Wow that's awful. Why was it so bad? Just unlucky with cloud cover?Eh multiple factors I guess. Mostly the gulf stream. On the bright side, there's always next summer!
Meanwhile I can't remember a sunnier or hotter June in the UK. I've been absolutely boiled, high 20s/ low 30s every day for a few weeks is not something I'm used to. Still, not hot enough or long enough to warrant any AC. Maybe should have bought myself a fan though
And yeah that's what makes it especially bad. Even Denmark has been having a crazy summer
