Brecon Beacons
Includes all higher summits in the southern half of Wales: the Bannau Brycheiniog / Brecon Beacons National Park, southern Cambrian Mountains and highest Preseli hills.
Wednesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Frequent or persistent rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Chilly
Air temperature typically 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Headline for Brecon Beacons
Extensive cloud and often raining; very windy
How windy? (On the summits)
Westerly, shifting southwesterly, 35-45mph, easing later afternoon into evening.
Effect of the wind on you?
Strenuous-to-arduous walking most of the day with a considerable wind chill - highest speeds in exposure require more effort to maintain stability.
How Wet?
Showery rain
Periods of rain coming and going throughout the day, some extended periods are possible. Late in the day, rain may tend to break slightly.
Cloud on the hills?
Extensive, lowest west
Most hills persistently cloud covered above 500 to 700m; perhaps breaks toward high terrain east Wales.
Chance of cloud free summits?
Less than 10%
Sunshine and air clarity?
Little or perhaps no sun. Extensively cloudy often poor visibility due to fog, rain, and coastal haze.
How Cold? (at 750m)
4 or 5C. Feeling like -5C to possibly nearer -7C in the wind.
Freezing Level

Cloud on the hills?
Extensive, may begin to improve later
Cloud shrouds most mountains from 500m up well into the day. Fog may begin to lift and break late in the day.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Overcast most of the day. Very poor visibility due to fog and snow/rain.

Planning Outlook
Becoming colder for all areas during the transition into the weekend, with much mountain terrain frozen again to increasingly lower elevations - soonest toward the north and east of Scotland. A widespread frost is likely early on Saturday. Northeasterly wind will be dominant - the distribution of snow showers shifting with time from eastern hills to more north-facing mountains, particularly Scotland. Away from showers later in the week, brighter than recently with sunshine and clearer hills, most likely later Friday and Saturday. Unsettled weather returns on Sunday, with a more active week likely to follow, dominated by west-to-northwesterly winds - most precipitation in the west with some freeze-thaw cycles in central and southern areas.
