Sunshine hours per day
The number of hours of sunshine refers to the time when the sun is actually visible. That is, without any obstruction of visibility by clouds, fog or mountains. With 9 hours per day, July is the sunniest month in the region of Quebec. In December, the sun shines the least.
Rain days per month
A rain day is a day on which at least 0.1 mm precipitation (=0.1 liter) per square meter falls. This can be rain, snow, hail or even dew. So it does not have to rain the whole day. With 13 rain days, December offers the most rain days, while September has the fewest.
Precipitation amount in mm/day
The amount of precipitation is measured in millimeters per square meter. Thus, at two mm/day, two liters of water fall on one square meter within 24 hours. With only 2.3 mm, the least amount of rain falls in March. October, on the other hand, has the most rain.
Relative humidity in %
Warm air can absorb more moisture than cold air. The relative humidity indicates how much moisture can be physically contained in the air. At high humidity, a person feels uncomfortable and perceives this as oppressive. In general, a relative humidity of 40-60% feels pleasant. With only 66% humidity on average, it is quite dry in May. The highest value of 80% is experienced here in November.
Absolute humidity in g/m³
In warm months, there is also a higher absolute humidity almost everywhere. At a temperature of 25°C, air can absorb up to 23 grams of water per cubic meter. At 20°C, it is only 17.3 grams. A relative humidity of 40% at 25°C thus corresponds to an absolute humidity of 9.2 grams of water. From a proportion of approx. 13.5 grams, humans perceive the air as muggy.
