Fell Top Conditions on Saturday 20 December

Readings from Helvellyn summit at 12:30

Temperature plus 0.1°C Maximum wind speed 39.2mph Wind chill minus 9.4°C Average wind speed WNW 30.2mph

The slow thaw continues - it was zero degrees on the summit. There is now little snow on paths below 850m and what does remain is avoidable. Above 850m snow coverage depends on aspect with little, if any, on slopes subject to strong westerly winds. Conversely in sheltered hollows and on east facing slopes there are drifts of mainly soft snow up to 60cm although such depth is the exception. The summit plateau was covered in verglas (thin ice) making walking demanding in the strong winds.

Full winter clothing and footwear are essential for those venturing out onto the fells. For those going above the snowline and attempting, or traversing, steep east facing slopes an ice axe is recommended; for some routes it is essential. For example the exit to Striding Edge retains a steep patch of unavoidable snow; should this snow freeze then crampons would also be useful.

Met Office forecast for Sunday
