Rather chilly ground temperature at -13°C outside the tent, overnight 13th to 14th July 2024, altitude around 2150m in Troutbeck.
Fortunately I was ‘double bagged’ overnight. The previous nights (mornings) I had been wondering why my sleeping bag wasn’t keeping me warm enough …alright it gets a bit frosty up here, but this is Zimbabwe, not Scotland, how cold can it be….?!
Anyway I took the extra bag (ex Isle of Man TT charity shop bonanza – thanks Mum!) and had a pretty good night’s sleep. The first clue was the frost on my shoes in the vestibule.
The sleeping bag is rated at 4 °C for comfort, -1 °C for comfort limit. Clearly I was well beyond that.
I doubt the air temperature would have been as low as -13 °C though – the ground emitting heat as radiation much more easily than air!
The 3F UL Lanshan 2 which re-froze in this shape after I slackened off the guys in preparation for the sun striking it. We eventually reached 20°C in the afternoon.
The weather ‘forecast’ was saying 6°C overnight for Troutbeck Extension!
