The 5 Warmest Places In Finland For Balmy Scandinavian Trips
While Finland may conjure images of snow-covered landscapes and frigid temperatures, several regions offer surprisingly warm summer getaways.
Lappeenranta leads Finland’s heat index with a record 36 days above 25°C in 2024, benefiting from Lake Saimaa’s thermal stability.
Heinola and Kuopio tied for the national high temperature (31.4°C) in June 2024, with Heinola’s valley location blocking cooling winds.
Kuopio consistently delivers 19-22°C summer days, enhanced by its inland position near Lake Kallavesi.
Helsinki, despite coastal breezes, maintains 18°C averages with extended 19-hour summer daylight. For a unique experience, consider taking a day trip to nearby islands where clear water conditions rival some of the Mediterranean’s snorkeling destinations.
Lahti rounds out the list with reliable 18°C+ temperatures and reduced rainfall compared to coastal areas.
