A record day for southern Quebec? Why not; The beautiful province is not a record, this season! Indeed, the maximums scheduled for this Thursday are very close to records recorded in the past on July 24 … What does that mean? Well, yes, some sectors could really be particularly hot, on this fairly humid day!
When breaking records is almost commonplace
Temperatures of 33 ° and 34 ° are planned, this Thursday, for sectors of southern Quebec, notably the large region of Montreal and Gatineau (also Ottawa).
Another day that promises to be hot and, since breaking heat records seems to be the new standard for several Quebec regions, now it would still be possible today. Montreal is very close to beat its maximum temperature record, for a July 24, 33.3 °, a record that dates back 62 years.
Montreal: the major heat region
We can therefore say that Quebec thermometers should long remember the summer of 2025! “What is impressive with the 2025 summer season, so far, is the quantity of days with a 30 ° mercury for southern Quebec. It is still temperatures above normal and that we have been able to observe during many days, ”underlines Alexis Vazquez, meteorologist. By exceeding again 30 ° this Thursday, Montreal would find itself even more above the average meteorological summer … And we agree that we still have all the month of August to have potential 30 ° and more!
As of July 23, the metropolis was entitled to 12 days with a mercury of 30 ° and more, since the beginning of the year. Its average is however 10.3 days per year with such a mercury (data recorded between 1991 and 2020).
Note that when we talk about normal meteorological summer, it is the data between early June and the end of August that are taken into consideration.
A sequence to the rhythm of air conditioners
The continuation of things? The south of Quebec has not finished sweating, while feeling above 35 are already on the program four times rather than one, in the next seven days. Next Monday, another wet index of 40 could even be in the plans.
