Solunar Charts


What is a solunar chart?

A solunar chart is a table that many fisherman use to help determine which days of the month and what times of the day are best for catching fish. Solunar charts are based on the solunar theory. According to the solunar theory, fish move depending on the moons location. The solunar table tracks the moons position, but not the position of the sun.

The only role the sun plays in the solunar theory is in regards to the tide. This theory was established back in 1926 by John Alden Knight, but it is believed to have been used by fisherman for many years before becoming officially published. For a fisherman, the sunrise, sunset and tides are the most helpful times of day for a fish to bite. These charts really help fisherman determine whether the moon is overhead or directly underfoot.


The strongest fish activity for fisherman is during a full moon, or new moon. The weakest activity occurs when there is only a three quarter moon or a quarter moon. And this is due to the fact that the sun and the moons gravitational force is its strongest when directly below or above our head. Using a solunar chart will ensure that your fishing trip is not a complete waste of time.

Thanks to the latest U.S. Naval Observatory’s technology and GPS technology, lunar data received is more accurate and beneficial to fisherman than ever before. When comparing solunar chart and table data on various websites, you should always verify this information regularly with the U.S. Naval Observatory. Any inconsistencies could result in false information and few or no bites.
