Southwesterly 30 to 50mph, speed tending to rise during the day, some notable strong gusts especially north/east Cairngorms.

A little patchy rain or drizzle spilling in from the southwest at times, amounting to very little over several hours, especially in the east where more often dry. With time, risk of more persistent rain setting in near and west of the A9.

Cloud on the hills?

Extensive higher areas

Shrouding most high terrain all day, lowest most persistent cloud bases near Drumochter to Glen Garry, at times to mid-slopes. Capping most of Cairngorm plateau, some breaks above 1000m north.

20%

Sunshine and air clarity?

Glimpses of sun mostly toward Glenmore and locally Deeside. Visibility good below cloud, reducing in rain.

Westerly 40 to 50mph with stronger gusts possibly early in the day, then moderating to typically 25-35mph.

Challenging conditions at first lessening, but staying blustery with buffeting gusts on exposed terrain, considerable wind chill.

How Wet?

Intermittent rain

Showery rain spreading from the west, may become more frequent over a few hours with scattered heavier bursts mainly afternoon.

Cloud on the hills?

Confined to high tops with breaks

Most cloud above 900m, often confined to 1100m or higher further east with breaks over higher summits at times. Lowering patches especially in west in rain.

Chance of cloud free Munros?

50%

Sunshine and air clarity?

Occasional sun, mostly toward east. Visibility often very good, reduced in showers.

7 or 8C, small change then trending slightly cooler later in daytime. Feeling like -3C in the wind.

Planning Outlook

Staying unsettled during the next week to 10 days as westerlies prevail - areas of low pressure passing north of Scotland with frontal systems bringing frequent rain, wettest over western mountains in Scotland. Often windy, gale-force westerly winds for periods over higher terrain. Fairly warm and humid on Monday, then on the cooler side for several days, with considerable wind chill on the mountains. Higher pressure and better weather tends to expand further north later in month.
