🇫🇮 Helsinki vs 🇯🇵 Tokyo

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 subtropical — distinct four seasons, hot humid summers, mild winters

Tokyo has dramatic seasonal swings. Cherry blossom season (late March–April) and autumn foliage (October–November) are spectacular. Summers are brutally hot and humid with typhoon risk. Winters are mild and dry with occasional snow.
