How this rating works
Solunar theory says fish feed more when the moon is overhead or underfoot (major periods, about 2 hours) and around moonrise and moonset (minor periods, about 1 hour). We score each day from 1 to 10 by checking when those periods happen, using the NOAA tide predictions for station 8773896 and the sun times for this spot:
| Base | every day starts at 1 | 1 |
|---|---|---|
| Sunrise / sunset | a period overlaps sunrise or sunset ±1 h: major +2, minor +1 (max 3) (Moon overhead × sunset +2) | 2 |
| Tide | a NOAA high or low falls inside a period (tide change): major +2, minor +1; moving water during a major period (no high/low within 1 h of it) +1 (max 4) (Moon overhead – tide change +2) | 2 |
| Moon phase | within 2 days of a new or full moon +2, within 4 days +1 (today: 4.4 days) | 0 |
| Today | 5, rounded | 5/10 |
1–3 poor · 4–5 fair · 6–7 good · 8–10 excellent. Solunar times are a rule of thumb, not a guarantee: weather, water temperature and bait matter a lot. Tide changes and moving water are specific to this station, so nearby spots can score differently.
Solunar periods calculated for 28.36, -96.58 (moon times from astronomical equations, local time). Not a fishing forecast.

Shoalwater Flats, Espiritu Santo Bay has a diurnal tide: one high tide and one low tide on most days (only 9% of days have two high tides). The average rise or fall between high and low tide is 0.2 ft, growing to about 0.3 ft at spring tides (around new and full moon) and shrinking to about 0.1 ft at neap tides (around the quarter moons). The highest tide predicted in the next 12 months is 0.4 ft on December 25, 2026 at 3:49 AM; the lowest is -0.1 ft on November 26, 2026 at 2:47 PM, and 92 low tides in that period drop below zero (MLLW).
