Might need to start using an indoor paddling pool to dip my feet into to keep cool if it ever gets that high. Official temp where I live is barely ever over 30 but I am pretty sure it's a lot hotter on the ground. My heat pump was reading 39 today in the sun, almost free hot water I suppose.

Also wondering about DIY cooling options. Underground is pretty chill right now. Went into a bunker and it was lovely and cool inside. Might be worth digging a nice big hole in the garden?
