About Katakai Port
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 22°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
A spot for sailing, 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 exposed to the open sea. The sea is about 16°C in February, its coldest month (3/2 wetsuit), and 26°C in August, its warmest (no wetsuit). For sailing at expert level the best months are usually March and April, with about 4 good days in 7; in June, July and December, about 2. From the weather of past years. The town to stay in is Funabashi. Within 5 km we also list 1 surf spot.
