If you ask people around here in summer what a hot day is the answer is pretty much 90F. Even the weather forecasters would never call 85F a "hot" day. Lol they call it "warm" or comfortable. Never is a day below 90F called "hot" around here at least. Of course I'm talking about forecasts in summer and not other seasons. In April or May they likely will call 85F "hot".
This is a local tv forecast from last July. If 85F avg July high temp is "hot" then what would you call the July avg high in Columbia SC in July, or Jackson, MS "very hot". The hottest a climate can be according to Koppen is "hot summer". And I certainly don't believe Philadelphia falls in that category when places in the South have avg high temps in the low 90'sF. They are hot, we are just very warm.
That 3 days 90°+ is based on NYC. And of course it varies elsewhere. Otherwise May 1st to October 12th would be a 165 day long heatwave here every year
Here the standard is 3 days+ with highs 110°F/43.3°C+
London summers certainly aren't "hot", excluding heatwaves I that can be be almost unbearable by high humidity, I'd classify a typical day in London as "warm". Although I'm sure this has been discussed on here many times before.
Wellington has a summer warmer than Portsmouth and a winter warmer than Nice, plus 600 hours more sunshine than London.
Wellington often seems to be portrayed as some sort of hellish climate.
London gets a worst 'rap' weather wise than any other place on the planet, usually by idiots who don't actually live anywhere near the place and do nothing but quote ridiculously out of date stereotypical nonsense as their reasoning. London is NO WHERE NEAR the worlds worst climate, in fact it has the best major city climate in the whole of Northern Europe, you think Moscow is nicer? Yeah well you will think again the next time your car doesn't start because its frozen solid or the next time you have to shovel 6 feet of snow to get your car out the drive, you will think again the next time you have to f*ck about changing tyres just because the season's changed. I was in Zagreb some years ago over Christmas and it was so damn cold I couldn't even stay out for longer than 20 minutes at a time and even then I was wearing two pairs of everything, London felt rather bloody pleasant when I got back I can tell you. In London you can go out and enjoy the 'outside' at any time of year, I cycle to work year round, in some places on this planet the weather KILLS, not in London. Anybody that 'thinks' London has a bad climate don't know what they are talking about.
Most people would consider partly cloudy and 24c 'warm'. Maybe the lower end of warm (23-29c), but still warm.
Even dhdh, who hated the London climate before he arrived, now admits it is nowhere near as bad as it's made out to be, and the summers are actually alright.
24C is round up by 0.5C+for your warmest month in summer. June is only 21.0C and Aug 23.2C, and in the US that would be one of the coolest places so no, it wouldn't really be considered warm here. Add the fact that you get only 621 hours of sun, that would certainly be a poor summer by US standards.

Same here. I agree. Philly (39.9N) would be considered warm/very warm during the summer with an avg summer max of 85F/29.4C. Chicago/MDW (41.8N) is about 2.2F cooler at 82.8F/28.2C and IKK (41.4N) near where I live 1.4F cooler at 83.6F/28.7C
London/Heathrow only has a 3 month avg max of 22.6C. So if I consider Chicago to have "warm" summers but is still around 5.5C+ warmer than London, then of course London would be considered cool by my standards.
Number of days at or above 86F/30C+
Philly: 54 max 87 days in 1991 (since 1940)
Chicago/MDW: 44 max 73 days in 1983 (since 1981)
IKK: 45 max 83 days in 1988 (since 1981)

I'd say that threshold is a bit too low even for us, 90°F / 32°C is only a few degrees above average. July 2010 had an average high of 91°F / 33°C.
I think 95°F / 35°C would be more appropriate.
