Well, the outside temp. will never precisely feel like the “real” temperature considering sun, humidity, and other factors, but in the controlled environment of the inside I can often feel the difference of a degree of Fahrenheit. So wanting more accurate readings of outside temperatures may be somewhat a psychological thing.
However, if it goes from 64°F to 65°F, it can be easily seen to be getting hotter, and of course, the reverse. It takes longer to note these changes when using Centigrade as none of my temperature readings used decimals.
Throughout the summer months here at the lab (we’re in the SoCal high desert), many days require limiting the outdoors work hours for our techs. Sometimes work even gets canceled due to the heat. Those having to work with little to no shade use wetted down cooling hats. They swear by it. Some of the techs use good quality spray bottles for fine-misting water onto themselves. Evaporative cooling. Something to consider if you’re in a position to safely spritz water on yourself while working.
Don’t forget to also thank most of your friends and neighbors; they gleefully drove around in their cars, SUVs and pickup trucks after voting for politicians that kept gas prices low, used lots of fossil fuel generated electricity and did all the other things serious environmentalists warned about as being contributors to global warming.
