San Juan del Sur Wind Stats

The rose diagram shows how commonly and how strongly the wind blows from different directions through a typical August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to San Juan del Sur, located 31 km away (19 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common wind at San Juan del Sur blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at San Juan del Sur. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 18% of the time (6 days each August) and blows offshore 83% of the time (26 days in an average August). During a typical August wind stronger than >40kph (25mph) was expected for only a single days at San Juan del Sur
