The Montreal weather has been quite unpredictable in April, so much that we were surprised with 15 centimetres of snow in the middle of spring. Mhm, remember that? Well, it seems as if the Montreal weather forecast is looking up for the month of May. With spring in full force, and summer less than a month away, Montrealers can finally expect some nice and sunny days this month I mean the saying does go "April showers bring May flowers!"
