Because the province of Quebec stretches over a large geographic region, it is not possible to pin down one single climate for the entire area. It is helpful to think of the province as being split into three separate sections, each with its own climate.
Southern Quebec experiences all four seasons, with hot summers, cold, snowy winters and lots of rain year-round. This is the kind of climate that an individual traveling to Quebec would most likely encounter, because this area is the most populated part of the province.
Central Quebec has long, cold winters and short, cool summers.
Northern Quebec experiences an Arctic climate, which is characterized by frigid winters that last about 8 months, and a continuous layer of permafrost.
