The climate of Eastern Ontario is humid continental with large seasonal variation. Snow and ice are dominant during the winter season. Summers are fairly warm and humid, usually lasting a little longer than winter does. The average July maximum temperature is 27C (80F). Temperatures rarely exceed 35C (95F), but during periods of hot weather, high humidity is often an aggravating factor.

Spring and fall are changabale seasons, prone to extremes in temperature and unpredictable swings in conditions. So when you visit here, make sure you bring clothes that can be worn in layers. Cornwall is generally a flat plain, dotted with some extensive woodlots and marshes, but is primarily farmland.
