Best fishing times at Mayport Naval Station, Degausing Structure
The bite score (0 to 100) adds up what anglers watch most: moving water (a tide running harder than usual here scores higher), solunar periods (major periods of about two hours centred on the moon overhead or underfoot, minor periods of about an hour on moonrise and moonset), dawn and dusk light, and how close it is to the new or full moon. Best times are the stretches of the day scoring near that day's top.

About the tides at Mayport Naval Station, Degausing Structure
Mayport Naval Station, Degausing Structure gets two high tides and two low tides almost every day, and the two highs are close in height. Over the next month the water typically rises or falls about 4.7 ft between a high and the next low.
The biggest swings in this window come around Tuesday, October 27, when the day's range reaches 6.7 ft, and again around Sunday, October 11 (5.9 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Sunday, October 18, with only 3.3 ft between the day's highest and lowest water.
The lowest tide of the month is -0.1 ft at 3:06 AM on Tuesday, October 27. There are 2 minus tides (lows below the chart's zero line) in this window: the best times for tide pools, clamming and walking the flats.
The highest predicted tide is 6.5 ft at 9:34 AM on Tuesday, October 27. Onshore wind or a storm can push the real water level above that.
This is a reference (harmonic) station: NOAA predicts its tides directly from years of measured water levels here, which makes it among the most reliable predictions on the coast.
