High Wind in the Mountains and the Impact on Hikers

High wind in the mountains can be a real game changer, it can have a profound effect on safety and morale. It can make it feel much colder than it actually is (wind chill effect), and can be unpredictable in direction and speed.

Wind speed in km/hr Effect on you What should you do?
Less than 20 Negligible Continue as planned
20-30 Unlikely to affect your balance or control. At these windspeeds in winter a temperature of 0C will have an equivalent wind chill of around-10C. Add an extra warm layer.Prevent small items from blowing loose.

Goggles will be useful in winter conditions.

30-40 You will begin to feel the buffeting effect of the wind. Progress into a head wind will become more laboured. It will be harder to maintain your balance when walking. Keep way from steep and exposed ridge lines. Secure your map and tie down loose clothing and secure toggles to prevent them whipping around.
40-50 Walking will become more difficult. Energy output will be significantly increased. Expect a greater risk of being blown sideways and off balance. Consider changing your route to avoid a head or cross wind. Be prepared to shorten the day. Check companions for signs of hypothermia and frost nip, particularly in winter.Navigation will become more difficult.
50-60 Walking will become very challenging. There is a strong chance of being blown off your feet. Link arms with weaker members of your group. Try to move between the worst gusts. Get off the hill by the safest and easiest route keeping away from steep windward drops.
60-70 As above If you must venture out in these conditions then keep to the valley floor.
