West to southwesterly 35 to 45mph, very gusty in places, the strongest gusts not confined to highest summits.

Blanket cloud across the hills, foggy from lower elevations upward near the west coast likely all day. Some breaks may emerge at varied levels further inland and east, but rarely clearing any summits.
Chance of cloud free Munros?
10%

Planning Outlook
Improving on Sunday as gale-force winds on Scottish mountains gradually lessen and showers become fewer. Warm and humid into early next week, on Monday extensive low cloud and drizzly rain particularly in the west. High pressure to the south will generally dominate the extended outlook particularly for England & Wales with more often drier and warmer conditions through late September into early October. Fine weather likely extends across Scotland for periods too, but a more changeable autumnal mix may continue especially further northwest with rain and stronger winds at times.
