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.
Thursday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
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
Freezing temperatures in Scotland and England; freezing level lowering with time to middle slopes, first in eastern hill groups. Blustery as well, gale force gusts on high terrain of Scotland and Wales. Snow flurries affecting eastern Scotland and the Pennines, mostly dry Lakeland to west Scottish Highlands.
Headline for Brecon Beacons
Windy, gale force gusts; some rain south, more late in the day
How windy? (On the summits)
Southeasterly 30 to 45mph, some variability in speed and gusty around higher exposed summits and locally downslope toward west Wales. Most powerful gusts may reach up to 50mph+.
Effect of the wind on you?
Walking at least strenuous all day, to locally challenging in strong gusty wind - prepare for changes in conditions. Significant wind chill.
How Wet?
Afternoon rain
Some patchy rain drifts onto southern slopes through morning, many hills will stay dry. Increasing risk of rain with time in the afternoon, most extensive in the east, falling as sleet on the tops, raining more widely for several hours after dark.
Cloud on the hills?
Extensive
Shrouding most hills all dry, to mid elevations or lower on south and east slopes. Some higher bases westernmost areas, particularly around the Cambrians, though unlikely breaking above 600m.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Largely cloudy, hazy and dull, poor visibility across the hills.
How Cold? (at 750m)
1C, lifting to 2C on most hills. Wind chill feeling like -10 to -13C.
Freezing Level
Variable, mostly above the summits, particularly later, but lower early in the east, to 700-800m for a time.

How windy? (On the summits)
South or southeasterly, speed likely vary during day, typically 15 to 25mph; strengthening later, 35-40mph into dusk.
Effect of the wind on you?
Mostly fairly small effect on walking, but prepare for noticeable chill over exposed higher areas, then increasing effects later.
How Wet?
Risk rain developing from south
A little patchy rain, though several hours may be often dry early/around midday. Rain moving in from south with time, becoming frequent-to-persistent by day's end.
Cloud on the hills?
Fairly extensive, lowest east
Areas of low cloud to some mid-slopes in eastern areas, more broken cloud west. May vary, rising in places, but covering most higher slopes where rain develops, increasingly widespread later.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Cloudy and dull or murky on eastern hills, better westwards, glimpses of sun. Becoming more widely poor if rain sets in.
How Cold? (at 750m)
2 or 3C. Wind chill feeling like -5C.
Freezing Level
Above the summits.

How windy? (On the summits)
Generally southwesterly 15-25mph, may be stronger for periods in exposure.
Effect of the wind on you?
Often fairly small, but blustery in exposure, walking at times becoming strenuous.
How Wet?
Intermittent rain
Periods of rain will come and go through the day, perhaps heaviest and most persistent early in the day. Rain from prior days making wet conditions underfoot.
Cloud on the hills?
Soon lifting to mostly affect high terrain
Widely extensive to middle slopes at and before dawn, soon lifting and breaking to mostly just affecting the high slopes, breaks off some tops are probable. Cloud will fill in for periods as rain comes.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Cloudy early, glimpses of sun soon breaking out, increasingly extended. Often good visibility out of precipitation.
How Cold? (at 750m)
2 or 3C, rising a degree later.
Freezing Level
Above the summits
Planning Outlook
Slow-moving weather patterns and a broadly similar regime to recent times over the next week or so: periods of precipitation will affect most mountains at least every few days. Scottish Munros generally below freezing point, with snow cover and drifts most substantial from the Cairngorms to central and southern Highlands, some additional falls in the week ahead (with continued flooding risk too); much less northwestward. Hills in England and Wales will see varying freezing levels, at times dropping sub-zero to middle slopes, but largely isolated to the high terrain of Lakeland and Eryri NP (Snowdonia). Wind speed will vary, some periods of lower speeds than recently, though gusty SE'ly winds remain common in the Highlands. Scope for widely colder conditions toward mid February.
