Dull, wet and blustery with frequent rain and extensive hill fog.

How windy? (On the Munros)

Southwesterly 25 to 35mph, perhaps 40mph for periods on higher, particularly summits toward the coast.

Effect of wind on you?

Walking arduous across the hills, and on some higher coastal areas progress difficult.

How Wet? (Precipitation and its impact)
