I've been there, it felt obviously in the city and not outlying. Not really city center, but still rather urban. Is there any official station closer? Is Greenwich closer? Somehow Greenwich felt further out to me and a bit more separate from London.
I was in London for a few days 15 years ago. I don't remember much about the layout of the city to be honest. I was there for a wedding before we made our way to Greece.
Looks like Heathrow may not see an 80 until the end of June or early July?
Eh, how on earth can anybody argue that it hasn't hit 80F in London when an official met office station that is actually closer to the centre of London than Heathrow has recorded it? The title of this thread isn't 'When will Heathrow reach 80F'
Loads of other users on here, particularly the American ones use multiple stations for their cities - most of all LA-Mex. London may not have a great deal of micro climates, but certainly they do exist and for such a large city there are bound to be differences across the city. People could easily use the warmest station - London WC - to claim that central London averages 5C lows in January and 15.5C lows in July, but nobody regularly quotes that station as far as I know.
Heathrow is hardly even representative of what I would call central London anyway, where tourists would actually visit. I live 5 minutes away from it and the area is very green and not a huge urban UHI zone.

Have you ever seen a heat island map for london? Heathrow is right in the dark red along with the city center...

St James' Park is right in the centre of London, but in a big park, that is an offical Met Office station too...

That data is for one day..
I have posted this many times, I live right next to the place and it isn't a substantially built up area, it is surrounded by reservoirs (one of which is right near to my house) only to the east is it really built up, and even then it is just houses and shops, nothing more than a few stories high. Like a small town basically. If you went and looked around the area, and then went to central London with the much larger buildings and skyscrapers that are densely packed together, anybody with a basic weather knowledge would be able to see that the UHI factor would be much higher there.
Somebody even worked out 20 years worth of averages for London WC, and although it is 10 years short of data for it to really be 100% reliable, it shows minima averaging above 5C in January, and 15.5C in July. If you look on the UHI thread I also posted data from London City station for August 1995, where 1/3 of the days had 20C+ lows, compared to a few in Heathrow.
That heat island map for 8th August 2003 that people love to use to try and prove that Heathrow is in the UHI has one flaw. All it shows is a front; Farnborough which is to the SW but the same distance from Heathrow as High Wycombe, recorded the same temperature as Heathrow. Farnborough is certainly not part of any UHI under any circumstances.
Heat islands have no effect during the day. Heathrow is obviously a few degrees cooler than central at night.
This is a true heat island map. Heathrow is around the 0/+1 boundary.

I live near Heathrow, practically right next to it yet people try and tell me that it is this massive urban zone with a huge UHI!
Would be interesting if there was a station right in the centre though..

Everything has to be consistent. For example, someone from LA could use downtown data for their high temperatures in the summer because they are the warmest, but use the low temperatures for their airport because they are the warmest. Guess what, it doesn't work that way.

But nobody has been doing that here, yet people kick up a fuss. When it happens for NYC, LA or Chicago, nobody cares.
