Early June heatwaves

[mushymanrob]

After a Spring without an early warm/hot spell, this current heatwave has took us a bit by surprise, as its been hotter and longer than anticipated.

Today is the 7th successive days of 25c+ being reached, indeed 4 days have topped 30c, and 3 daily temperature records have been broken including the June 13th enigma..

But how common are such spells in early June?.. i dont know where to find the data, but when was the last time we had 7 consecutive days of 25c+ or 4 of 30c+ in the first half of June?

[hillbilly]

Early June heatwaves  have been 1940,1947,1950,1970,1976,1992,1996 and 2006.The hottest spells at the start being both 1940 and 1947,the latter recoeding 5 consecutive days above 30 deg[albeit inc the last 2 days in May] with an extraordinary 34.4 deg on the 3rd June.

Most of those years you mention were nothing to write home about early in the month. 1996 wasn't anything compared to this in terms of consistently high temps. 1976 wasn't hot at all early on.

You can look locally at the temps for the 70s on Tutiempo.com. I can tell you that I can't find a spell as consistently hot as this in the first half of the month going back to 1973 (at Manchester Airport anyway).

It's hard to recall anything properly hot lasting a week or longer at all in the first half of June.

Here is the link for Manchester Airport- I'm sure you can find other stations more local to you too:

Have a look at the link I posted in reply to Mushy for Manchester Airport- gives you a good idea of how few really hot spells there have been in the first half of June.

Brilliant thanks- two very impressive spells. 31C in the first week in 1947. A long time since we've had anything to compete with this though.

According to those figures the Wikipedia all time records are wrong for Manchester for May- it has the all time record for May being 27C which is clearly too low.

Rostherne in this spell for comparison:

9th: 23.4C

10th: 29.4C

11th: 28.2C

12th: 31.3C

13th: 28.7C

14th: 26.4C

15th: 26.6C

16th: 27C (precise value not confirmed yet)

Trevor Harley writes about June 1947:

 

 It was very hot at the start, with a few thunderstorms. The temperature exceeded 30C on five successive days (starting in May), with a high of 34.4C on the 3rd in London and Lincoln (Waddington).

 

Absolutely exceptional to see a high of 34.4C as early as the 3rd of June, especially back then. Would be the equivalent of reaching 36-37C in that time nowadays probably.

Manchester's Heaton Park is supposed to have recorded 91°F on the 6th June 1933 and 90°F the previous day. 

 

[A Winter's Tale]

According to the Met office a heatwave in this part of the world is three consecutive days of 25C: 

Prior to this year at Glasgow airport the highest total of 25C+ days recorded in June was 4 (1982, 1986, 1995, 2018) and for 27C+ days 2 (1986, 1989, 1995, 2018). Overall, since 1973, there have only been 4 spells of 4 consecutive 27C+ days. 

This month has seen 5 consecutive days of 26C+ and 4 27C+ days. Not bad for mid June.

I often find I need to add about 4C to the BBC (privatised sheet) temps so that it doesn't lead me far off reality.

Yes,that is an incredible figure there is not a higher temperature until the 21st of the month that only just pips it at 34.5deg and previous to 2017 it would have been 23 days later on the 26th of the month.

I recall early June 1982 being hot and humid and this is confirmed by Philip Eden. In London, Brazell noted June 1933 as 1.3F above the mean for June, and 1947 as + 1.6, with 3rd June 1947 being the hottest day (90.9F) of a hot summer.

That was correct, late May and early June 1982 was hot, humid, hazy with local thunderstorms.

Incidentally, before this year the general rule was that if a fine spell developed late in May, it was unlikely to survive far into June. Good examples include 1982, 1985, 1997, 2003, 2012 and 2021. In all those years except 2003, June was rather poor and in the majority except 2021, the fine spell didn't last beyond around June 7th.

So when the fine spell really got going around May 20th (previous week was sunny here but there was more convective build-up inland) I fully expected it to barely last into June. To continue until June 16th was really quite impressive.

I dont think that it has been that impressive.Yes it has been a very long dry spell but it has only been since the 10th that high temperatures have arrived.We have had days of 24 to 28 deg since the 10th and it is only 22 deg today but previous to the 10th we had only 2 days above 20 deg all year with the majority of temps between 16 and 19 deg and feeling very chilly out of any sunshine.

A seemingly forgotten one, early June 2004.

31 degrees in Central London on the 08th.

Not quite early June, more mid June, but 2017 had a notable heatwave between the 14th and 21st.

I haven't forgotten it. Perfect conditions in Sheffield for viewing the transit of Venus.

Remember June 2017 being a consistently very warm month. Eclipsed by June 18 so doesn't often get mentioned. 

We have had a truly memorable spell of heat, I think we managed 7 days 25 degrees or more, yesterday didn't quite make it and today saw 23 degrees, still very warm for mid June.
