What's a "wet and windy" 0F? It's more or less a physical impossibility. 0F air can't hold much moisture. Also, it's not a killer.

- Timpanzee 3mo agoExperience 0F wind in central North America or Central Asia vs 0F wind on the coast and tell me it’s not different. Also, it’s killer, not a killer, as in it sucks a lot.
- strictnein 3mo agoThere's still almost no moisture in the air at 0F, no matter if you're on the coast are in the middle of the continent. The air just can't hold that much water at that temp. When it's warm: 50% humidity @ 40C: 25.43 g/kg (grams of water / kg of air) 90% humidity @ 40C: 45.78 g/kg When it's cold: 50% humidity @ -18C (~0F): 0.68 g/kg 90% humidity @ -18C (~0F): 1.23 g/kg There's just not enough there to cause any noticeable affect. But you don't have to take my word for it, the US National Weather Service agrees: https://www.weather.gov/safety/cold-wind-chill-chart https://www.weather.gov/safety/cold-wind-chill-chart "The results of the tests showed that relative humidity was an insignificant weather parameter, affecting the outcome to less than 1 degree"
