Thank you, thank you very much for giving your answer! I am most close myself to this option too - judging by the impression this visual gives to me.
ps.
Here, autumn is most associated with rains. Also - you might find curious another detail that is helpful: as @tatdt noted, most folks wear light dress - which is not the case for the Spring; it is not warm as the Summer, so folks are in no hurry to take off their warm winter clothes, at least most do it slowly :) and this is also a mark.
