None of those temperatures are "Extreme Heat" in my book. Just a couple of standard summer days. This brainwashing language just keeps going on and on. 

Extreme heat would be mid to upper 30s, not mid to upper 20s.

Its ridiculous and fits a certain narrative. Can't imagine what that narrative is!

Errm, where did I say they were "extreme heat"? I'm simply posting the temperatures I've hard around here this weekend, so I really don't know what your point is?

Tbf Bolton isnt in the amber warning zone. It is a bit random though. It looks just as hot further east, London for example.

Sorry I wasn't pointing this at you! Just saw BBC forecast and the news that Met Office now issue "Extreme Heat" warnings.

Fair enough, but not at 28-30c. That's patently ridiculous.

Agreed I bet they couldn't wait to issue that warning 😂

I consider 'extreme heat' would be 32c+ in the North and 35c+ in the South, even that isn't all that extreme. A few days of 29/30c I would expect to hit in almost every Summer.

Spot on. Just a usual summer spell. They want to brainwash people into their narrative.

Well apart from no-one saying those particular temps are "extreme heat", would you consider 5 days with a max of -5c or lower in January to be extreme cold?   Which would be the equivalent in winter.  Bearing in mind such a thing almost never happens in lowland England.

The difference being, most people can cope in this country with such cold far better than than can with a run of 30c+ days and associated very warm, humid nights and lack of sleep.

You may be a lizard.  Not all of us are.

But Bolty doesn't even live in Bolton, this really is getting a bit random!

I don't think the equivalent would be sub -5c maxes in Southern England that probably didn't even happen in 1963 that often. Would be more like a run of maxes of around 0 - 1c which to be fair would be quite noteworthy.

Though I still think the terminology of using 'extreme heat' is sensationalism, a level system would be better.

Anyway, as Moomin is not head of the Met Office (why not?!!!!) this is the original release explaining extreme heat warnings:

I will do in a few weeks.

No worries it happens.

Though yes I agree. 28-30 is hardly "extreme heat". It would generally be considered typical summer heat elsewhere. Even in the UK those temperatures aren't really that remarkable.

Even over here, such temps are not all that remarkable, but today's 28c here locally was coupled with a dewpoint hovering between 19-20c all day, which is remarkable (for here) and highly discomforting. Even during the heatwave of June 2018 where temps reached higher values, dew points themselves were far more favourable.

Heathrow reached 31.4C today so slightly lower than yesterday.

Southampton Oceanography Centre reached 31.5C. Not sure if the Met Office include that station in their highs and lows but it is an official SYNOP station. I was in Southampton today and it was certainly very steamy.

 

 

Re "tropical nights": this is an international (well at least European) term of long standing - the French refer to nuits tropicales as anything not going below 20C. So I think that's where the terminology comes from.

They also refer to 25C as a "summer day" in their statistics, i.e. how many summer days were there this month. I like that, we should use it too although perhaps toe it down a couple of degrees to 23C to fit the UK climate.

Whilst think that the use of the word 'extreme' to justify the heat is sensationalist I do think the warning is justified. The Southwest and Wales don't have these sorts of temperatures often and people are genuinely not used to them.
Take Cardiff for instance the all time high there is 34c. This Thursday the Met office forecast is for 32/33c.
It's also forecast to get up to 30c in coastal locations widely across Wales and the South West which is really quite unusual.

It's the equivalent of the South East hitting 36/37c which would, sadly, cause many additional deaths and issues as will this heat down here.

Just for the record, here in west Cornwall approximately 1.5 miles (as the crow flys) from the sea.
We have now recorded 3 days in a row with temperatures exceeding 25c. I haven’t recorded that since since the hot July of 2006. Tomorrow down here is meant to be close to 28c, now that is fairly uncommon down here so close to the ocean on three sides. 

---

Yes the location of the heat is a big factor behind the warning, along with the fairly high humidity and slow drop off of temps after sunset.

Got to 30.3 here today which is not all that rare these days (but was pre-1990s bar a few exceptional cases), yet is also within four Celsius of the record high for any time of year. Such is the suppressed nature of hot weather in the rural west & southwest.

Agree that ‘extreme’ seems a bit much, though I think it has a lot to do with spurring health-protecting action. If it was just ‘hot weather warning’ I sense it wouldn’t be nearly as effective. Could be wrong, mind!

I get the impression it is not just about the max temperature. It is about the overnight lows and the humidity as well. 

Certainly to me the last couple of days have felt more oppressive and uncomfortable at 29-30C than last year’s 35-36C did. 

---

Yesterday here it reached 32.6c at 16:07 and today slightly less at 32.1c according to my Vantage, true reading or not I don't know, it's normally pretty spot on. Whatever it is it's not my cup of tea, roll on winter.

Aye, it's not the actual max temp that matters - it's the period of time at which temps remain significantly above normal (couple with humidity)

All this talk of 30C+ in unlikely places has got me thinking, what is the most northerly place in the UK to have recorded 30C? I'm pretty sure that it's been done in the central Highlands, possibly even the west coast of Scotland, but further north than that? If it has been my money would be on the Inverness/Moray Firth area, can't imagine it's been achieved any further north.

It's nigh on impossible to check all the station data to find the most northerly location of 30C biut much easier with the Met Office / CEDA gridded data by date and location

Using the broader 5km timeseries data from 1960-2019 2 dates appear quite frequently as possible candidates. These are 9th August 2003 and 1st Jul 1976 which both show temperatures over 30C in the far north. Of these 9th August 2003 is the hotter and more prevalent asnd is used here.

The 1km gridded data for this area is below. It is based on station data so far as I am aware but then extrapoltated and interpolated to fill in all the 1km cells - this means it cannot be regarded as an "official" reading. However some of the cells recorded over 31C so I am pretty convinced 30C was exceeded in this area on that day.

The map below shows the geographic details and nearby locations
