About Lighthouse Atlas

Lighthouse Atlas is a directory and map of lighthouses in the United States and Canada. For every lighthouse with a page it shows the position on a map and, for key dates in 2027, when the sun sets there, when civil dusk ends and in which direction the sun goes down.

What we show

1,427 lighthouses are listed across the United States and Canada. Each lighthouse with its own page has its position on a map, how finely the position was recorded and a sunset table for the solstices, the equinoxes and the 15th of every month in 2027, in the local time of the lighthouse. States, provinces, counties and towns have pages once at least three of their lighthouses have one. Every listed lighthouse is on the map.

How to read the sun times

• Times are calculated from the map position for a flat sea horizon at sea level. Hills, buildings, trees and weather change what you see on site.
• “Civil dusk” is when the sun is 6 degrees below the horizon.
• “Sun sets toward” is the direction in degrees from true north: 270° is due west.
• These are sun times, not visiting hours.
• Distances are straight lines from your position, not driving or walking routes.

Before you go: access, hours, tours and tickets are not listed here. Some lights stand on breakwaters, islands or private land - check locally.

What we do not show

• Whether a lighthouse can be visited, and any opening hours, tours, tickets or fees.
• Whether the tower can be climbed, its height, age or light characteristics.
• Photos of the lighthouses themselves: the photos on this site are illustrative.

Pages appear in stages

The site is published in batches. A lighthouse gets its own page when its batch is released, and a state, province, county or town gets a page once at least three of its lighthouses have one.
