The average warmest day of the year at Heathrow is 32.5, so yes, it does. You have to go back to 1993 to find a summer that didn't reach 30c, even the rubbish of 07 and 08 reached 30c. Botev lives in Seattle, which is barely warmer than London in summer, by 0.05c, and has never even visited, so he's talking pure, grade A ****.
32.5? I'm sure someone worked it out before as 30. Something.

Looking at this map (B87 posted this once), to me it seems that Heathrow is indeed in an Urban Heat Island. Not in the center of it, but still influenced
Interestingly Greenwich is closer to the center (it's in the red zone), and I don't see a big difference in temps between that station and Heathrow

I have looked at metoffice data for 51 years between the 50's and 2014.
The average date of the first 27°C in this time was June 17th, so far later than the late May that some posters were suggesting. The average date of the first 27°C between 1981-2010 was June 16th, very much the same.
There was only one year in which 27°C was not reached, and that was 1974.
In the 51 year period there were 4 years in which 27°C was not reached until August, giving a 7.3% chance that any year will not reach 27°C by that time.

Well he asked if London reaches 90 degrees every summer. The answer is no. I said London does not even reach 30C every summer, and that is also true. It's rare for that to happen, but it does happen.
We have had a year without a 90 degree temp too, but that was back in 1875

The city has logged only one summer since 1871 that did not see a 90-degree day. That was in 1875, when the official temperatures were taken downtown close to Lake Michigan’s cooling breezes. The hottest readings that summer were 89 degrees on June 11 and 88 on July 15, so it is almost certain that inland areas did reach 90.
Over the last 30 years, the average highest temperature at Heathrow is 31.7C. So no, it doesn't reach 90F every year as B87 claims.
5 of the last 30 years have failed to reach 30C, with the lowest being 28.4C, and the highest 37.9C. Only 3 of those years have seen the temperature exceed 35C too.

So what do you mean exactly, he's been exaggerating London's climate to make it sound warmer than it really is?! And he's just been caught? No more credibility?

30C is not too shabby given the latitude. And that was only 5 years out of 30. Would the same happen in other areas of England? I'm curious just how warm London is compared to the rest of the country.
I'd be curious how different the temp stats would be at Gatwick given it is in that green area around London and not in the yellow or red.

From the looks of it, the average highs are about 0.5C cooler, but the lows are about 2C cooler than Heathrow or Greenwich. Probably fewer days with 30C temps

No it's not too bad. Nowhere outside of the south east can match those temperature's. The average high in the warmest month at my nearest station is 21.2C.
Between 2000 and 2014, our average high temperature is 29.1C.

2 summers haven't seen 30C the past 15 years.
