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 Iate Clube Barra de Sao Joao
Known for sailing, by the OpenStreetMap map of the area. The shore faces E, so wind from the W blows out to sea (our estimate from the coastline).
Water about 23°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
A harbour, as OpenStreetMap maps it, on a shore facing E. Wind from the E blows onshore, wind from the W blows out to sea, and wind from the S or N 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 21°C in August, its coldest month (2 mm shorty), and 25°C in March, its warmest (no wetsuit). For sailing at expert level the best months are usually August, September and October, with about 2 good days in 7. From the weather of past years. The town to stay in is Rio das Ostras.
