Tampa Bay is big enough that it doesn't move as one piece of water. This planner runs off NOAA's Old Port Tampa station near the bay's mouth, close enough to the main channel and the Skyway for most trips, but worth a second thought if you're headed up into Old Tampa Bay or Hillsborough Bay, more on that below.
Open the tide planner for Old Port TampaPre-set to NOAA station 8726607. Set your depth and hours, get your days.The bay has three or four distinct arms, Old Tampa Bay to the northwest, Hillsborough Bay by downtown, and the main stem running south past the Interbay Peninsula out toward the Skyway. Tide timing can lag by twenty or thirty minutes the further up an arm you go, since it takes time for the water to push that far in and pull back out. If you're launching well up in Old Tampa Bay near Safety Harbor, treat this planner's times as a starting point and expect your local high or low to land a bit later than what's shown.
The main ship channel carries plenty of water at any tide stage, so depth usually isn't the issue there, current and traffic are. Where the tide actually matters most for boaters is getting in and out of the shallower side areas: the flats off Weedon Island, the stretch up the Alafia River, and Cockroach Bay to the south, all of which can go from comfortable to uncomfortably thin within a couple hours of a falling tide.
Ramps are spread across the whole bay rather than clustered in one spot, which is part of what makes Tampa bigger to plan around than a single-inlet spot like Sarasota. Picnic Island and Ballast Point on the Tampa side, Cypress Point further north near Old Tampa Bay, and E.G. Simmons Park and Bahia Beach down toward the south end near Apollo Beach. Which one makes sense depends entirely on which part of the bay you're headed to, there's no single ramp that's central to all of it.
Old Port Tampa (NOAA station 8726607) is a harmonic reference station with its own gauge at 27.858°N, 82.553°W, reporting real time water levels as part of NOAA's PORTS network. Predictions here are computed directly rather than derived from somewhere else.
It also has the largest tidal range of the three places covered here. Mean range is 1.73 ft and the great diurnal range is 2.48 ft, against 0.82 ft and 1.41 ft up in Gasparilla Sound. Mean higher high water sits at 2.48 ft above MLLW. More water moves through Tampa Bay on each tide, which means stronger current in the cuts and a bigger penalty for getting the timing wrong.
The gauge also records what weather can do. The highest astronomical tide ever predicted here is 3.31 ft. The highest level actually observed is 9.31 ft, on 27 September 2024. The lowest observed is -4.31 ft, on 29 September 2022. Both were hurricanes, and between them they span nearly fourteen feet against a predicted range of four and a half. That gap is the whole reason a tide prediction is a starting point rather than an answer.
