How windy? (On the Munros)

Direction varied; 10mph or less.

Effect of the wind on you?

Negligible

How Wet?

Rain not expected

Cloud on the hills?

Most summits cloud free by late morning

Ribbons of fog from valleys up after dawn, perhaps extensive N & E Cairngorms NP. Nevertheless, some summits cloud free (in places above the fog). The cloud will clear, although may leave patches below about 900m N Cairngorms and Deeside.

Chance of cloud free Munros?

70%

Sunshine and air clarity?

Banks of cloud will tend to break up to give sunshine (in places perhaps above lower cloud). Haze may persist in some areas, but particularly higher up visibility excellent or superb.

How Cold? (at 900m)

10C at first and in cloud, rising as high as 17C by afternoon.

Freezing Level

Above the summits.

Planning Outlook

Remaining warm and particularly England and Wales humid. However, thundery rain will become mostly confined to Wales, whilst the Scottish Highlands are extensively dry. Overall extensive sunshine, although banks of very low cloud, mainly more eastern mountains, including those in east Wales. A change to wetter and gradually less warm conditions across Britain is likely early next week.
