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 8459338 and the sun times for this spot:

Baseevery day starts at 11
Sunrise / sunseta period overlaps sunrise or sunset ±1 h: major +2, minor +1 (max 3) (Moonset × sunrise +1; Moonrise × sunset +1)2
Tidea 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) (Moonset – tide change +1)1
Moon phasewithin 2 days of a new or full moon +2, within 4 days +1 (today: 0.5 days)2
Today6, rounded6/10

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 41.19, -71.57 (moon times from astronomical equations, local time). Not a fishing forecast.
