sudden shock
Exceptional heat characterized the weekend and broke many records. The communities of Sherbrooke and Mont-Tremblant also experienced their hottest August 6 and 7 on record.
record cold
The days follow each other but are not the same: Monday, these are cold records that could be broken almost anywhere in the province. Montreal, for example, is in a good position to bring a new brand to the board.

Responsible for this trend reversal is the passage of a cold front that hit Quebec on Sunday. It effectively encouraged the formation of an atmospheric trough, thereby opening the door to a cooler air mass. The arrival of a system and its imposing cloud cover will contribute to this particularly chilly start to the week. Temperatures are therefore likely to remain below seasonal norms for the remainder of the week. The dew point is also much lower as humidity lingers after crossing the cold front. The impression of freshness persists, especially early in the morning. This freshness kick, paired with a rather shy sun, gives a touch of autumn next week. In fact, autumn weather is often marked by an increased presence of clouds and a drop in mercury.
Remember that the normals are now on a downward slope. From August 15, the average temperature decreases by 1°C per week. Here are the normal values by region from August 1st to August 31st:
- Gaspe: 25°C to 21°C
- Sept-Iles: 21°C to 17°C
- Rimouski: 23°C to 19°C
- Saguenay: 24°C to 21°C
- Quebec and Sherbrooke: 25°C to 22°C
- Montreal and Gatineau: 27°C to 24°C
- Val d’Or: 23°C to 20°C
Regardless, a more heat-friendly course is possible for the end of August. Temperatures could rise above seasonal norms again.
