how far can you see from the beach

The distance you can see from a beach depends on several factors:

1. Visibility Conditions: On a clear day, the curvature of the Earth limits the distance you can see. The formula to calculate the horizon distance is:

   [
   d \approx 3.57 \times \sqrt{h}
   ]

   where ( d ) is the distance in kilometers and ( h ) is the height of your eyes above sea level in meters. For example, at eye level (about 1.7 meters), you can see about 4.7 kilometers.

2. Obstructions: Buildings, trees, or other obstacles can block your view.

3. Weather: Fog, haze, or mist can reduce visibility significantly.

4. Elevation: If you’re on a taller structure (e.g., a dune or a building), you can see farther.

In ideal conditions, you might see several kilometers across the water, but in practice, obstructions and weather often limit this.
