How windy? (On the summits)
East to northeasterly 20 to 25mph, gusty in places around higher tops, local 30mph and tending to rise a little during day.
Effect of the wind on you?
Feeling noticeably breezy and chilly on high terrain. Ease of walking more affected locally in gusty areas.
How Wet?
Rain not expected
Cloud on the hills?
Little if any
Patches sometimes grazing higher slopes, but most cloud often above hills.
Chance of cloud free summits?
80%
Sunshine and air clarity?
Patchwork of sun, best in west. Visibility very good, some haze lower down.
How Cold? (at 750m)
3 to 5C. Feeling nearer -5C directly in wind.
Freezing Level
Above the summits, but patchy frost in valleys at first, also some sheltered higher slopes.
Planning Outlook
High pressure centred over Scotland will persist during early November bringing settled conditions. Generally dry weather, but some areas of misty dampness and regular fog on low ground, some cloud banks on hills but also inversion conditions on high tops, particularly Scotland. Overnight frost in glens will be common, plus some frost pockets for sheltered high terrain, whilst many summits will stay often just above freezing point. Light winds for several days into next week for Scotland, but stronger easterlies are likely for England and particularly Wales which would push cloud banks higher up here during the week ahead.
