You can suffer exposure in the summertime if you're not dressed for a cool night in the mountains. It's the next best thing, where you mostly freeze, but there's no permanent damage to tissue. Less serious than frostbite is "exposure". If both are 20 km/h, you end up with an effective 40km/h wind. This also means that wind speed + your speed is a nasty effect. Since the wind rarely goes exactly in the same direction as you do, there will always be a little breeze, but you get the idea. On the flip side, if there's a 20 km/h tailwind, and you're riding 20 km/h, the effective wind speed on you is 0. I found this out the hard way about a month ago, when a balmy -12C at the house became enough to freeze a little section of skin on my forehead on a 50 km/h downhill. Is the wind speed equivalent to your riding speed?Ĭan you add headwind speed to riding speed? Can you subtract tailwind speed from riding speed? What about crosswinds?įinally, about "frostbite." Are there cold injuries that are less serious than frostbite? Should we worry about those at warmer temperatures?Wind speed is whatever speed you're moving through the wind at. I am just full of questions on this topic. I tend to err on the side of safety anyway, that's just me. *However it is very important for new winter riders to be careful and to look at a chart just to get an idea of what happens. I fine tune how warm I am by how much effort I expend when I need to. With the bicycle I find I need to have a way to adjust what I wear a little for the amount of heat I produce and the speed of the bike. I rode motorcycles in the cold and snow for decades, the wind chill factor is much worse. I bring goggles If I wear glasses if it's very cold anyway. If it's really windy I just dress a little warmer. I have a neck gaiter and I can pull it up under my goggles or glasses if I need to. I finally stopped even thinking about wind chill a few years ago and just made sure there is always a way to cover all my skin. Over the years I learned about what to wear for what temperature, which makes it easier to get dressed before a ride. I calculated wind chills with a wind chill chart etc.I have a thermometer that has a wind chill chart on it. I rode (and still do) with a thermometer on my handlebars in winter for about 10 years. I learned my lesson with a small gap between my mittens and my sleeve on a dogsled being pulled by a snowmobile when I was about 15. That's amazing about the adaptation to the cold and the different warning levels! It is important for anyone outside in the cold to understand this. It includes all sorts of charts, online calculators, scientific equations, and so on:Īnd if, for some reason, you are not familiar with the metric system. This is the entire WindChill site which Environment Canada has put together. Residents of the Arctic, northern Manitoba and northern Quebec are warned at about -50, and those of the high Arctic, at about -55." Most of Canada hears a warning at about -45. Because of this, Environment Canada issues warnings at progressively colder wind chill values as you move north. Further north, people have grown more accustomed to the cold, and have adapted to the more severe conditions. "**In parts of the country with a milder climate (such as southern Ontario and the Atlantic provinces except Labrador), a wind chill warning is issued at about -35. This little paragraph at the bottom there is interesting!! This is a chart letting you know the risk at certain temperatures and how to dress for them Note that the charts are Canadian so the temperatures are Celcius and the windspeeds are in Kilometers. These are charts letting you know how many minutes it will take to begin to develop frostbite at different temperatures and wind speeds.
