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 8767403 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 underfoot – moving water +1; Moonrise – tide change +1; Moon overhead – moving water +1) | 3 |
| Moon phase | within 2 days of a new or full moon +2, within 4 days +1 (today: 4.4 days) | 0 |
| Today | 6, rounded | 6/10 |
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 29.77, -93.01 (moon times from astronomical equations, local time). Not a fishing forecast.

About the tide at Mermentau River, Grand Chenier
It is a harmonic reference station (predicted directly from its own tidal constituents).
Mermentau River, Grand Chenier has a mixed semidiurnal tide: usually two highs and two lows a day, of noticeably unequal height (on average the day's two highs differ by 0.3 ft and its two lows by 1.1 ft). The average rise or fall between high and low tide is 1.2 ft, growing to about 2.4 ft at spring tides (around new and full moon) and shrinking to about 1.2 ft at neap tides (around the quarter moons). The highest tide predicted in the next 12 months is 2.6 ft on October 27, 2026 at 6:18 PM; the lowest is -1.5 ft on January 21, 2027 at 8:18 AM, and 187 low tides in that period drop below zero (MLLW).
