From the BBC:
Heatwave alerts for much of England http://www.bbc.co.uk/news/uk-23283198
They forecast for Xi'an (whereas I currently am and will be for the next couple of days) is 30 degC and a humidity level I've not experienced since Singapore. It's like this all way to Beijing (2 weeks) and then I'm back to desert heat for some of Mongolia.
The ~40degC heat we were doing a couple or weeks ago seems like a lifetime ago.
I'm sure I'll complain about the weather when I get back (I'm British, it's what we do), but I hope I'll complain a lot less about it.
