The UK is experiencing stronger and more frequent storms, particularly during the winter. There is plenty of warning and advice available for mountain hiking in snow, ice and mist, but wind can be an overlooked hazard. Here’s a look at the risks of walking in high winds, how to accurately judge windspeeds, and some tips for dealing with stormy conditions.
What are the hazards of hillwalking in high winds?
When a strong wind picks up in an exposed location, it presents a number of risks, including the following:
Being blown over and injured—A strong gust of wind can knock you off your feet, and may cause bruising, fractures, sprains or head injuries. Forceful winds can also make it difficult to get up or move forwards.
Being blown off a drop—On exposed ridges, being blown over a cliff can cause serious injuries or even be fatal
Poor visibility—Winds can whip up snow or rain, making it hard to follow a path or avoid hazardous drops
Impaired navigation—In high winds, navigating can be difficult as tools are unsteady and it’s possible to get blown off course
Losing kit—Strong winds can whisk away loose items such as hats, gloves, and maps
Hypothermia—constant exposure to cold winds increases the risk of hypothermia, frostnip and frostbite
How to judge to risk of the wind speed
It can be difficult to accurately gauge the wind speed in the hills. Storm forecasts usually give the highest windspeed expected in exposed areas, and most people assume that these speeds apply to their usual lower locations, and therefore underestimate their power. This can lead to misjudgements and walkers venturing out in dangerous conditions.
Typically, walking in wind speeds of over 25mph is difficult; and approaching 40mph or above is very dangerous. The risks also vary depending on build and bodyweight: smaller lighter people are more at risk of being blown over than heavier people. The type of wind is also a factor: a strong but steady wind is easier to walk in than inconsistent gusts.
Tips for walking in high winds
In the first instance, keep an eye on the forecast and avoid exposed routes such as the Aonach Eagach ridge if gales are forecast. If there is a strong breeze, try to walk into it on your outgoing route, so that if you need to turn back it’s easier. Have an alternative route planned and be ready to turn back if you or any members of your party are struggling.
Keep an eye out for each other; smaller people may need support in strong gusts. Walking poles can provide more stability. Take smaller steps and angle yourself slightly so that you are not facing a strong wind head on. In very forceful winds, crouch down or crawl to avoid being blown over.
Dress in warm layers to counteract the wind chill. Avoid any loose or unsecured clothing that could get blown away, and carry spares of essentials such as hats and gloves.
