Solunar fishing & hunting in Castro Valley
Anglers and hunters around Castro Valley, California plan by the moon: two major feeding periods when the moon is directly overhead and underfoot, and two shorter minor periods at moonrise and moonset. Every window in the table above is calculated for Castro Valley's exact position — 37.71°, -122.06° — and its local clock, not a generic statewide chart. Because Castro Valley sits toward the western edge of its Los Angeles time zone, the sun and moon run roughly 8 minutes later here than the clock implies — so solar noon, and the overhead major period that tends to track near it, fall about 8 minutes later than a one-size-fits-all national table would tell you.
At 37.71° latitude, daylight in Castro Valley swings from about 14.6 hours around the June solstice to roughly 9.4 hours near the December solstice — a moderate 5.2-hour seasonal spread. That matters because a solunar period does its best work when it overlaps first or last light: the long days of summer push Castro Valley's dawn and dusk far apart and give more chances for a major or minor to land on a low sun, while short winter days compress the action into a tight morning-and-evening window. Watch the table for periods flagged Dawn/Dusk — in Castro Valley those are the windows worth rearranging your day around.
Whatever Castro Valley anglers are targeting, lining trips up with the feeding windows above is the cheapest edge available. The waters around Castro Valley — a community of roughly 65,001 people — see the same rhythm move both rod and rifle: the major and minor periods that switch on the bite also get deer and other game on their feet, especially when a period falls in the cool hours near sunrise or sunset. Pair the day ratings above with local weather, water temperature, barometric trend, and the season, and use the 7-day outlook to line your next Castro Valley trip up with the strongest days.
