Did a google search for the temp but with no success. Anybody any idea?
It's still pretty cold which is not surprising as the maggia carries melting water from the mountains. According to the official data temperatures are between 12-15 degrees. http://www.hydrodaten.admin.ch/it/me...emperatur.html
Btw be careful where you go swimming. Especially close to the ponte brolla there are dangerous eddies that can suck you down. A lot of people have drowned there.
Thanks. A good guide. The Maggia is probably similar temp.
