All things related to rain are welcome. Want to post a weather forecast? A puddle? A raindrop on a window? Does it look like it might rain soon? Or it just finished? We love the rain, and we welcome it all.
The city in europe with the most rain is Bergen, in Norway, with ~250 a year(195 ≥1mm, Manchester gets 142 ≥1mm). And they apparently get two months straight with constant rain every day and night sometimes.
Manchester gets on average 828mm of rain a year, Bern gets 1022mm and Bergen gets 2412mm.
It's not even close to being a standout.
Although fun fact, Capel Curig in Wales gets more downfall(and arguably rain) every year at 2697mm over 206 days(≥1mm), but Cetinje in Montenegro wins with 3300mm over 136 days(≥1mm). It's insane over a few months(Nov->Feb/Jan)
