Solunar feeding forecast · California · 37.793°, -122.315°
Fish feed hardest during these solunar windows. Times are local to Alameda Naval Air Station.
~2 hours around the moon overhead and underfoot.
~1 hour around moonrise and moonset.
Plan ahead — solunar rating, feeding periods, and the moon for the week.
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 Alameda Naval Air Station'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 Alameda Naval Air Station 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 Alameda Naval Air Station marine forecast before you launch.
Tuesday, July 21 rates fair for fishing at Alameda Naval Air Station. The strongest windows are the major periods (6:15 PM–8:15 PM and 6:00 AM–8:00 AM) around the moon overhead and underfoot, plus the minor periods around moonrise and moonset. Dawn (6:04 AM) and dusk (8:27 PM) are also prime, especially when they line up with a solunar period.
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.
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 (53% lit).
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.
Sun, Jul 26 rates very good (waxing gibbous), the strongest day in the 7-day outlook below.
