Eryri / Snowdonia National Park
Includes all summits in the the northern half of Wales from Pumlumon northwards.
Today's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy cloud and winter sun
Mostly dry with a mix of cloud and sun, patchy cloud occasionally covering some mountain slopes.
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.
Winter kit required on higher terrain
Snow cover over higher mountains. Safe progress over some terrain will require suitable footwear - possibly crampons and ice-axe where necessary.

How windy? (On the summits)
South to southeasterly 20 to 30mph, may ease during daytime, but then risk increasing again after dark.
Effect of the wind on you?
Some blustery areas, for a time affecting ease of walking and balance, considerable wind chill; may improve to be fairly small.

Risk a little rain, often dry
Patchy rain, some snow on higher tops above 800-900m, amounts small. Several hours at least may remain dry.
Cloud on the hills?
Low cloud east, clearer west
Low cloud most likely across hills from Berwyn to Bala groups, higher bases and more broken westwards, may be largely clear some hills toward west coast.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Cloudy and dull or murky eastern hills, but much better westwards, some sun best toward coast and Anglesey.
How Cold? (at 900m)
1C. Wind chill feeling like -7C early in day.
Freezing Level
1000m or just above.
Planning Outlook
Slow-moving weather patterns and a broadly similar regime to recent times over the next week or so. Scottish mountains 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, much less northwestward. Hills in England and Wales will see varying freezing levels, sub-zero for periods to 600m or lower, but intermittently lifting just above the tops - a mix of rain and upland snowfall. 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.
