Precipitations in winter

Precipitations in summer

Mean of observed winter and summer temperatures (above) and precipitations (below), 1961-1990, according to the databank of the National Land and Water Information Service (NLWIS) at Agriculture and Agri-Food Canada, based on weather station observations from the archives of Environment Canada, interpolated on a grid with 10 km resolution.

In the recent past (1960-2005), the climate of Quebec has changed significantly. Daily mean temperatures in southern Quebec increased by 0.2°C to 0.4°C each decade¹. This warming was greater for average night-time temperatures than for daytime temperatures ^{1 2 3}. The increase in temperatures was also evident in related climatic variables, such as a shortened frost season, an increase in the number of growing degree-days and a decrease in the number of heating degree-days¹.

In terms of precipitation, we have experienced an increase in the number of days with low-intensity precipitation³ as well as changes in solid precipitation, which has diminished in southern Quebec, but increased in the North⁴.
