Weather hazards

Strong sunlight Medium likelihood Hide 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 Low 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.

Weather

A bright day with some good sunny spells to start then scattered showers expected to develop across many parts from noon onwards through the afternoon and early evening. A few briefly heavy showers likely with very isolated thunder possible, but many areas missing these and sunny intervals will continue on and off.

Chance of cloud-free mountain/hill tops at 800m

70% till noon with some good gaps in the cloud and only odd banks of cloud near summit level. However during the afternoon clouds will increase with a 40 or 50% chance of clear summits with occasional cloud cover around the 750-900 metres level. Brief banks lower 600 metres in showers.

Visibility

Generally good with mid distance hills discernible, however during showers often moderate with neighbouring slopes briefly diffuse. On higher slopes some patchy foggy with brief navigational issues above 750-900 metres as showers move through.

Met Office Aberdeen meteorologist's view

In the sunny spells it will feel reasonable even on higher slopes, the windchill only notable when in cloud and under showers on summits. Some gusts 40mph early hours Saturday on summits.

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).
