🇫🇮 Helsinki vs 🇵🇹 Lisbon

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.

Mediterranean — hot dry summers, mild wet winters, abundant sunshine

Lisbon is one of Europe's sunniest capitals with 2,800+ hours of sunshine annually. Summers are hot and dry; winters are mild. The Atlantic coast provides cooling breezes. The 2017–2024 tourism boom makes summer extremely crowded.
