Wind is one of the natural elements that can make a mountain hike particularly uncomfortable, or even dangerous if you are not prepared. This often underestimated phenomenon can affect your comfort and safety, especially if you hike on exposed terrain or at high altitude. It is therefore essential to take steps to protect yourself effectively against the wind on your mountain outings.
Understanding the impact of wind when hiking
Wind directly affects perceived temperature. Our body produces a thin layer of warm air on the skin's surface that acts as a thermal barrier. When the wind blows, it disperses this warm air layer, exposing us to colder outside air, which creates a sensation of heat loss. This can cause rapid body cooling, especially when humidity is present, increasing the risk of hypothermia.
The link between wind and perceived temperature is direct: the stronger the wind, the lower the perceived temperature. For example, if the actual temperature is 10°C and the wind is blowing at 30 km/h, you will feel a temperature of 6.6°C. This difference can be even more pronounced when outdoor temperatures are already cold. Wind is therefore a factor not to be overlooked when assessing safety conditions on your hikes.
Preparation and planning before the hike
Before heading out, it is crucial to check the weather forecast to find out wind speed and direction. This information will help you prepare better. In the mountains, wind can blow unpredictably, especially in open areas or on ridges.
It is also important to choose a route that takes into account wind-exposed areas. When taking breaks, favour natural shelters such as rocks, embankments or clumps of trees to shield yourself from the wind. Don't underestimate the need to find a sheltered spot, even if it means walking a little further to find better cover.
Choosing the right clothing to protect yourself from the wind
Clothing plays a key role in protection against wind. It is essential to layer strategically:
- First layer: it must be breathable to wick away body moisture.
- Second layer: this acts as insulation and helps retain body heat. Go for a warm, technical fleece jacket.
- Third layer: this is the most important one against wind. This outer layer, typically a softshell jacket or hardshell, must be designed to provide wind protection while still allowing the skin to breathe.
Modern windproof jackets are often fitted with technical membranes that effectively block wind while remaining lightweight and packable. Choose a jacket suited to your activity level that can be easily stowed in your pack when conditions improve.
Protecting the head and hands
A large amount of body heat is lost through the head and hands. It is therefore crucial to protect them well against the wind. A wool or insulating material beanie is ideal for retaining heat. A windproof cap or hat can also be useful for shielding against gusts and preventing sweat from running into your eyes.
Don't forget your hiking gloves, especially if you are walking in cool conditions. Windproof gloves that insulate from the cold while offering good flexibility are ideal for protecting your hands and maintaining a firm grip on your hiking poles.
Adjusting your gear during the hike
During your hike, it is essential to adjust your gear according to the conditions. In particular, make sure your clothing is well fitted to prevent wind from getting in. Tuck the bottom of your trousers into your shoes or socks, close all zips and use velcro fastenings to keep out unwanted draughts.
Also remember to adjust your shoes and socks to avoid any friction or discomfort that could be amplified by the wind.
Protecting the other members of the group
If you are hiking in a group, make sure the other members are also properly protected from the wind. In the event of injury or fatigue, wind can accelerate body heat loss, making the situation even more critical. It is therefore vital to set up a bivvy in a sheltered spot, provide appropriate clothing and ensure everyone stays warm during breaks.
Wind on a hike may seem harmless at first glance, but its effects can be devastating if you are not prepared. By planning your route, choosing the right gear and staying alert to your surroundings, you can significantly reduce the impact of wind and fully enjoy your mountain experience. Kit yourself out properly, stay vigilant, and don't forget to protect yourself and those around you from the effects of wind to ensure a safe and enjoyable hiking experience.
