Monthly and seasonal summaries
This page shows monthly and seasonal weather summaries including an analysis of general conditions as well as a summary of significant weather events.
April was slightly colder than normal (1 to 2 degrees below normal), except along the St. Lawrence River and south of the river where temperatures were near normal. On the scale of days, the number of days where temperature reached 10 degrees over southwestern Quebec was 30% lower than normal. For example, in Montreal, there were five days instead of eight.
Total precipitation (rain and water equivalent of snow) was well above normal everywhere (30 to 60%), with a maximum in the Laurentians of Quebec and Montreal (twice normal), except in the extreme East, the far North and the Gaspé region where it was 20 to 40% below normal. Note that the north-south pattern described by the map is due to the fact that the weather trajectories followed this corridor during the month.
Significant weather events:
- April 8 : 15 to 30 mm of rain fell in 24 hours over southern Quebec. Rain and snow melt water caused two landslides in the Laurentians and Mauricie, and flooding of 104 municipalities which required the evacuation of nearly 2,200 people.
- 13-16 April: 40 to 80 mm of rain fell in areas north of the St. Lawrence River, and 25 to 50 mm elsewhere. The largest amount was recorded in the Réserve faunique des Laurentides, where 90 mm fell in three days, which represents 90 % of the monthly normal.
- April 14: Temperatures of 23 to 28 degrees were recorded in southwestern Quebec, which are 10 to 15 degrees above normal. A temperature of 20 C in Montreal before April 15, returns, on average, every 7 years since 1872.
- 22-23 April : 20 to 40 mm of rain fell north of the St-Lawrence, and from 10 to 20 mm in the south. Minor flooding of homes and businesses, as well as road closures, was reported in the Eastern Townships and the Montérégie.
- 23-25 April : The Gaspé region received 30-60 mm of precipitation (rain and water equivalent of snow), causing the flooding of 22 homes and few roads.
- 30 April-01 May: : 25 to 45 mm of rain fell over southwestern Quebec, particularly in the Greater Montreal, Montérégie and Lanaudière.
