Sources and notes
- All values are Environment and Climate Change Canada Canadian Climate Normals 1991–2020. "High" and "low" are the mean daily maximum and mean daily minimum for the month; precipitation is total water equivalent (rain plus melted snow).
- Eureka has the lowest annual mean temperature and the least precipitation of any Canadian weather station. Alert is a composite of three Alert stations (Climate IDs 2400300/2400305/2400306).
- Lytton's precipitation normals are from the 1981–2010 period, and Osoyoos's precipitation is from the nearby Osoyoos West station (1981–2010), because 1991–2020 precipitation was not published for those stations.
- Record highs and lows span each station's full period of record: Lytton 1921–present, Osoyoos 1954–present, Windsor Airport 1940–2020, Eureka 1947–present, Alert 1950–present, Yellowknife 1942–present.
