By my reckoning that makes the rolling 30-day CET (June 9 to July 😎 17.2C. Not as impressive as I thought due to a run of cooler days just after mid-June (low minima).

That doesn't sound right we are averaging over 20c for the first 9 days of July 

http://hadobs.metoffice.com/hadcet/cet_info_mean.html

But the 30 day rolling mean also includes the cooler period of mid-June. Last 21 days of June come out at 16.2C average, so even a 20C+ first 9 days of July can't lift it that much. (Up to July 9 it is 17.4C now)

BTW does the http://hadobs.metoffice.com/hadcet/cet_mean_est_2018 link not get updated to the actual values? The daily figures are different on there to the final table.

Fair enongh my bad maths skills there, I have to say I don't understand that table at all, don't know if it gets corrupted when I view it but makes no sense to me. what's the -32768  mean?

It means there's no value recorded, either because the date does not exist (eg 31st June) or we haven't reached that date yet. The columns are the months and the rows are the day of the month. The values are in tenths of a degree, so 98 actually means 9.8C. I've never understood why they do it like that.

Thanks I now understand it but what a odd way to produce the data.

No the estimated table does not change. It does mean you can see how much the final numbers have been adjusted for each month compared to the provisional data. 

So quite cool in your neck of the woods then lol

July mean is 22.4c down here to date,hot hot hot

Manchester Airport and Bournemouth Hurn have a mean temperature in July of 16.6C and 17.0C respectively, so on average there is only a 0.4 degree difference between Manchester and Bournemouth - a 2 degree difference between both places so far this month would obviously indicate Bournemouth being much warmer relative to average.

You'd be best off comparing both official stations tbh.

Meanwhile, I’m stuck in the middle but would think temps here have been closer to those in Manchester. 

I don’t have a figure for Manchester but Liverpool Crosby has a mean of 19.2C which is an anomaly of 2.7C.

Bournemouth Hurn’s mean of 21.1C is an anomaly of 4.1C.

So in terms of anomalies the difference north to south is around 1.5C.

Most places in the south have an anomaly in excess of 4C.

Yeah, sorry for the sneaky post edit. 

Rostherne near Manchester Airport has a mean of 19.8C so far this month.

The way things are shaping up at the moment we are way off a 20C CET. We may struggle to reach 19C.

The provisional Hadley data has significantly overestimated the mean a couple of times in recent days, by up to 0.8C on the 7th and 1.2C on the 8th. 

My data is almost certainly understating the CET a little because I don't have access to the absolute maximums for two stations. These figures may well be much higher than any of the hourly readings.

But anyway at present I estimate the CET to be about 0.37C lower than the provisional Hadley numbers. Remember last month we had a downward adjustment of around 0.4C and we could see something similar this month.

My current estimate is that the CET will be around 18.85C by the 24th. So if we can maintain decent temperatures for the rest of the month then a CET above 19C is still very much on the cards. But the probability of beating the 19.7C record and reaching 20C looks quite slim at the moment.

Still time for that to change though. But at this point I am quite happy with my 18.8C prediction.

We could still be in the running for dry summer record but this week and next week’s convective rainfall is a threat to this. Not sure where we are on sunshine summer to date - quite good I think but not right at the top.

The one to beat I think is 1989’s combined sun, drought and warmth for the extended May-Sept season. We are in the lead on this so far.

CET running at 20.0 currently with a warm / very warm outlook. Also, looks like a more humid feel with warm nights. I’d say there’s a very good chance to challenge it.

i don’t understand why an estimate is needed. Surely it’s a case of getting the temperature values and working out an average?
