Best fishing times at Boot Key Harbor bridge, Boot Key
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 Boot Key Harbor bridge, Boot Key
Boot Key Harbor bridge, Boot Key gets two high tides and two low tides most days, but one high is clearly higher than the other (and one low clearly lower), which is called a mixed tide. Over the next month the water typically rises or falls about 1.7 ft between a high and the next low.
The biggest swings in this window come around Wednesday, October 28, when the day's range reaches 2.9 ft, and again around Monday, November 9 (2.5 ft). Here the biggest ranges depend on the moon's phase and on how far north or south of the equator it is, so they don't always line up with the new and full moon. The calmest day is Tuesday, October 20, with only 1.6 ft between the day's highest and lowest water.
The lowest tide of the month is 0.0 ft at 5:12 AM on Wednesday, October 28. 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 2.9 ft at 10:46 PM on Wednesday, October 28. Onshore wind or a storm can push the real water level above that.
This is a subordinate station: NOAA calculates its times and heights by adjusting a nearby reference station, so expect them to be a few minutes or a few tenths of a foot off on any given day.
