How windy? (On the Munros)

Northeast 10 to 20mph at dawn. Tending to drop further through the day, as high pressure builds overhead.

Effect of the wind on you?

Marked chill at first in the wind, but tending to become small.

Dry, bar local spots of drizzle in cloud.

Scope for some spots of drizzle from the areas of low cloud as they drift south, mainly in the morning across northern and eastern areas.

Cloud on the hills?

May persist tops north, lifting elsewhere.

Cloud drifting south in morning, covering tops above 700-900m. Bases will lift and break up, with hills likely to clear, but may be slow to clear northern tops.

Chance of cloud free Munros?

40% north, but lifting to 70% in south

Sunshine and air clarity?

Often cloudy morning, before sun breaks through, but may be limited in north/east. Visibility mostly very good or excellent.

How Cold? (at 900m)

4 or 5C at dawn, will lift to 7 to 10C into the afternoon, coolest northern hills where cloud perhaps lingers tops.

Freezing Level

Above the summits, but chilly start, with heavy dew in the glens at dawn.

Planning Outlook

High pressure centred toward the northwest this week, before building overhead again toward weekend. East to northeasterly winds prevailing, gusty for periods, easing out later in week. Extensively dry with sunshine best in west, low cloud for periods northern and eastern mountains with occasional drizzle. Still very dry underfoot with significant fire risk. Turning cooler through midweek, mountain temperatures falling, chilly into the valleys and glens pre-dawn, risk slight frost in Highland glens. Fine weather likely next weekend too; will likely begin to break down from the west into the following week, but uncertainty on timings of such a transition.
