Whoah, my conservatory reached 39 degrees!

NOTE: I'm in England.
Hi all, after returning home from helping a mate decorate his dads house house that he's just inherited I went into the conservatory (my pcs in here) and was litterally hit by a heatwave, cutting of any chances at breathing normally it was that hot.

We decided to place a thermometer in to see how hot it was and my bro said it reached a whopping 39'C! (thats about 90 f isnt it?).

Glad I took my sleeping cat out of here before I set off.

Edit: Sorry it was 39 not 49.
