Question 1185Navigation General

The correct answer is B) swells. Wind direction can be determined by observing whitecaps, waves, and low clouds, but not swells. Swells are long, rolling waves that are not directly influenced by the current wind, but rather by wind conditions from a distant location. While swells can provide some indication of overall weather patterns, they do not directly reflect the wind direction at the current location, which is the information needed to determine wind direction. The other answer choices - whitecaps, waves, and low clouds - are all good indicators of the wind direction at the current location.
