    If you believe that the weekends are sunny are rare, you’re not wrong. A single end of the week was not marred by rain since the month of may in the greater Montreal area.

    Flurries fell on the city for at least one of the two days of the weekend over the past 10 weeks, except Saturday and Sunday 29 and 30 July.

    Before this date, it is necessary to go back to the weekend of 27 and 28 may to consider the last time the sun was at the rendezvous for two days, according to data from the weather network.

    Not finished

    And it is not finished. This weekend, the umbrella will always be required, as 5 to 10 mm of rain are expected today and about 1 mm tomorrow.

    The summer is not particularly warm either. For the first time since the year 2000, the mercury has not reached 30 °C in the month of July in Montreal, reports Frederick Boulay, meteorologist at the weather network.

    One thing is for certain, the rainy weather makes many unhappy, and starting with the motorcyclists.

    “It is sure that it is less enjoyable,” concedes Jean-Pierre Fréchette, director-general of the Fédération motocycliste du Québec, which itself has had to postpone some of the outputs on the road because of the rain.

    “But there are buffs that do are not private to the hiking trips that they had planned this summer,” he said. […] It is enough to be well equipped. “

    Day Camp to the fleet

    In the day camps, the whims of mother Nature, they have often complicated the activities.

    “When it rains, it retrieves the groups in the interior, but it’s necessary to reprogram it. And for the children, it is easier to let go of their crazy and spend their energy on the outside than when they are confined to the interior, ” says Barbara Poinsaut, director of communications at camp Sports Montréal.

    The meteorologist Gilles’brien says that the rain and the end of the week is not attributed to chance. The air pollution would also have a role to play.

    “People are more likely to take their car during the week, and from Thursday, there is an accumulation of pollutants in the atmosphere,” he says. Then, they fall as precipitation because the water droplets collect around these particles and create clouds. “

    “It is for this reason that precipitation tends to fall more on the weekends, even in winter,” he adds.

    Major cities

    This phenomenon concerns especially the large cities, especially those located in the corridor between Toronto and Montreal.

    A study from the University of Arizona carried out in 1998 even concludes that in the coastal regions of the United States, the average rainfall of the Saturdays is 22 % higher than Monday. Other research, however, have questioned these results.

    According to Denis Thibodeau, a meteorologist for Environment Canada, such a correlation between pollution and rainfall does not exist.

    “Of course, if you are on leave the end of the week, you’re going to notice more if it’s raining,” he stressed. […] But the weather doesn’t know if it’s Monday or Sunday. “
