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 9755679 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) | 0 |
| 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) | 0 |
| Moon phase | within 2 days of a new or full moon +2, within 4 days +1 (today: 4.4 days) | 0 |
| Today | 1, rounded | 1/10 |
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 17.93, -66.16 (moon times from astronomical equations, local time). Not a fishing forecast.

About the tide at Las Mareas
It is a harmonic reference station (predicted directly from its own tidal constituents).
Las Mareas has a diurnal tide: one high tide and one low tide on most days (only 10% of days have two high tides). The average rise or fall between high and low tide is 0.7 ft, growing to about 1.0 ft at spring tides (around new and full moon) and shrinking to about 0.4 ft at neap tides (around the quarter moons). The highest tide predicted in the next 12 months is 1.1 ft on December 23, 2026 at 10:37 AM; the lowest is -0.3 ft on December 24, 2026 at 12:05 AM, and 196 low tides in that period drop below zero (MLLW).
