The first thing I look for on the mountain weather forecast is the wind direction and speed to ensure that I use the wind to my advantage. For example, if the wind is forecast to come from the south-west, then I want to ensure that when I am on the exposed higher ground I have the wind behind me, helping me along, rather than hindering progress. This is particularly important if precipitation is also forecast, as it’s extremely unpleasant with rain or snow lashing in your face carried on a 30 miles per hour (mph) wind. Far better to have the weather on your back. In addition, battling into a strong wind is very energy-sapping and exposure to wind will be a significant factor in the onset of hypothermia.

Take a look at the table below to check out how different wind speeds will affect progress and balance and remember that wind will always increase with altitude so it’s a good idea to check the mountain-specific forecasts which will give detail of wind speed at different altitudes. The new Met Office Mountain Forecast launched in 2017 will provide both the gust and the average (mean) speed in mph at 300, 600, 900 and 1100 meters above sea level.
