioners sticking out from the windows of apartment buildings.
If you look more closely you will see a lot of rust on those units.
Many of them are old and break down during extended periods of high heat and humidity.
The record for the date in NYC is 99, the actual temperature not the imaginary concocted “real feel”
