Summary for all mountain areas
Blustery start, gale-force gusts in N England and Scotland; easing. Chilly with showers in W Scotland, showers more widely over the highlands afternoon with sunny interludes. Early showers in England and Wales ease by afternoon, only well-scattered showers remain over Wales and S Pennines, plenty sun breaks.
Headline for Brecon Beacons
Breezy early, easing; risk of showers rising through afternoon
How windy? (On the summits)
Westerly 25-30mph at dawn, strongest east, soon easing and shifting southwesterly to around 15mph, and may well be lower for several midday hours. Shifting southerly later afternoon and beginning to restrengthen, 30mph high west tops by evening.
Effect of the wind on you?
Mostly small effects most of the day, though ease of walking impacted on the high tops in the earliest and latest hours.
How Wet?
Scattered showers developing
Only odd patchy rain in the early hours, most hills dry, then an increasing risk of showers developing from noon. Dry windows still likely, but some risk of a cluster of more showers passing north from the Bristol Channel later in the day.
Cloud on the hills?
Summits become substantially clear
Patchy cloud from 500-600m in the morning, some risk more extensive just at dawn, but a lifting and breaking trend with time, summits likely clear by afternoon. Some odd caps may return to tops later in the day during showers.
Chance of cloud free summits?
Rising to 90%
Sunshine and air clarity?
A patchwork of sunshine, high cloud thickens through afternoon. Good visibility, some light haze around.
How Cold? (at 750m)
5 or 6C at dawn rising to 8C or a degree milder further east. Only small drop into nighttime. Feeling like -3C strongest early wind.
Freezing Level
Above the summits.

How windy? (On the summits)
S-SE'ly, then SW'ly, high uncertainty of extent of stronger winds - likely in range 35 to 50mph; lighter for a few hours.
Effect of the wind on you?
Beware of changing conditions - risk arduous or difficult at times, but also a period of lesser effects.
How Wet?
Risk periods of heavy rain
Persistent rain setting in just before dawn and lingering for several hours after sunrise, likely some heavy moments. Trending patchy, increasing chance of breaks later, but southern slopes stay wet longest.
Cloud on the hills?
Extensive
Shrouding many hills much of the day, from low-mid slopes upward southern areas, highest bases toward eastern mid-Wales. Some brief moments of improvement possible, and perhaps a greater chance late in the day.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Overcast, mostly dull, poor visibility in rain, locally better if dry northern areas for a time; may start to improve later.
How Cold? (at 750m)
6C rising to 9 or 10C afternoon, notably lowering into evening-night. Feeling below freezing in the wind.
Freezing Level
Above the summits.

How windy? (On the summits)
Southwesterly 25-35mph, gusty over tops, particularly early in the day.
Effect of the wind on you?
Ease of walking always affected, including to low slopes, more strenuous over tops where feeling chilly.
How Wet?
Little rain expected
A few spots of light rain here and there drifting from the southwest, perhaps a fine drizzle on the summits in the early hours, but most hills substantially dry.
Cloud on the hills?
May cling to high terrain
Fairly extensive cloud above 600m in the morning, lowest bases to the southwest as low as 400m. Lifting with time, perhaps clearing most or all terrain, but a risk of caps clinging to the high summits.
Chance of cloud free summits?
Rising to 60%
Sunshine and air clarity?
Weak sunshine through high cloud, trending patchier through afternoon. Good visibility, though some haze west.
How Cold? (at 750m)
8C rising to 10C, or 11C east hills. Feeling near freezing in strongest wind.
Freezing Level
Above the summits.
Planning Outlook
Unsettled over the weekend as southwesterly flow draws several areas of rain across the country, best of dry slopes to the northeast, and perhaps a drier Sunday for England and Wales through blustery, some uncertainty in detail. Generally unsettled next week too: showers affect most hills Monday and Tuesday, lowest cloud and most persistent rain along western slopes, but with some breaks as well with sunshine. Timing of most unsettled weather remains uncertain, but some risk of a deeper area of lower pressure from Wednesday or later brining widespread strong winds, probably gales over many summits, with prolonged heavy rain. Temperatures probably trending milder again into the weekend, pressure may begin to rise in the south, but this uncertain as well.
