When to go
From the 2026 climate study, not the live forecast.Peak summer 20–22°C with the Baltic light running near-endless in June. Suomenlinna sea fortress, the island saunas, the design district. Its continental position means the odd 27–29°C spell, but the sea and the islands keep it breathable.
