About Kaartinkaupunki in May
Kaartinkaupunki's dense stone block architecture and proximity to the South Harbour create Helsinki's most pronounced urban heat island, with nighttime temperatures staying 2–3°C warmer than surrounding areas. The district's south-facing waterfront exposure brings direct Baltic sea breezes that moderate summer heat but amplify wind chill in winter storms.
