I'm not sure if this is a daft question or not - but what is a realistic measure of summer warmth?
there are the usual ones of:

1.) the mean temp'
2.) number of days to attain 20c or 21.1c and 25c

and there maybe others, but No.1 has the problem of it may be a high mean min' (not the max') that drives up the mean for the season and
No.2 could have every day in June attain 20c and then we never see another.
I average 23.4 days to attain 20c in summer (and the total No. for a full year has ranged from 21 (2015) to 47 (2013)

and we all know that a summer tends to be '3 fine days and a thunderstorm' - So I was wondering if a decent measure, at least of a poor summer, could be the number of days inbetween 20c (21.1c) being recorded.

I'm currently sitting at 17 days without a 20c and in my short past I have had 26 days a few times, but the longest is 4th August to 31st August 2011 (28 days), which went on to be 37 days with a 20c popping up on the 10th Sept'.

But then just 3 months is short, should you have a longer summer, eg: May-Sept or should you go from the first occasion in a year when 20c is recorded, but bearing in mind there are some May's when 20c isn't attained, then those gaps could be quite long?

anyway, at present I am totalling 11 days to have hit 20c this summer (17 for the year) - which at present is very low

I look at the days it reaches 21c or the old 70f as a measure of warmth

Precious few days this month - in fact non so far

I could perhaps go back over the years and count the number of days over 21c to come back with a summer warmth figure ? perhaps then compare with monthly average mean.

You could ask what is the measure (good or bad) of any season and I guess that winter and summer will be the ones that most would look at - but what does make a good/bad summer?

You could obviously look at the mean max', but what if only one month (June) was very high and the other two just below average?
If July and Aug' were then poor, you've probably not had a good summer, certainly the majority would think not because June is not the time when most will be on holiday.

Is dry, sunny, but cooler than average Ok? Possibly unlikely, but then we have just had a fairly rare dry, but mild winter.

Is two weeks of good weather OK even if the rest is mixed, especially if those two weeks are the end of July and start of August?

the cry of "It's meant to be summer" is often heard when it is raining, especially at a weekend - but what is a good summer?
Not your own ideal summer though.

My thoughts about the time period between 20c (21.1c) was just to give an indication of warmth spread out over the summer and in a way would you discount a solitary 20c and it would have to be a minimum of two together to count?

25th July to 21st Aug' 2017 equalled the total of 28 days without a 20c and I only had x1 20c in August.

Maybe the fact of just 12 days in summer notching up 20c as well this year is another sign of a poor summer.

Maybe that it was also wetter than average

Because (I suspect) overall the figures will show that it was only a little colder and wetter than average - nothing too much out the ordinary - but the reality was completely different.

True just -0.2c below average, so you could say hardly worth bothering about ???

Sunshine figure stands out, just 365hrs during the summer of 70%. Dullest summer recorded. hence the warmer nights keeping the temp up even though we didnt have the high max,s
