The summer has just been going down hill since the end of the first week of July sunshine wise. The sunshine accumulations for Jersey, which is currently the sunniest spot in the British Isles this summer, traces its decline quite well (fig 1). And if you thought it was bad where you are, spare a thought for those in Aviemore Scotland (fig 2), they’ve only seen 211 hours of sunshine compared to the 481.9 hours in Jersey, so perhaps the cooler and cloudier conditions further north and west have now spread across the entire country.
Temperatures are not doing much better either, here as a guide are the daily CET values so far for this summer (fig 3). The heatwave in the middle of June now seems just a distant memory, and there has been a definite cooling trend in the second half of July.
