.jpg "Hazy, some fog banks"){kind=icon}
Hazy views with lack of air clarity, particularly on lower terrain, some fog banks on hills making navigation locally more difficult. If above an inversion, the air outstandingly clear.
Cool to mild
Air temperature 5 to 10C on higher terrain. Comfortable temperatures on lower terrain, but feeling chilly if exposed to wind higher up, especially if stationary. Pack extra layers.

Summary for all mountain areas
Inversion conditions still probable over Scottish Highland summits; exposed rock in fog below the inversion may be slippery, notably early. High Lakeland and Snowdonia summits near or above cloud as well. A mix of cloud and sun elsewhere as morning fog lifts, some haze below cloud later. Feeling mild to warm.
Headline for Brecon Beacons
Variable cloud layers, lifting; some sun breaks west
How windy? (On the summits)
Easterly 15mph, in palces gusty 20-25mph around some higher slopes.
Effect of the wind on you?
Fairly small, but some slopes feeling noticeably gusty.
How Wet?
No rain expected
Cloud on the hills?
Varied low cloud, may persist east
Cloud banks may fairly extensively cover eastern hills, some highest tops starting near top of the cloud layer, but likely to spill up and over higher slopes. The layer will thin and rise to the middle and high slopes, best of breaks to the west.
Chance of cloud free summits?
50%
Sunshine and air clarity?
Glimpses or more frequent sun breaks in west Wales, visibility very good here. Trending haze from the east later in the day.
How Cold? (at 750m)
8 or 9C, small variation from lower slopes upward in morning.
Freezing Level
Above the summits

Comfort of walking just becoming affected in gusty wind.
How Wet?
No rain expected
Cloud on the hills?
Cloud banks lift, largely off summits
From dawn, well broken cloud at various heights, perhaps more extensive east of Brecon at first. Bases lift to or above the high tops, though always a risk of patches grazing the tops, particularly east.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Increasingly sunny as cloud increasingly breaks. Very clear air on the high tops at first, a haze increasingly prevalent.
How Cold? (at 750m)
7 or 8C, cooler in the valleys at dawn.

Planning Outlook
High pressure lingers over the country through the later days of this week: in the mornings, varied low cloud and valley fog is likely with highest tops still possibly above the cloud layer. As the weekend approaches, the inversion starts to weaken as pressure begins to fall gradually; cloud will begin to lift to higher slopes, starting to shroud mountain peaks more often. Local cloud breaks, best of breaks in west Wales, though a haze will linger on low slopes while high pressure remains in charge. Light winds overall, an easterly breeze likely for Wales. Next weekend looks to be transitional as low pressure becomes favored. Winds rising with increasing cloud and a risk of rain.
