Headline for West Highlands

Patchy rain and blustery; higher cloud bases inland

How windy? (On the Munros)

Southwesterly 25 to 35mph, speeds likely fluctuate during the day, some stronger gusts over high tops to 40mph. Lighter speeds far south late in the day but then deteriorating into night.

Effect of the wind on you?

Affecting comfortable walking, at times more strenuous on exposed terrain and balance may be challenging on ridges; notable wind chill.

How Wet?

Patchy light rain and drizzle

Often drizzly over high tops, patchy rain drifting from the west, generally light in nature with only odd spots pushing well-inland. Rock surfaces slippery even if only small amounts of rain.

Cloud on the hills?

Fairly extensive, lowest coasts

Covering many hills much of the day, lowest bases over coastal areas and islands, sometimes to 400-600m. Rising well-inland towards 800-900m, occasional breaks above this height. Beginning to fill in extensively as evening turns to night.

Chance of cloud free Munros?

10%, to 30% well inland

Sunshine and air clarity?

Brief glimpses of sun inland glens, though weakened by high cloud. Some haze below cloud near coast, better visibility inland where out of cloud.

How Cold? (at 900m)

6 or 7C at dawn, rising inland to 9C; only slight rise along the coast. Feeling like 0 to -5C directly in the wind.

10%

Planning Outlook

Westerlies prevail across northern Britain. Rain, drizzle and low cloud over western hills from Lake District northward through the weekend. Temperatures near average, but feeling cool in exposure to wind on tops, which could regularly be quite strong and gusty. Generally drier northeast areas with higher cloud bases but patchy rain and drizzle reach here too. Higher pressure south maintains drier conditions in Wales and the south Pennines but cloud and some drizzle will affect high western slopes from time to time. A drier and warmer window looks probable from middle next week as high pressure builds. Very warm temperatures for England and Wales, spells of sunshine more widely. Some showers and patchy rain are likely to continue through late week and next weekend, though detail is uncertain.
