Most of Edmonton's attractions are in operation year-round. July and August are the warmest months, when temperatures usually range from a low of 56 F/12 C to a high of 75 F/24 C. It can get hotter, but humidity is fairly low, so the heat is comfortable. Nights are generally cool, so take a sweater or jacket. In the summer, it stays light until nearly midnight.
December and January bring most of Edmonton's snow (the average annual snowfall is 54 in/137 cm), but the cold is more severe than the snowfall. Temperatures drop below 0 F/-18 C and rise to 17-21 F/-11 to -7 C in January and February. Edmontonians have made winter more bearable by providing underground transit and enclosed overhead and underground walkways in the downtown area.
