A huge temperature inversion here in the Otter Valley this morning. Left home about 8:30 and the car thermometer was showing just 3°C but this rose abruptly to 14°C halfway up Four Elms Hill between here and Sidmouth.
Normally the inversion boundary yields a temperature difference of 4°C or 5°C at most – not 11°C!
Also it is quite interesting to note that as you meet the inversion boundary the car’s windows suddenly mist up. I’ve got used to it now and expect it whenever there is an inversion but when I first encountered it, I was a bit shocked to suddenly lose sight of the road as all the windows (and door mirrors) mist up on the outside whilst driving up the hills on either side of the valley.
A maximum of 22.8°C and unbroken sunshine all day. Temperature held back a little by a sea breeze that started early this afternoon.
Sunshine recovering at 157 hours but still a way to go to get to the average for the month so far.
