Sunshine of late seems to have been endless with the past 10 days being virtually cloudless from dawn to dusk.
After a very sunny March which saw over 170% of average sunshine recorded at Heathrow April has already seen over 56% of average sun hours in the first eight days.
In terms of the total percentage possible of sun hours the past 11 days are second only to a period in 1990 that stretched from April 27th until May 7th.
In March I attended an avalanche course to try to better understand the dynamics of what causes masses of snow to suddenly roll down a mountain.
The Swiss Mountain Training level 2 syllabus didn’t disappoint and over the course of three days I was soon digging snow pits to study the layers and what causes them to occasionally release.
Shovels in hand I, along with my fellow students, was soon digging down to a depth of over 150cm. Probes revealed a huge temperature difference; from -11C at the surface to just above freezing at the base.
