Weather hazards

Gales High likelihood Hide detail

Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult to follow accurately.

Strong sunlight High likelihood Show detail

Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.

Poor visibility Medium likelihood Show detail

Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.

Thunderstorms Low likelihood Show detail

Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.

Separated from the Grampians by the Great Glen the region includes Sutherland, Ben Wyvis, Wester Ross, The Cuillin, Glen Affric, Glen Shiel and Knoydart.

The Cuillin Hills on the Isle of Skye are among the steepest mountains in the UK and include 15 peaks above 3,000 feet (900 metres). There are two main ridges; the magnificent Black Cuillins and the Red Cuillins around Loch Coruisk to the south.

Torridon has some of the most spectacular mountain scenery in Scotland which includes Beinn Eighe, a long ridge with many spurs and summits, two of which are classified as Munros. Beinne Eighe also includes Britain's first ever national nature reserve where you may spot golden eagles, buzzards, pine martins and wild cats on your travels.
