Weather hazards

Severe chill effect Medium likelihood Hide detail

Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.

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.

Gales Low likelihood Show 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 Low 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.

Includes South and East Cairngorms National Park, Aberdeenshire and Angus hills, Ben Vrackie, Ben Lawers, Loch Tay and Ochils

The Ochil Hills are a long range of steeply sided, round topped hills, stretching 25 miles from the Firth of Tay to Stirling. There are many peaks over 600 metres offering splendid views across central Scotland and to the north, with Ben Cleuch the highest at 721 metres.

Loch Tay is a freshwater loch in the central highlands and is around 15 miles long. At around 150 metres deep it is one of the deepest in Scotland. At 1,214 metres Ben Lawers is the highest point along the ridge on the north shore that includes seven Munros (mountains over 3,000 ft).
