The climate of Ontario varies by season and location. [19] It is affected by three air sources: cold, dry, arctic air from the north (dominant factor during the winter months, and for a longer part of the year in far northern Ontario); Pacific polar air crossing in from the western Canadian Prairies/US Northern Plains ; and warm, moist air from ...

Today, the most commonly used climate map is the Köppen climate classification, developed by Russian climatologist of German descent and amateur botanist Wladimir Köppen (1846–1940), which divides the world into five major climate regions, based on average annual precipitation, average monthly precipitation, and average monthly temperature.
The climate of Hamilton is humid continental (Dfa type) and relatively mild compared with most Canadian cities. The average January temperature is −5 °C (23.0 °F) downtown, but many days rise just above freezing often making for slushy conditions during snowfalls. [ 19 ]
The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
