The sea is warmer, around 21°C atm in Biarritz, though it's still pretty cool so I don't think it's the reason why they can get hotter. Under a southerly flow the air doesn't travel over sea before reaching Biarritz. Also it's currently 23°C at 850 hPa over Biarritz, 24°C further east over places like Pau. Don't think it has ever gotten that warm over Se England? Bordeaux is quite a ways inland, separated from the sea by miles of sandy pine crops that heat up quickly. The places that reached 38°C today are like this:

Also they're close to Spain, so that helps. The 2003 heatwave proved that coastal England can be the hottest part of the country when the wind doesn't come from the sea. Thinking of northern Kent, places like Sittingbourne.

37.8°C sounds hot as well to me! I don't really have any preference. I agree with your point about triple digits, though I like having negative readings below freezing. If I had grown up in the US, I think it would be hard to prefer the Celsius scale though, as it's less precise not using decimals. That's why I much prefer millimeters to inches for rainfall. I'm not really familiar with inches despite all these years on the weather forum.

Yeah that seems likely.. the 850 hPa do get quite high down there and as you say it doesn't actually travel over water!

I'm not sure about our 850s, they do go above 20C, I think August 2003 they may have approached 24C but I am not sure

Must be unusual in July.

August 2006 was warmer in London than it was in Paris.

It was a terrible month, but it was even worse in Paris.

21.6C in Paris, 22.3C in London.

Wow. North Texas getting several times the monthly average rainfall in one day...



Clusters of slow-moving thunderstorms dumped heavy rains on North Texas Thursday morning, forcing authorities to close Interstate 35 for several hours near the Red River.

Several swift water rescues were reported in Cooke County Thursday morning where more than 10 inches of rain had fallen.

“It’s been raining cats and dogs since 12:30 this morning, “ said Shell Service Station employee John Davis in Valley View. The station, at 13965 Interstate 35, had standing water in it Thursday morning. “My rain gauge shows 11.6 inches of rain.”

Interstate 35 was closed near Valley View for several hours Thursday morning and nearby Farm Road 922 was also closed because of high waters, Texas Department of Public Safety officials said.

Shortly after 8 a.m., officials with the Texas Department of Transportation said that I-35 had been reopened, but “travel was unreliable because of floodwaters - seek alternate routes.”

The National Weather Service in Fort Worth reported 10.78 inches of rain as of 6:30 a.m. just south of Valley View, and 8.11 inches had fallen near Alvord in Wise County.

Flash flood warnings were in effect Thursday for Cooke, Wise and Denton counties. The warnings extend into Friday for Denton and Wise.

Humidex. Yeah sure feels like 40°C+ in coastal northern Brittany.
That looks like Heat Waves in the Baltimore-DC corridor. What are the dew points like. Upper 70's-low 80's ?

Not even that apart from a few isolated locations. The heat index for those 40C humidex readings is 35C. Unfortunately no heat index map is available. Here's the current dew point map:
