Having clicked the Manchester link and then somehow come back to Leysdown, I've deleted and reposted - this time with the proper figures!

Using the 6z GFS for Manchester (a crude proxy, but it works), you would end up with 13.8. There are three exceptionally high days (21.5, 20, 20.5), but then it turns much cooler with 13, 14, 12 and 12.

Bear in mind though the GFS isn't exactly covering itself in glory at the moment, and the end of the month is still very much up in the air!

I thought we didn't get adjustments anymore?

Oh, it is the hottest on record so far - in terms of globally, and in the northern hemisphere, just not the UK. No doubt when that gets reported (via the Met Office) those people will then point out that it's been "freezing cold" here, so global warming is a scam.

Incidentally using the Manchester proxy method this morning gives 13.1 up to yesterday (assuming that 12.9 wasn't 12.85, otherwise it's more likely to be 13.0), then 14.1 by the end of the month (the end of which is a few degrees warmer than yesterday's 6z run).

Interesting thought. I note that the HadCET data still says 'provisional'. Maybe it's just no longer the regular adjustment.
