It was -13 with a wind chill of -40. It counts if you're working in it lol

    -13 with wind is definitely an obstacle and can be downright dangerous if you're not prepared, but I can't help but just shake my head when people (weather forecasters, mostly) report absurdly low temps without informing people that they're talking about the windchill.
    Windchill is a scientifically "fuzzy" number that has little value besides getting ratings for the Weather Channel. Humidity, sunshine, precipitation, level of physical avtivity/movement, clothing choices, etc. all have similar, if not much greater, influence on perceived coldness.
    I went out snowshoeing in a blizzard last night for a few hours. It was 0F with 45 mph wind. If I'm dressed appropriately, I'd take that (-35 windchill)
any day over plain ol' -35. At -35, holding anything metal, even with thick mittens on, is soon painful. It's hard to keep warm with physical activity because breathing -35 air starts to hurt.
    When I got in from snowshoeing last night, my lips and nose were red and swollen from frostnip - mainly because all the snow made my facemask keep freezing to my face. But I know that three hours out in real -35 weather would have been a different story. Â
    Don't get me wrong, working a shift outdoors in below zero weather, doing what you do, is badass. I can't imagine it's easy to keep your hands warm while handling steel piping and levers and whatnot. But windchill doesn't equate to real temperature. There are just too many other variable left out of the equation. It's just a number weathermen came up with to tell us how they think we will feel.
