Mountain weather
North Grampian Mountain weather forecast table
Confidence
High confidence for settled conditions, with light winds and sunshine for many, remaining for the weekend and early next week, the main uncertainties in the forecasts are about low cloud which looks likely to affect the northeast hills at times over the weekend. The other uncertainty is shower development, however central Scotland looks most at risk on Saturday.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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.
Mountain weather forecast
A largely dry and bright day with sunshine for many, a scattering of afternoon showers, mainly west of the A9, light winds.

Additional weather information
Met Office Aberdeen meteorologist's view
Light winds and strong sunshine at times in the west, sunshine hazy at times further north and east depending on the cloud amounts.
Weather
Some low cloud around in the north and east for the start of the day but this should burn back to the coast, although some lingering around the Speyside hills. Elsewhere a sunny morning, the warmth will trigger a few showers during the afternoon, these may be heavy and thundery at times, and are likely to be restricted to the ranges west of the A9, but it's probably worth preparing for a shower anywhere. Showers dying out in the evening with cloud likely to spread across the hills from the east during the evening.
Chance of cloud-free hill tops
60% in the east with the chance of low cloud from the north and east affecting hill tops, closer to 90% further west.
Low cloud and visibility
Lower cloud in the early morning and later in the evening is likely to spread across northern and eastern hills but will burn back for most of the day, there is a chance it will linger around Speyside for much of the day with scattered layers above 600m. Further west most summits will be clear for much of the day with very good visibility, although in a heavier shower cloud bases may drop to 700m temporarily as the shower moves through. Visibility in a shower may drop to moderate for a time. Visibility perhaps moderate or poor visibility at times for the Moray hills like Ben Rinnes.
Mountain weather information
Weather
Mostly dry on Sunday but perhaps more in the way of cloud around the hills, cloud perhaps thick enough to give some drizzle, especially around the Northern Cairngorms in the morning, best of the brighter conditions further West towards the likes of the Ben Alder area. Brighter spells developing in the afternoon.
Chance of cloud-free hill tops
50%, cloudy at times for summits further east.
Maximum wind speed expected
Northeasterly 5-10 mph.
Temperature
- At 800m Plus 6 rising to 11 Celsius
- Glen Plus 10 rising to 16 Celsius.
- Freezing level Above all summits.
Low cloud and visibility
Scattered layers of cloud above 500-600m in the east, further west cloud will be patchy above 700m. Visibility poor at times in the east, especially around Moray. Good or very good in the west.
