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 1633227 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 15.23, 145.74 (moon times from astronomical equations, local time). Not a fishing forecast.
