How to use solunar fishing times
Solunar theory, first published by John Alden Knight in 1926, ties fish and game activity to the position of the moon. Fish feed hardest during two major periods each day, when the moon is directly overhead or directly underfoot, and two shorter minor periods around moonrise and moonset. The times above are calculated for Santa Isabel's exact coordinates.
The effect is strongest around the new and full moon. It stacks with the obvious low-light windows: fish often feed at dawn and dusk too, and when a solunar period lands right at sunrise or sunset, that's your best shot. In saltwater, add the tide — a running tide near a solunar period is prime. Cross-reference the feeding periods, the sun and moon times, and the Santa Isabel tide chart above, then plan around the overlaps.
None of it beats being on the water, and weather can shut a good bite right down — always check the Santa Isabel marine forecast before you launch.
Frequently asked
When is the best time to fish in Santa Isabel today?+
Tuesday, July 21 rates fair for fishing at Santa Isabel. The strongest windows are the major periods (5:25 PM–7:25 PM and 5:10 AM–7:10 AM) around the moon overhead and underfoot, plus the minor periods around moonrise and moonset. Dawn (6:00 AM) and dusk (7:03 PM) are also prime, especially when they line up with a solunar period.
What are major and minor feeding times?+
Solunar theory ties fish activity to the moon. Major periods are roughly two-hour windows when the moon is directly overhead or underfoot — the peaks. Minor periods are about an hour around moonrise and moonset. Fish tend to feed hardest in these windows.
Does the moon phase affect fishing?+
Yes. Fishing generally rates best around the new moon and full moon, when the sun and moon pull together for the strongest solunar effect and the biggest tides. Today's moon is first quarter (52% lit).
Is high or low tide better for fishing at Santa Isabel?+
In saltwater, moving water matters more than high vs low — fish feed on a running tide, so the hours either side of a high or low are often best. Overlay the tide times below with the solunar periods, and fish where both line up.
What is the best fishing day this week in Santa Isabel?+
Sun, Jul 26 rates very good (waxing gibbous), the strongest day in the 7-day outlook below.
