Headline for West Highlands

Strengthening winds, gales; showery rain and cloud on tops.

How windy? (On the Munros)

Southwesterly 30 to 50mph, varying speeds - moderating a little in morning, then sustained speeds tending to rise again into afternoon; typically strongest from Ben Nevis group out to Mull, later gusts 60mph higher mountains.

Effect of the wind on you?

Strenuous-to-arduous walking conditions, buffeting gusts knocking you off balance on exposed terrain, increasingly difficult later on higher terrain; considerable wind chill.

How Wet?

Rain on and off

Showery rain most common toward coastal mountains, sometimes may give steadier rain locally - more often wet later in the day. Mostly light occasional rain for areas well inland and in south, fading at times during middle of day.

Cloud on the hills?

Often capping higher tops

Frequently covering hills above 800m toward coast & sea lochs, at times lower patches. Mostly above 900-1000m inland, but often covering higher slopes, and more broadly over high terrain later as rain develops further.

Chance of cloud free Munros?

30%

Sunshine and air clarity?

Glimpses of sun mostly well inland; more generally cloudy afternoon. Visibility very good where dry and out of cloud, hazier near coasts, reduced in rain.

How Cold? (at 900m)

6 or 7C, rising to 8C afternoon, little change into night. Feeling like -5 to -8C in the wind.

Planning Outlook

A changeable prospect during the week ahead. Sunday sees extensive rain moving in from the west with heavy bursts, accompanied by powerful southerly winds. Improving for many places into Monday as higher pressure expands in from the south, but showers and brisk winds continue toward northwest Scotland. Strong southeasterly winds by Tuesday, widely gales on mountains with turbulent downslope gusts toward the west; a risk of rain developing from the south during the day, becoming heavy later. Blustery south-southwesterlies into Wednesday and Thursday, showery in the west. Higher pressure tends to expand further north again into early October. Mostly mild temperatures.
