🇫🇮 Helsinki vs 🇨🇦 Toronto

Helsinki's climate is shaped by its peninsular position jutting into the Gulf of Finland, where the Baltic Sea moderates temperatures year-round — keeping winters milder and summers cooler than inland Finland. The city's complex coastline of bays, islands, and headlands creates pronounced microclimate variation, with exposed southern shores subject to maritime winds while sheltered inland valleys trap cold air in winter. Sea ice formation in late winter can temporarily shift coastal districts toward a more continental climate until the ice breaks up in spring.

Humid continental — cold winters, warm summers, lake-effect snow

Toronto's climate is shaped by Lake Ontario. Summers are warm and humid; winters are cold and snowy, though less extreme than Chicago. The western Toronto waterfront gets more lake-effect snow. Fall is beautiful with foliage.
