The Valposchiavo can be divided into three distinct climate zones. The first spans from the Bernina Pass at 2328 meters (7,637 ft) down to Cavaglia and Sfazu and includes the two Alpine plateaus La Rösa on the pass road at 1870 meters (6,135 ft) and Cavaglia at 1693 meters (5,554 ft) on the railway line. The second zone is relatively flat and extends from the hamlet of Pedemonte north of Poschiavo at 1100 meters (3,608 ft) to Poschiavo itself, Lake Poschiavo and Miralago at 965 meters (3,166 ft). The third and steeper zone includes the Municipality of Brusio in the lower valley and spans from Miralago down to the Italian border at Campocologno at 553 meters (1,749 ft).
