How windy? (On the summits)

Southwesterly 10-15mph at dawn, shifting southerly and gradually strengthening, 35-45mph by dusk, strongest west.

Effect of the wind on you?

Fairly small early, walking increasingly impeded for arduous conditions and significant wind chill by dusk.

Substantially dry

A few spots of drizzly rain occasionally drifting into the mountains from the southwest, may be more frequent for a few hours later morning, but the hills otherwise dry.

Cloud on the hills?

Mostly little

Variable banks of cloud in the morning, these lifting and breaking after sunrise for often clear hills. Occasional caps may graze the high tops.

Chance of cloud free summits?

70%

Sunshine and air clarity?

Largely cloudy, some weak sun through high cloud with occasional brighter moments east. Good visibility.

How Cold? (at 750m)

+1C rising to 4C, staying lifted for several overnight hours. Later, feeling like -8 to -10C in wind.

Freezing Level

Just touching the high tops at dawn, lifting above the summits.

Planning Outlook

Variable weather regimes in the extended forecast. Atlantic west-southwesterly winds will be dominant, with low pressure to the northwest of the country, brining cloud, rain, and mild temperatures, often followed by sun, showers, and cooler temperatures; rain will be increasingly common to the high Munros, but the snowfall level will lower too during periods of cooler weather, and perhaps to high Lakeland fells too, though any snow unlikely to accumulate here. In the longer term, indications of high pressure increasingly building from the southwest, brining drier, brighter, and milder conditions to England and Wales and occasionally Scotland too, though the risk of occasional rain and cooler temperatures remains.
