Toronto, the capital of Ontario, Canada, experiences a continental climate (Köppen climate classification Dfa). The weather is characterized by long, extremely cold winters and short, warm, and humid summers. Toronto's climate is largely influenced by its placement on the Ontario River, making the winters and summers more tolerable under the circumstances.

Spring comes to Toronto from mid-March to May and has varied weather. It starts off cold and freezing with frequent snowfall and frost. Transition happens in the first few weeks that are adjacent to winter. Gradually, the weather warms up but with an occasional return of the cold weather. Most days remain fairly sunny and mildly warm, but occasionally there are rainy afternoons accompanied by light thunderstorms.

Summer lasts from June to August and is usually warm and very humid. While some days are sweltering and muggy, some days are tolerable and cool. The temperature is high during summer, occasionally going over 30°C (86°F) on the hottest days. Summer also experiences reasonably higher rainfall compared with the other seasons.

Autumn in Toronto lasts from September to mid-November. The weather transitions between warm, pleasant, and sunny days in the first few weeks and freezing days and nights as winter nears. Tourists frequent Toronto in autumn more because of the warm sunny days and the moderate rainfall that allows perfect touring.

Winter is the longest season in Toronto, lasting from November to mid-March. The weather remains freezing with frequent snowfall and occasional snowstorms. The temperature hovers below the freezing point, and sometimes glaze ice occurs - freezing everything in Toronto from trees, roads, and cars. Winter has icy winds, the blizzards that have a high gust, and can cause extensive damage.
