Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

hazard Strong Sunlight
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.

hazard Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
hazard Poor Visibility
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.
hazard Thunderstorms
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.
hazard Heavy Persistent Rain
Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.

Summit specific forecast

Mountain summit forecast map

This weather forecast area covers much of the southern and eastern Cairngorm National Park, the Aberdeenshire hills and Angus hills and includes the Balmoral Estate, Scottish home of the Royal Family since 1852. Lochnagar, with its magnificent northern corrie, is very popular among walkers and climbers and Mount Keen is the most easterly of all Munros (Scottish mountains over 3000 feet).

The Perthshire hills offer a rich variety of heather-clad hills and mighty pine forests. The River Tay flows 120 miles from its source to the North Sea and is the longest and largest river in Scotland. Loch Tay is a freshwater loch and 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 near the north shore of the loch that includes seven Munros.

The Ochil Hills are a long range of steep-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.
