This is the obvious answer as it's not part of the UK. I guess the same would apply to the Isle of Man. OK, never likely to hold a temperature record but could quite easily have highest wind gust or rainfall total. I imagine these would be discounted too.

I thought maybe the night after the record heat in 2019 was a record breaker , it didn't drop below 21c here but on second thoughts i am not convinced it was above 20c at 9am on the day of the record heat, thus the minimum not being broken, as the heat rapidly built during the day.  

That's a matter of definition. They're part of the legally defined "British islands" but not geographically part of the British Isles. And even if they were, I think it makes much more sense for national temperature records to be defined by political divisions. After all, the Republic of Ireland is part of the geographic British Isles but we don't try to claim their weather records.

Plus Jersey has its own Met Office.

Incidentally 31.8C wasn't the hottest temperature on the island yesterday: it was actually 33.2C at Maison St Louis: https://twitter.com/Jersey_Met/status/1546896254201888775

The met office have issued an England wide level 3 heatwave alert from 9am Saturday to 9pm Tuesday

Gonna be a short lived record. Next Monday night will be a stinker.

I’d always assumed the CI numbers were included in the UK data but I can see why they wouldn’t be.

I have just come across this report from STV (the Scottish Equivalent of ITV) News about those really high temperatures from the night before last when we came fairly close to recording a tropical night here in Edinburgh.

According to that report, Aboyne in Aberdeenshire had its warmest July night on record with an overnight minimum temperature of 18.2°C on that night. That is a location which is a lot further north than where I am here in Edinburgh, and the previous July record up there was only 16.8°C as set as recently as 2018, so that record was smashed by quite a lot.

Here in Edinburgh, I have been mentioning quite a lot that the night before last might have been our warmest night on record here in Edinburgh. It certainly was warmer here than any other night which I know of according to all of the data which I have for here.

As it turns out, that wasn't our actual warmest night on record here in Edinburgh so if anyone knows when that actually happened, what station in Edinburgh this happened at and what that highest ever minimum temperature actually was, I would be grateful if he/she could post that info here as that will help to keep my own records straight as well.

However, the night before last night was confirmed as our warmest July night on record here in Edinburgh and as expected (since that was where the highest temperature of that night was recorded), it was at the botanic gardens in Edinburgh where this record was set. According to my own data, the lowest hourly temperature reading on that night was 18.9°C.

That was all the data which I have and of course, the lowest hourly temperature reading is always going to either the same as or higher than the actual minimum temperature which is the more important statistic here.

It is therefore, the 06z raw SYNOP/BUFR data which will officially confirms that actual minimum temperature when it comes in. However, it also turns out that this wasn't actually all that much lower than the lowest hourly reading in this case.

From that raw data at 06:00 yesterday morning, the actual overnight minimum temperature at the botanic gardens in Edinburgh on the night before last night was 18.8°C and that is what in the end, confirmed that particular night as being our warmest July night on record here in Edinburgh.

EDIT

I've just realised that I didn't fully read that report properly because on further inspection, I read that the actual all time record for our highest ever minimum temperature here in Edinburgh was 18.9°C as set in August 2006, presumably at the botanic gardens again although the report doesn't actually confirm that.

This means that we weren't actually all that far away from getting our warmest night on record the other night there and if we get a hot August this year, that record could well be beaten then.

That's what I said. 

What who said? 😂😂

Tuesday night probably too in eastern areas.

Add my local weather station, Farnborough, to the list of stations that have gone offline. No readings since 0900Z yesterday.

Our reporting network is not fit for purpose. When will the MetOffice start investing in this properly?

Could be a day for Gosport Fleetlands.

Can we squeeze another 30c day. Going to be tight.

I think that list is very out of date as it still has Gravesend on there

The link I posted in the other thread about the 2019 heatwave has a map showing the various stations that were reporting then, but they are not named. As well as the ones we see hourly data for there are others that never seem to come up. It also mentions, eg a Sheffield weather station which I didn't even know existed.

There's a big gap in the network across the Fens to the north of Cambridge. I wonder if a suitably placed station there could have broken 39C in that event?

Meanwhile in Spain, the 2 Seville locations already at 42C at 2pm. Given Seville's longitude and (wrong) timezone 2pm is actually not even midday there. The real heat usually peaks around 5pm locally.

Nothing special in France yet. 35C in a few places.

When I try to get info for my closest weather station on the Met Office website it comes up with one that's miles away even though it lists one that's virtually round the corner.

Could be but with a slight NE breeze and Gosport fleetlands being on the NE coast of Gosport it might be a tight call. At least the humidity is down on yesterday a little with DP around 16/17 rather than 19.4 of yesterday. 

Temperatures have dropped slightly to 28C.

The same here there are 2 within 12 miles of me but only one with public access. Gopsort fleetlands is probably the closest to me at around 3 crow mile's however there is a lot of open water between us. This station was a couple year's ago available on a website which has since gone offline, and the metoffice don't publish data from unless it's the hotspot. So I am reliant on thorney which almost 12 miles away well away from the urban heat island Portsmouth/Gosport.
