You should only use record highs from one station when compiling averages. If one station in a city reached a higher temperature, there's no harm in mentioning it.

Goes by 'Piikkio Yltoinen' in ogimet. The muncipality of Piikkiö merged with Kaarina some years ago and the station is known as Kaarina. Synop report summary

Kaarina is the neighbouring city and Salo centre is a 56 km driving distance from Turku centre. So they are not within city limits. But surely can be counted as "metro area" at least if you ask LA Mex. Or B87.

Northolt is within London's city limits though.

But at the end of the month or year would you post the average high from station 1 because it's highest, the average low from station 2 because it's highest, record high from station 3 because it's highest? This seems wrong.

Indeed, to be consistent and to refer the same station is a very good idea- as well all averages and longer time statistics are based on a one station data, not on mix data of stations A, B and C.
My second closest official station recorded an above 20c recording a almost a month ago, I liked it too but i did not "use" it.

You can compile averages for more than one station. Cities like London, LA and Chicago are huge so it's understandable that one station does not represent everywhere.

The closest weather stations to me are Heathrow, Kew, Hampton and Northolt. I use Heathrow for all reports, but will mention other stations if anything of note happened.
End of month summary is always from Heathrow, however.

Which is absolutely fine. Averages should be used from one station, as they will vary, certainly in a city the size of London. And specific events eg reaching 21c, can be used from any station within the city.
Obviously if you use Heathrow for all your readings, then cherrypick a warmer one on a warm day, then that's wrong, but you haven't done that so I don't see the problem.
As the thread is about London and not specifically Heathrow, I really don't see the problem.

Imagine Heathrow reaches 25C high in May, but another station reaches 28C. At the end of the month, would you use the averages from Heathrow and the absolute maximum from the other station?

All the stats would be from Heathrow, but the other station might get a mention, separate from the official summary.
