- Mosquitoes are at their most active in August, particularly around the Aura River and forested areas of Ruissalo Island during evening hours
Best Activities in August
Turku Archipelago Island Hopping
August offers the most reliable ferry schedules and warmest water temperatures for exploring Finland's southwest archipelago. Islands like Ruissalo, Naantali, and the outer skerries are accessible with full summer timetables. Water temperature reaches 18°C (64°F) - warmest of the year for swimming. Long daylight hours mean you can catch late ferries back to mainland.
Medieval Turku Castle Evening Tours
August's extended daylight allows for special evening tours of Turku Castle that run until 8pm, impossible during darker months. The castle's medieval chambers stay naturally cool during warm August days, providing comfortable exploration. Special summer exhibitions and medieval dinner events take advantage of the season.
Aura River Cycling and Waterfront Dining
August's warm evenings and minimal darkness make riverside cycling ideal. The 15 km (9.3 mile) Aura River trail connects downtown to the archipelago, with numerous outdoor terraces and beer gardens operating full summer schedules. Many restaurants extend outdoor seating hours until 10pm in August.
Ruissalo Island Nature Trails and Beach Activities
Ruissalo's 13 km (8.1 miles) of hiking trails are at their most accessible in August with dry conditions and full daylight until 9:30pm. The island's beaches offer Finland's warmest swimming conditions at 18°C (64°F) water temperature. August is peak season for the island's oak forests and wildflower meadows.
Turku Market Square Food Tours
August brings peak season for local produce at Turku's 800-year-old Market Square. New potatoes, berries, and fresh fish are at their seasonal best. Extended summer market hours (7am-6pm vs 9am-3pm in winter) and numerous outdoor food stalls create ideal conditions for food tours.
Naantali Spa Town and Old Town Walking
August's warm weather makes the 20 km (12.4 mile) journey to historic Naantali ideal for combining spa treatments with old town exploration. The medieval wooden houses and Naantali Church are best appreciated during long summer evenings. Spa facilities offer outdoor treatments only during summer months.
