In Paris, early spring is much, much cooler than late autumn, so much so that people here are talking of "Indian summer", sometimes until mid -November, whereas weather remains chilly in Paris at least until end of April. You can wear summer clothes in Paris in October but not in April.

Um no, November is cooler than March. December is also a tad chillier than February, though they're essentially the same. October is indeed warmer than April, but that's not early spring / late autumn anymore.

Late autumn is a lot warmer than early spring.

Observatory Hill averages 20.6/12.5 in May and 21.2/12.0 in September, so not that different really. September is much more likely to see 30C+ though.

A lot of people on this thread seem to be going based off memory instead of actual stats. What a surprise that a thread where a bunch of non-regulars post that would happen.

I would like to see a European map which shows the November-March temperature differences, I can't see a clear pattern. Maritime places are warmer in late autumn but continental places like Kiev Minsk or Volgograd aren't the opposite. The places with the warmest March in comparision to November seem to be around the Alps... Bolzano, Milan, Freiburg etc. I wonder what causes that?

That's hard to say. Our weather is pretty erratic. We can be in the middle 80's one day and 60's the next in both spring and fall. We can also be in the 70's on Thanksgiving, although that's very rare. I guess I'd have to say that early spring just feels warmer when temperatures are in the 40's after your body is used to the 20's and below in winter.

Here are the actual figures for Heathrow. Max / Min / Mean

November is warmer, though March is drier and sunnier.
