Mobile Bay (Dauphin Island) tide chart for today and solunar table

What are the tides like in Mobile Bay (Dauphin Island)?

Dauphin Island sits at the mouth of Mobile Bay, Alabama. The tide is diurnal and small: one high and one low most days, with the timing shifting by roughly an hour a day.

Based on the station's constants, Mobile Bay (Dauphin Island) has a diurnal tide: the form number (K1+O1)/(M2+S2) is 11.68. The reference spring range — around new and full moon — is about 0.7 ft, and mean sea level sits 0.6 ft above MLLW. That is why the two high tides (or the two lows) on the same day are often noticeably different in height.

What is the best time to fish in Mobile Bay (Dauphin Island)?

Solunar theory points to the major periods (about 2 hours centered on the moon passing overhead or underfoot) and the minor periods (1 hour around moonrise and moonset). What surf, pier and inshore anglers repeat most often is simpler: moving water (the middle of the incoming or outgoing tide), low light (dawn and dusk) and a moon near new or full, when the tidal range is biggest.

The fishing score from 0 to 4 combines those three signals. It is a traditional rule of thumb, not a catch forecast: it knows nothing about wind, rain, water clarity or the species you are after. In November 2026, the top-scoring days at Mobile Bay (Dauphin Island) are November 23, November 24, and November 25.

Where does this data come from?

The prediction adds up 27 harmonic constituents for NOAA station 8735180 — Dauphin Island, published by NOAA CO-OPS (Averaged 5 years LSQHA (2019-2023). Sa and SSa from 17 years (2007-2023)). Phases are referenced to Greenwich (GMT) and converted to local time for each date, including daylight saving time. Heights are relative to MLLW from the station's 1983-2001 tidal datum epoch. Node factors follow Schureman; sun and moon positions use Meeus's formulas.

Wind, pressure and storms change the real water level, sometimes by a foot or more. Times shift much less than heights.
