The Met Office definition would equate "uncomfortably hot" quite well

max=30°C and min=15°C

That range would be "intolerably hot" to me, was bad enough today in
Hexham, might have been in the low 20's. Very pleasant at home 15C
and a nice F4 to keep things cool. B-)

... as it's the muggy nights that I find hardest to take.

Low thermal mass house? The hefty stone walls here never let the
inside get much above 23C in the living areas even if the max outside
is pushing 30C for days. In the winter you don't let 'em cool by
switching the heating off if you are away for a day or two, as it
will take a day or two to warm back up!

1950s brick, though it does have cavity wall insulation installed in the
1970s, which might keep the inside a bit cooler in hot weather than it
would otherwise be.

Unfortunately the sun shines into my bedroom in the evenings, and even
with the curtains drawn it tends to heat up even if it hadn't been too
bad till then. In really hot weather it can get up to 26C or so, which I
find makes sleeping difficult.

When I was younger during my GCSE years I had a west facing bedroom and
it used to get really unpleasantly hot in the evenings, up to around 35C
as measured by a wall thermometer during the 1995 summer.

Hi



If you use the strict definition of a heat wave on the daily CET series as defined in the latest Met Office news blog (http://metofficenews.wordpress.com/2...s-a-heat-wave/) i.e. max=30°C and min=15°C, I can only manage to find 5 occasions when this happened in the record back to 1878:



01 1923 12 Jul 13 Jul = 2

02 1948 28 Jul 30 Jul = 3

03 1976 03 Jul 05 Jul = 3

04 1990 02 Aug 03 Aug = 2

05 1995 31 Jul 03 Aug = 4



Personally I think for the larger Central England area, making the thresholds match the old 60°F & 80°F value marks (min 15.5° & max 26.6°C) you would end up with a larger but still relatively small list:



01 1878 27 Jun 28 Jun = 2

02 1921 18 Jul 19 Jul = 2

03 1923 11 Jul 13 Jul = 3

04 1926 13 Jul 14 Jul = 2

05 1933 04 Aug 06 Aug = 3

06 1935 23 Jun 24 Jun = 2

07 1947 17 Aug 18 Aug = 2

08 1948 28 Jul 30 Jul = 3

09 1955 22 Aug 23 Aug = 2

10 1976 03 Jul 05 Jul = 3

11 1983 12 Jul 13 Jul = 2

12 1983 15 Jul 17 Jul = 3

13 1989 21 Jul 24 Jul = 4

14 1995 31 Jul 03 Aug = 4

15 2003 05 Aug 07 Aug = 3

16 2006 19 Jul 22 Jul = 4

17 2009 01 Jul 02 Jul = 2



If you lowered the thresholds even more then you would be flooded with events that might not be as memorable. I can certainly remember a lot of the events since 1976.

Very interesting and well-researched, TY. It's that minimum value which is limiting the number of "heatwave" days, I would think. If the value was simply 30C in the daytime, I would imagine we would have had many more and longer, heatwaves. Is that right?

Dawlish

I did a rejig of the code and surprisingly removing the minimum threshold made only a bit of a difference - 10 instead of 5 occasions:

Max=30.0°C minimum 2 days or more

01 1906 31 Aug 02 Sep = 3
02 1923 12 Jul 13 Jul = 2
03 1948 28 Jul 30 Jul = 3

08 1990 02 Aug 03 Aug = 2
09 1995 31 Jul 03 Aug = 4
10 2006 18 Jul 19 Jul = 2

If I lower the max threshold to the old 80°F then I catch over a 100 occasions...

I suppose it doubled the number, but I'm surprised as well! I really did expect this figure to be a lot higher.

Thanks for the efforts. Much appreciated, Bruce.

I didn't find it nearly as unpleasant as more recent hot spells. I
suspect that was partly because, being younger, I could acclimatise more
easily and partly because, IIRC, the humidity was generally low.
