Climate Overview
Chicago
Humid continental — cold harsh winters, hot humid summers, severe storms
Chicago lives up to its Windy City nickname. Lake Michigan creates its own microclimate — cooler summers and heavier lake-effect snow in winter. Summers are warm but brief; winters are among the harshest of any major American city.
Helsinki
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.
