The forecast for last night was for some snow on the fells, and people yesterday (16th April) were reporting snow on Esk Pike and Bowfell, on Helvellyn, and on The Dodds, so the assessor decided to have a look at Helvellyn today to see if an ascent and re-awakening of the Lake District Weatherline service would be necessary for what remains of the winter.
From a low-level vantage point this morning he could clearly see that Helvellyn had not gathered any more snow overnight, and that what fell yesterday had melted, although there was some frosty ground on the headwall below the OS trig pillar.
Walkers should remember that despite the warmth in the valleys, lambs in the fields, and spring flowers blooming everywhere, it can still be very wintry on the tops. Wind chill is also a factor to bear in mind, and temperatures on the fells right now certainly feel well below zero - the assessor recorded -7C with wind chill on St Sunday Crag a couple of days ago.
Full waterproofs are always necessary, regardless of the season, and warmth layers are also essential. Throughout this winter season the Assessor team have had to remind people over and over again that a map and compass are absolutely essential for hillwalking. A GPS can certainly be useful, but it can also be very inaccurate, and actually dangerous if used incorrectly.
The Fell Top Assessor team of Graham and Jon would like to wish you all a fabulous and safe hillwalking season, until they return at the beginning of December for the next winter season.
