We were incredibly lucky at the start of the week, and because the second half of April was warm and mild—and the buds have emerged on the tree branches. It was warm, the weather was beautiful, and we almost lost track of time.
Unfortunately, the rest of this week will be rainy and a bit cooler, with highs of 18 degrees, 10 degrees, 7 degrees… and the weather in Montreal will be miserable until next Tuesday (May 6, 2026).
The region, already thoroughly soaked by the snowmelt, is set to receive nearly 70 mm of rain, and Montreal will be under a cold rain on Thursday, April 30—with a high of 9 degrees. We’ll have lost 11 degrees Celsius in temperature compared to Monday afternoon…
On Friday, May 1, the midpoint between the spring equinox and the summer solstice, the weather will be half sunny, half rainy, with a high of 9 degrees Celsius.
Weather forecast for May 2026 in Montreal
In May, it will truly be spring— “In May, do as you please”—and the weather will feel more like spring after a rather exhausting back-and-forth between winter and spring. But spring in Quebec isn’t like spring in the English countryside or spring in the South, with its sweet scent of flowers warmed by the sun. The weather will be cool, and the flowers will bloom on sunny days.
According to The Weather Channel, May 2026 is going to be a bit chaotic in Montreal. When the weather is nice, it’s going to be really nice. And when it rains, the rain will be heavy and accompanied by strong winds.
Temperatures will rise by about 10 degrees Celsius during the month of May, going from 8 degrees at the end of April to highs of 19 degrees by the end of May.
