More than 9 hours of daily sunshine! This is one of the data that emerges from the September weather report for the Jura, as shown by measurements from the Dole Tavaux station. That’s a total of 272 hours of sunshine, much more than normal for this month. As a direct result, the average maximum temperature (maximum temperature measured for each of the 30 days of the month) reaches 27.6°. According to MeteoNews, an absolute record in the Jura. “This is 6.1° more than the average normally observed for the month of September and this fully corresponds to an additional summer month with an average similar to June or August.” The monthly record was set on September 5th at 33, 8° measured.
Another “hot flash” next weekend.
Because the nights are longer, the difference in the lowest average temperatures is smaller. However, these remain 2.6° higher than usual in September.
And when it comes to rainfall, the statistics are just as meaningful. The average monthly rainfall in Dole during September is usually 68.8 mm. This year the total is just over half, 36mm.
And this month of October begins with similar trends. This Monday, October 2nd, MeteoNews recorded 28 degrees in Dole. A temperature that will continue for part of this Tuesday before falling again with the arrival of a much more temperate air mass. However, the 8 to 12 degrees in the morning and 18 to 20 degrees in the early afternoon will certainly be in line with seasonal norms. And from Friday, according to forecasters, a new “heat wave” will hit the Jura, “probably with temperatures above 25 degrees”.
“Canadian haze”: no risk of pollution
Since this weekend we have been observing a fog phenomenon over part of the Upper Jurassic that is not natural but is directly linked to the forest fires that are raging in Canada and have devastated around 700,000 hectares. A yellowish haze that is actually the visible part of the circulation of fine particles carried to us by air currents.
With health risks? No, answers MeteoNews and explains that these particles are transported by high-altitude currents between 2,000 and 3,000 meters and do not sink to ground level. In terms of public health, the forecast institute estimates that the consequences could only be “marginal”.
Thanks to the change in weather on Tuesday, this “Canadian haze” is expected to dissipate in the coming hours.
