Typical, not a forecast. Reanalysis wind misses some local thermal winds, so a spot known for an afternoon breeze may do better than this.

About Tvärminne hamn
Known for sailing, by the OpenStreetMap map of the area. The shore faces SE, so wind from the NW blows out to sea (our estimate from the coastline).
Water about 8°C: 5/4 or 6/5, hood, boots and gloves. Typical sea temperature for the time of year, not a forecast.
A harbour, as OpenStreetMap maps it, on a shore facing SE. Wind from the SE blows onshore, wind from the NW blows out to sea, and wind from the SW or NE runs along the shore. It is sheltered to the open sea. We found no boat hire, sailing school or club within 10 km on the map, so bring your own boat here. The sea is about 2°C in February, its coldest month (5/4 or 6/5, hood, boots and gloves), and 18°C in August, its warmest (2 mm shorty). The town to stay in is Hanko.
The score is the conditions only: the journey, the price and the partners never change it (how we score, how we earn).
Rough cost (estimate): about US$1,310–US$2,460 each
about US$1,310–US$2,460 each · 6 nights, 2 sharing: flights, hire car, stay, food.
