There are several places in Argentina where twon peaks of precipitation occur during both spring and autumn, albeit not as elegantly distributed as in the likes of Lyon and Bologna:
Neuquén - March and October are the wettest months
Paso de los Libres - April, March and October are the wettest months
La_Plata - March and October are the wettest months
Across the world, this is particularly great:
Nairobi
However, it's an equatorial located at 1ºS, so the calendar autumn and spring are the times where the sun is highest in the sky. Nevertheless, it's interesting to see how
intense are both wet seasons and both dry seasons.
