We haven't made it over 30 according to our two weather stations at work. Saying that though, they're both right by the river, so will always be cooler than a temp recorded inland. I know the car was reading 34 in town as we were driving through yesterday, yet when we got home, it was back down to 28, which both cars agreed on, so I assume it's pretty accurate.
We upload our info from work to the CWOP, along with a few other people in the UK - quite an interesting read if you like looking at localised weather stuff.....
Not sure why, but we haven't given them any info for 20hrs now - will take a look when I get back to work on Monday.
