🇫🇮 Helsinki vs 🇫🇷 Paris

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.

Semi-oceanic — mild with four distinct seasons, regular rainfall

Paris has a pleasant climate with warm summers and cool winters. Spring and fall are the most popular seasons for a reason — mild temperatures, manageable crowds, and the city at its most photogenic. Summers can have heat waves; winters are cold but rarely harsh.
