Field notes
Humid continental (Ontario) — Canada's coldest national capital. Winter (December–February, -7 to -10°C average) brings continuous snow accumulation; January regularly drops below -25°C. Summer (June–August, 19–21°C average) is warm humid and pleasant. Spring (April–May) is rapid transition; autumn (September–October) brings the cleanest shoulder-window foliage colors.
