How windy? (On the summits)
Westerly 15 to 25mph.

Starting to affect comfortable walking on exposed high tops and ridges. Noticeable wind chill.

Banks of cloud over higher slopes early in day, bases tending to rise and break above many tops middle of day and often clear afternoon. Some patches may return into evening western Cambrians.
Chance of cloud free summits?
80%

Fairly cloudy start, then sun breaking through, increasingly sunny afternoon. Visibility reduced in early showers, then good becoming very good.

Planning Outlook
A complex pattern into the start of August as weak low pressure is nearby to the west. Some showery bursts of rain, possibly thundery in places on some days, locally persistent rain possible, but some places may well escape drier. Cloud varying over the hills from day to day. Strong southwesterly winds later this week, then becoming more variable in speed and direction over the weekend into early next week, may strengthen again for periods. A generally showery westerly may then prevail during next week. Temperatures near average or on the cooler side for Scotland, warmer for Wales and Peak District. Beware ongoing fire management restrictions to access despite rain in the forecast.
