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.
Saturday'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.
Very warm
Warm conditions across the hills, rising above 15C on tops. Increasingly hot on lower terrain, reaching 25C+ in many valleys. Beware of dehydration.

Summary for all mountain areas
Widely windy, afternoon gales across Scotland, possibly Lakeland and Snowdonia too. In Scotland, drizzle gives way to showery rain, setting in late in the day over western hills. Patchy rain England and Wales with dry windows and warm sunny moments, but a rising risk of showery bursts through afternoon, locally heavy.
Headline for Brecon Beacons
Windy, notably west; mostly dry, later risk of heavy showers
How windy? (On the summits)
South-southwesterly 20-35mph, always strongest westernmost hills where may further strengthen for a few afternoon hours.
Effect of the wind on you?
Blustery over high terrain, buffeting gusts making walking uncomfortable in places, and walking may be more steadily strenuous over high western terrain for periods.
How Wet?
Some patchy rain, often dry
Some patchy rain drifting from the southwest from time to time, but lengthy drier windows likely too. Rising risk sudden downpours with thunder and lightning later in the day.
Cloud on the hills?
Varied, likely clear of tops for at least several hours
Patchy cloud banks, risk more extensive southwestern slopes early in day. Rising and breaking into middle of day, best east and mid Wales, and perhaps several hours of largely clear hills. In rain, banks return to higher terrain with some lower ragged patches.
Chance of cloud free summits?
Rising to 70% for several hours
Sunshine and air clarity?
Occasional sun, then a more extended sunny spell through afternoon. Some mistiness in morning. Visibility often good, but turning poor should rain occur.
How Cold? (at 750m)
14 to 16C, typically warmest east where may reach up to 18C. Still rather humid. Feeling cooler directly in wind.

Planning Outlook
Cooler on Sunday as the weather pattern returns to an Atlantic influence. Bands of rain sweep eastward early Sunday, followed by fresher, sunnier weather with some patchy showers in the north and west. This westerly Atlantic pattern dominates next week: high pressure south and low pressure north will bring alternating periods of rain punctuated by bright sunshine. Wind generally on the strong side with mild to sometimes warm temperatures, though cooler and windier spells at times produce significant wind chill on Scottish tops. Day-to-day detail currently uncertain, but western hill groups from Lakeland northward will see the most cloud and patchy rain, while east and southern areas likely drier and sunnier. This pattern is indicated to continue into the following weekend.
