Not only is it summer in just the Northern Hemisphere but in warm climates like the US south most people stay inside during the hottest part of the day.

I live in Texas. Going outside at 2 in the afternoon is certain death! Lol. I used to live in Minnesota and spent every single Summer day outside and every Winter day inside. Now I spend every summer day inside unless I can go to the beach... and we don't have any in Dallas. I have to drive 4 hours to Galveston to swim in the Gulf or 3 1/2 hours to Austin to swim in their beautiful lakes. Gee Max... Dallas is so wonderful.
