Going by the 12z GFS it looks like peaking close to 18.7C on the 4th, then dropping somewhere in the mid to high 17s by the 10th.

I am afraid the most severe punishment of all - it won't count!

In the EWP, have created a spot in the scoring where these too-late forecasts get a score so at least you can track where your forecast ends up scoring potentially against the field. It is not part of the official scoring for the contest but when I post August results in early September, look underneath the alternate "ultimate scoring" section which tracks scores against later-adjusted Hadley table entries. Missing a month in CET is less punitive as your average errors count for large fractions of the score.

If it finished on this value it would make it the 3rd warmest August on record - the weather has seemed just so so up to now !!

Has it? It's felt very warm and humid to me- no outstanding maxima but it's been noticeably warm overnight and consistently between 22 and 24C by day. If that continued it would indeed deliver a very high CET.

Agree, although the CET will take a hit towards mid month, will almost certainly finish above average though.

On average I believe the first week of August returns the warmest CET mean of the year. The start of the month has been warm largely due to high minima which is very easy to attain under cloudy skies at this time of year. The air has had a tropical maritime source to it, very high minima and slightly above average maxima - no heatwave by any means but warm.

The outlook shows more of a polar maritime influence at times, which will inject some cooler uppers and see minima return to average coupled with average and at times below average maxima, however, if we maintain a predominantly atlantic influence this month, we could see quite a decent CET but no real warmth - a CET that will disguise this, thanks to high minima and cloudy grey wet skies. I am not a fan of August, high minima does nothing for me, unless accompanied by warm/very warm dry sunny skies..

Checking the Hadley website. Mean minima is 2.5C above and maxima is 3.0C above.

Doesn't really back up what you have said here at all.

Also minima tends to get corrected downwards more than maxima.

Looks like a fairly average fortnight temperature wise coming up but probably finishing comfortably above average thanks to the warm start and possible warmer interludes further down the line.
