The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by dark blue. It is based on 2160 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Puerto Vallarta Rivermouth, located 28 km away (17 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Puerto Vallarta Rivermouth blows from the W.
