Summary for all mountain areas

Widespread gales, severe for several hours on higher terrain. Early showers from the west affect many hills, particularly Scotland where rain will be frequent; snow on high terrain. Rain slowly eases afternoon, then a warm front approaches Wales, brining more rain and rising temperatures here, spreading widely overnight.

Headline for Brecon Beacons

Gales likely; patchy rain, setting in afternoon

How windy? (On the summits)

Westerly 35-45mph. Easing for a few hours afternoon, though unlikely dropping below 30mph, then strengthening again evening into nighttime.

Effect of the wind on you?

Walking arduous in exposure most of the day with stability challenges in exposure; considerable wind chill. Effects briefly lighter in the afternoon but will deteriorate again.

How Wet?

Patchy rain and drizzle, more widespread afternoon

Rain on and off, often drizzly on the high tops where in cloud, some dry periods as well in the morning. Rain then sets in from midday, raining most of the afternoon though generally light in nature.

Cloud on the hills?

Variable low cloud, becoming extensive

Likely to cover the mountains all day from mid-elevations upward, or lower toward west and southwest. A few breaks above 700m in the morning mainly further east.

Chance of cloud free summits?

30%, lowering to 10%

Sunshine and air clarity?

Largely cloudy, hazy or increasingly murky over south and western hills. Some brighter moments and better visibility east at first, but soon becoming more widely dull.

How Cold? (at 750m)

4 or 5C from dawn, steadily lifting, reaching 8C by sundown and into night, may cool a few degrees again over the later overnight hours. Feeling like -7 to -10C directly in the wind.

Freezing Level

Above the summits.

How windy? (On the summits)

South-southwesterly 25-35mph, some gustiness. Greatest risk of strong wind west, may reach up to 40mph.

Effect of the wind on you?

Strenuous walking much of the day; some buffeting and notable wind chill. A risk of deteriorating conditions.

How Wet?

Little rain but damp/some drizzle

Some fine drizzle affects the high tops where in cloud, but rain largely isolated to westernmost mountains. With time, a risk of the rain moving further east, though likely light in nature.

Cloud on the hills?

Most extensive early in the south

From dawn, an extensive layer of cloud from lower slopes upward on southern aspects; north of high tops will see higher bases and perhaps some clear hills. Bases will lift with time, high summits likely stay in cloud, but high breaks likely too.

Chance of cloud free summits?

30%

Sunshine and air clarity?

Best chance of bright/sunny breaks on lower northern slopes where visibility will be good, though some haze.

How Cold? (at 750m)

7C from dawn, lifting to 9C. Western hills/Cambrians staying nearer 8C. Feeling just above freezing in wind.

Freezing Level

Above the summits.

Planning Outlook

West to southwesterly winds prevail during the week ahead as areas of low pressure move toward northwest Scotland; regular rainfall here, most frequent and heavy over western mountains. Weak high pressure keeps the weather drier to the south and east early in the week. Sustained gales over the mountains, only brief lulls around mid-week. Temperatures rising into mid-week with freezing levels soon lifting off summits in England and Wales for substantial snow thaws. Some thawing in Scotland too. Later in the week, becoming more widely unsettled again with cooler temperatures, at times showery with hail, some snow on Scottish Munros. The final days of February favour colder northwesterly air and a drop of freezing level; a dry and bright spell is possible early weekend.
