Further outlook
This evening forecast
Mostly dry with clear spells this evening with excellent visibilities and largely clear summits, particularly in the sheltered northeast towards Aberdeenshire Hills. Small chance of the odd shower. There will be some fairly extensive areas of cloud around 600-800m or so for southern aspects of most ranges apart from the sheltered northeast. Strong south to southeast winds 35-50mph, some gusts around 60mph possible at first.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

Additional weather information
Meteorologist's view
Gusts of 40-50mph over the highest summits at times will give difficult walking conditions with a risk of being blown off balance. Navigation could be challenging with energy output significantly increased when walking into the wind.
Weather
Mostly dry with variable cloud and bright or sunny spells through the day. The best of the prolonged clear spells for the Aberdeenshire Hills. Mostly cloudy in the southwest where there may be the odd shower in the afternoon. Feeling chilly at height despite the sunshine.
Chance of cloud-free hill tops
>80% northeast. Otherwise 40% morning rising to 75% by afternoon.
Low cloud and visibility
Quite extensive areas of cloud around 600-700m in the morning, gradually becoming well-broken and lifting above summits by the afternoon. Generally excellent visibilities. Best of the clearer summits in the sheltered northeast.
Ground conditions
No recent ground conditions report available.
Mountain weather information
Weather
Occasionally heavy and showery rain crossing east in the early morning. Drier for a few hours from mid-morning before another band of occasionally heavy rain crosses through the afternoon. Turning dry again by early evening. Feeling chilly on the tops in rain, cloud and blustery winds. Small chance of lightning.
Chance of cloud-free hill tops
20% much of the day, rising 70% in evening.
Maximum wind speed expected
South-southwest 35-50mph at times.
Temperature
- At 800m Plus 4C to plus 8C.
- Glen Plus 8C rising to plus 16C by day.
- Freezing level Above summits - falling to 1400m in late evening.
Low cloud and visibility
Quite widespread cloud down to 500-700m and visibilities falling poor in rain and hill fog through much of the day. Best chance of any limited clearer spells in the relatively sheltered northeast. This gradually clearing and breaking through the evening allowing good or excellent visibilities.
Ground conditions
No recent ground conditions report available.
