Summary for all mountain areas

Weakening fronts drifting slowly southwards produce fairly cloudy skies for most places, shrouding many western hills, plus areas of rain or drizzle which may linger for several hours locally. North-east Scotland should be largely dry with highest cloud breaks. Blustery some hills.

Headline for The Northwest Highlands

Occasional drizzly rain; very low cloud west, lifting inland.

How windy? (On the Munros)

Southwesterly, 15 to 25mph, strongest coastal hills, at times 30mph in morning.

Effect of wind on you?

May impede comfortable walking at times across exposed slopes.

How Wet? (Precipitation and its impact)

Patchy rain or drizzle, mostly west in morning

Rain and drizzle on and off much of the day, most persistent western hills in morning. Tending to ease from the north, with many inland areas becoming largely dry, but leaving a few drizzly showers in west.

Cloud on the hills?

Extensive, some breaks in the east

Most hills shrouded in fog throughout the day; from lower slopes up across western hills, particularly morning. However, cloud bases more elevated and broken across Easter Ross with some breaks to tops possible here now and again.

Chance of cloud free Munros?

10% west; 30% inland and east.

Sunshine?
Air clarity (below cloud)

A few glimpses of sun across eastern hills. Otherwise, overcast. Visibility poor at first, but becoming mostly good by afternoon, especially inland.

How Cold? (at 900m)

8 to 10C, coolest near west coast.

Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Tuesday 24th July 2018

A generally humid south to southwesterly airflow will dominate the week ahead, although Scotland will be fairly fresh early in the week. Remnants of fronts bring areas of low cloud and rain or drizzle, but there will be a good deal of dry weather during midweek. Later in the week, bursts of rain may develop sporadically, with possible thunderstorms as a warm and humid air-mass extends north into Scotland. Low pressure to the west of Britain may intensify to bring strengthening southerly winds late this week, but confidence of detail low. A warm and thundery pattern is likely to continue toward the change of month.
