Abstract: The wind force on the sea is often estimated by visual observation, using the Beaufort wind scale as standard. To know the fidelity of the visual observation, we examined the wind forces determined with a wind gauge (true wind force) for 261 cases in which visual estimates were wind force 3 (from 6.5 to 10.5 knots in wind velocity). The visual estimates agreed with the true wind force for about 80% of the data. Although the wind force tended to be underestimated in fair winds and overestimated in adverse wind, the visual observation was accurate enough for practical work.
