Summary for all mountain areas

Broadly showery, with the showers tending to transfer inland (from western hills) during the day. However, as a front approaches western Scotland, showery rain will become frequent here later in the day, and across the Highlands, upland winds will later approach gale force.

Headline for West Highlands

Increasingly windy, and later wet.

How windy? (On the Munros)

South to southwesterly, 30mph, but into afternoon, from northwest strengthening 35 to mostly 40mph.

Effect of wind on you?

Likely to impede walking across the hills before later making walking increasingly difficult.

How Wet?

Showery; small risk lightning

Areas of showers, most frequent on western mountains morning, but spreading increasingly inland. May later afternoon and evening from the west merge to give an hour or more of constant rain. Small risk thunder.

Cloud on the hills?

Varied; extensive west

Rarely if at all clearing higher western areas and dropping below 500-600m in rain, particularly later afternoon. Elsewhere, breaks to 900 or 1000m, and Near Loch Treig and near/north of Glen Spean, breaks above 1100m, though may deteriorate later in rain.

Chance of cloud free Munros?

Less than 10% west to 60% near/north of Glen Spean

Sunshine and air clarity?

Glimpses of sunshine, mostly well inland. Often foggy higher tops, but below cloud and away from rain, visibility excellent.

How Cold? (at 900m)

6 rising to 8C

Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Saturday 29th August 2015

A lengthy showery period of weather over the coming week. However, particularly next week, as the wind turns northerly, cloud base will often lift above the summits and the air will be very clear indeed, giving superb views. Winds will also be fairly light. Not warm: some valleys will have overnight slight frost. Later next week, rain, if any, will become rare, but particularly valley temperatures will remain low at night.
