After reaching its peak between July 19 and 29, the decline in summer is well started in Quebec. Nevertheless, This means that even if a few very hot days are still in front of us. Nevertheless, the trend will inevitably go to more bearable conditions in August.
According to meteorologist Patrick Duplessis, the coming days could however reserve some surprises in terms of heat. Additionally, Nevertheless, “If we look at the temperatures over the next 14 days. Moreover, we observe values around 29 to 30 degrees, therefore close to the heat wave. However, We could even have one. For example, two heat waves from August 3, with a fairly hot and potentially humid trend at times, until the middle of the month. »»
Less sun. less heat – Great decline accelerates quebec
Despite great decline accelerates quebec these last summer upheavals, statistical reality is clear: the climate peak of summer is now behind for the majority of Quebec regions. “In northern Quebec, the peak of heat is around July 29 to 31. But elsewhere, this period has already passed, ”specifies Patrick Duplessis.
This drop in temperatures naturally coincides with the rapid decrease in hours of sunshine. The month of August marks a significant turning point: “We lose approximately 85 minutes of duration of the day between the beginning. the end of August, and this pace accelerates even more in September, as we approach the equinox”, underlines the meteorologist.
Between August 1 and 31, Quebec should lose between 3 and 4 ° C in terms of average maximum, which will bring us at 24 ° C at the end of the month in Montreal and 21 ° C in Gaspé.
Return of fresh nights
This shortening of the days leads to an increase in the frequency of fresh nights, that is to be under 12 ° C in Montreal, particularly from the second week of August. “Even if this year seems to be slightly deviating from the usual climatic trend. there is something inevitable in this gradual drop in temperatures,” adds Patrick Duplessis.
Thus, although the first weeks of August can still present very hot days, at 30 ° C or beyond, the rapid decrease in the intensity of solar radiation and the duration of the day will necessarily contribute to making the climate more comfortable over the month.
