During fog, precipitation, and smoke events, visibility is reduced and can make travel difficult and sometimes dangerous. The National Weather Service reports visibility from their stations throughout the United States. So, on a clear, dry day, how far can you see? This is topic of Phillip’s Weather Trivia today.

The answer is 10 miles. 10 mile visibility is considered maximum visibility by the National Weather Service. While some can see mountains and other high objects farther away, basic objects on the horizon get lost beyond 10 miles, mainly because the curvature of the Earth drops them below the horizon. Boats which are more than 10 miles off the coast cannot see the shore unless the shore has mountains or tall buildings. - Phillip Williams
