I thought I knew what hot was until I went to Cambodia last year. OMG! This was during the "cool season", in November, when the morning low was about 85 and the midday was about 105.
So in reference to the above - and I'm really not kidding - some people were wearing sweaters because it was 'too cool'.
Sounds like a couple from church who spent a couple years in Burkino Faso. When they came back one August they were wearing wool coats because our sweltering 85F heat wave was cold to them...
