Ground conditions

Latest: 24/02/2017 19:12 Fell top Assessor's report Friday 24 February, Helvellyn summit at 14:15. Fresh snow has fallen and settled above 400m. Between 400m and 600m there is just a skittering of snow, which was thawing during the afternoon. Above 600m the snow depth rises with height although, as the snow was deposited on predominantly gale force westerly winds, the actual depth varies considerably from virtually nothing on windswept areas - such as parts of the summit plateau - to deep drifts of 70cm mainly on east facing aspects - however such depth is definitely the exception with an extremely rough average of 3cm at 900m. The snowpack is soft and, especially below 700m, wet and thawing. Above 900m, and especially on the summit plateau where the ground has been scoured of snow, were patches of ice. This could be especially treacherous on Saturday given the forecasted strength of the wind. Earlier in the day, there were isolated icy patches on paths down to 400m. Currently the forecast is for milder (and wilder!) conditions on Saturday. It would, however, only take a slight drop in temperature for the predicted rain to fall as snow and for the snowpack to harden so walkers out on Saturday should be prepared to encounter ice at altitude - along with gale/storm force winds. Striding and Swirral Edges consisted of a mixture of bare rock, wet rock and soft snow covered rock. Conversely their exits, especially on Striding, had patches of deep unavoidable snow. Again, this snow was soft but an ice axe is essential to prevent a fall and crampons should be carried in case the snowpack hardens. This advice also applies to anyone attempting, or traversing, steep slopes at altitude - especially on east facing aspects. There is quite a contrast at the moment between the Spring-like valleys and the snow and ice at altitude where the summit temperature was below freezing and the windchill minus 10 degrees. Consequently, full winter clothing - including spare layers - footwear and equipment are essential for those venturing out onto the fells. Given the forecast for Saturday it will probably be difficult to forget your waterproofs!!! Temperature: Minus 1.8 C, Maximum wind speed 21.4 mph, Wind chill: minus 10.1 C, Average wind speed: 17.9 mph.

Sun 26 Feb 2017

Some early brightness possible, but cloud soon thickening with outbreaks of rain developing by mid-morning, this becoming heavy and persistent at times in the afternoon with extensive hill fog. Some snow possible for a time over the summits. Winds will also strengthen from the southwest, becoming gale or severe gale force over the tops. Clearer conditions with a scattering of showers in the evening, the showers turning wintry.


Moderate, occasionally poor in rain. Mostly good or very good early and late in the day.

Hill Fog

Extensive around 600m during daylight hours, lowering to 300m at times.

Max wind above 500m

South or Southwest 40 to 50mph gusts 60 to 70mph around the middle of the day.


Plus 4 to plus 8 Celsius
Zero Celsius rising to Plus 3 Celsius during daylight hours, falling Minus 1 in the evening.
Freezing level:
Above the summits during daylight hours falling to around 600m in the evening.

Mon 27 Feb 2017

Bright, sunny or clear spells and wintry showers, snow mainly above 300m. The showers could be heavy at times with a risk of hail and thunder. Fresh to strong southwesterly winds at height, easing later in the day. The freezing level around 500m.

Tue 28 Feb 2017

Wintry showers or occasional longer spells or rain, sleet and snow. Mainly snow above 300m. Fresh to strong southwest becoming northwest winds at height. Freezing level around 500m during daylight hours.

Wed 01 Mar 2017

Dry and bright for much of the day. A scattering of wintry showers possible at first, then more persistent rain, sleet and snow later. Winds moderate to fresh from the southwest, strengthening later. Freezing level around 600m during daylight hours.
