About Lauttasaari in April
Lauttasaari's island geography means it is surrounded by open water on nearly all sides, resulting in a distinctly maritime microclimate with delayed spring warming, milder autumn temperatures, and persistent sea fog in late spring. The island's relatively low-rise residential fabric allows sea breezes to penetrate deeply, reducing summer heat island effects significantly compared to the mainland core.
