Update May 5, 2024 at 9:00 p.m.
It is not only the length of daylight that is increasing, but also the intensity of UV rays. A danger that should not be taken lightly. Details.
In short :
Coincidence
Monday will mark the arrival of a new season: solar summer. This will bring day length to its peak at the next solstice, as well as the intensity of UV rays to their maximum for nearly three months.
Between May 6 and August 5, the position of the sun in the sky becomes precarious: its rays are stronger and can burn the skin more easily and quickly.
Good to know: solar summer offers up to 750 hours of possible sunshine. This is almost three times longer than solar winter which only offers a maximum of 268 hours.
The return of solar summer is timely: Quebec will be entitled to two beautiful days at the start of the week.
Monday and Tuesday, temperatures above 20 degrees Celsius are forecast for southern Quebec, under generally clear skies. In total, Montreal could receive up to 7 hours of sunshine during the day on Monday and up to 11 hours the next day. Abitibi-Témiscamingue could even receive up to 13 hours of sunshine on Tuesday. A sunbath that will do you good.
Risk factor
We’ve always been told that sunscreen is the best ally against sunburn. However, it is not only during the days of July that you need to be careful: the UV rays of May are just as powerful as those of August.
During the solar summer, the maximum UV index is essentially at a very high level, between the eighth and the tenth on a scale of 11 steps. At such intensity, the skin can burn quickly during unprotected sun exposure.
