Air about 25°C during summer. Cold in winter. A wetsuit is almost always needed, summer a short or on hot days just shorts. Winter is possible to ride, but very cold and it can freeze.
From Karlskrona take E22 towards Kalmar for about 15 min. Pass Loesen and about 5 min behind Loesen exit and follow signs to Torhamn. Once the street splits, don't drive to the harbor, but drive to the natural reserve. Follow the dirt road all the way to the end into the park. Park and walk for about 200m until you see the water.
