Biggest range of temperatures I've experience have been
Warmest 46°c Turkey very dry heat.
Coldest -26°c Northern Finland, strange cold as no moisture in air so no damp feeling.
Most uncomfortable when I was stationed in Belize in the early nineties only low to mid 30's but massively high humidity as on the edge of jungle, took about 6 weeks to get used to it.
Can't imagine what 50°c and above feels like
The temps only climb that high when there is no humidity to speak of, everything that can't get out of the sun, simply dries out.
The last hot spell we had when we lived in our house beside the Murray River, bird life that wouldn't normally be seen in the same area on the water, all gathered together in the small bay that was shaded by gum trees where we had put out floating tree branches for those that couldn't really stay in the water for a long time, could perch but still go for a dip to cool off. It was wing tip to wing tip, all packed in, yet making room for another that turned up to survive .....
In this part of the country, people couldn't survive without good air cond. Before proper heat pump air conditioning, there was always a death toll of those who just couldn't survive the extreme heat, there is only so much heat an evaporative cooler can get out of the air before it;s pumped through the house.
Now days, the community club, pubs and supermarkets, make provision for those who need shelter during the day to escape the heat. Community mini busses head out in the mornings of the days the extreme heat is expected, pick up the vulnerable, and bring them into the cool for the day, then take them back home in the evening ..... dogs and cats in carry cages, birds in cages, all gathered together in a spirit of community survival.
In the bigger towns and the city, places advertise they are open for people to escape the heat for the day, neighbours look out for one another ..... and some simply use it as an excuse to get out in the water and swim or wake board or ski or what ever .....
