What visual cue indicates visibility is restricted due to weather conditions?

Visibility is significantly impacted by weather conditions, and fog or heavy mist is a classic visual cue of such restricted visibility. When fog or mist is present, it reduces the distance at which objects can be seen, affecting the ability of boaters to navigate safely. This condition can create hazardous situations on the water, as it obscures landmarks, other vessels, and navigational aids, making it essential for boaters to be aware and take precautions.

Clear skies would typically indicate that visibility is good, while a marked traffic route is related to navigation rather than visibility itself. Obstructions from land could limit sightlines but do not directly indicate weather-related visibility issues. Recognizing fog or heavy mist as a cue for impaired visibility allows boaters to adjust their speed and ensure greater safety on the water.
