Just input two numbers: T \footnotesize T T — Temperature — air temperature or dry-bulb temperature is the temperature given by a thermometer not exposed to direct sunlight. Being an inanimate, non-living thing, water is not impacted by wind chill.The best temperature for a typical pool rests between 78 to 86 degrees Fahrenheit.The snow cover will actually make both nights and days cooler, by slightly different mechanisms: Daytime: Snow is white, and so reflects more sunlight than the ground underneath it would, which lowers the amount of warming of the ground, and thus the air. Let’s explain the differences between what we now know about cold tires and hot tires.
