The climate of Ontario is continental and the province experiences hot summers and very cold winters with snowfall. Spring and autumn tend to be milder, and due to the Great Lakes, the province experiences far less of a variation in its temperatures year round, as well as more precipitation than would be expected for such a central region. Cities futher aweay from the Lakes in the south of the province are much hotter and temperatures can range in the upper 80s Fahrenheit (in the 30s Celsius), with possible heat waves. In winter, areas north of the Great Lakes tend to be much colder, with more severe winters caused by Arctic air currents and temperatures can range between 36°F and 14°F (0°C and -10°C). Fortunately the major cities are geared for the cold with indoor shopping arcades, underground walkways and indoor sports venues.
