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 8723949 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 – tide change +2; 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 24.73, -81.02 (moon times from astronomical equations, local time). Not a fishing forecast.

About the tide at Fat Deer Key, Florida Bay
NOAA station 8723949 is 0.5 mi east of Marathon, FL, the nearest beach or town with its own page here. Its predictions are NOAA time and height offsets from reference station Key West (8724580, 51 mi west).
