Calgary experiences a humid continental climate with warm summers and icy winters, with the mercury often dropping below freezing. The mountains in and around the city cause dry conditions, but summers (June to August) do bring a little rainfall.
Winters (December to February) are long and cold, but are occasionally relieved by warm winds called Chinooks. Average daily temperatures in Calgary are 62°F (17°C) in summer and 20°F (-7°C) in winter. The weather in Calgary fluctuates considerably and the daily predictions are often off the mark.
