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 Karlby gästhamn
Known for sailing, by the OpenStreetMap map of the area. The shore faces SW, so wind from the NE 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 SW. Wind from the SW blows onshore, wind from the NE blows out to sea, and wind from the NW or SE runs along the shore. It is exposed 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 17°C in August, its warmest (3/2 wetsuit). For sailing at intermediate level the best month is usually August, with about 6 good days in 7; in January and December, about 4. From the weather of past years. The town to stay in is Kökar. Within 5 km we also list 2 wind sports spots.
