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.
