About the tide in Sebastian Inlet
Sebastian Inlet is the only opening to the Atlantic for roughly fifty miles of the Indian River Lagoon, which makes it one of the most tide-dominated pieces of water in Florida. Everything that drains a very large, very shallow lagoon has to squeeze through one narrow cut under the bridge — and the current that produces is the reason the inlet is famous for both its fishing and its reputation for catching people out.
The tide range here is modest — this is Florida, not Maine — but range is not the point at Sebastian. The point is volume through a bottleneck. A lagoon system tens of miles long exchanges water through a cut a few hundred feet wide, so the current at the bridge routinely runs harder than the tide height alone would suggest, and it keeps running for a while after the turn.
That matters two ways. For anglers, the moving water is the whole game: the outgoing tide sweeps bait out of the lagoon and stacks predators in the inlet, which is why snook season and a strong ebb are talked about in the same sentence here. For anyone running a boat through, an ebb against an onshore easterly wind builds a short, steep, breaking sea right in the mouth — the classic Sebastian hazard, and the reason to time a transit for slack or a flood.
Note also that lagoon water levels behind the inlet respond to wind as much as to tide. A hard sustained blow can hold water in or push it out of the Indian River independently of the astronomical prediction below.
Sebastian Inlet tide questions
What time is high tide in Sebastian Inlet today?
High tide in Sebastian Inlet today is at 8:16 am (3.0 ft) and 8:24 pm (2.8 ft).
What time is low tide in Sebastian Inlet today?
Low tide in Sebastian Inlet today is at 1:57 am (0.1 ft) and 2:23 pm (0.5 ft).
What is the tide range in Sebastian Inlet?
Today's range in Sebastian Inlet — the difference between the day's highest high and lowest low — is 2.9 ft. The average over the next two weeks is 2.0 ft, so today is above-average. Range varies through the month on the spring–neap cycle.
Is this week a spring tide or a neap tide in Sebastian Inlet?
This week is a spring tide period in Sebastian Inlet — predicted daily ranges are at or near their largest of the cycle. Spring tides bring the largest ranges and the strongest currents; neap tides the smallest. This is worked out from the predicted water levels themselves rather than from moon phase, which does not always line up — especially on the Gulf coast.
How many tides a day does Sebastian Inlet get?
Sebastian Inlet has a semi-diurnal tide: two high tides and two low tides every day, roughly equal in height, about six hours apart.
What time is sunrise and sunset in Sebastian Inlet today?
Sunrise in Sebastian Inlet today is at 7:19 am and sunset is at 6:57 pm. The moon is new moon, 0% illuminated.
What tide datum are these Sebastian Inlet heights measured from?
All heights on this page are in feet above MLLW (mean lower low water), the standard chart datum used by NOAA for US tide predictions. A predicted height of 0.0 ft means water at the datum, not a dry bottom — and negative predictions do occur on the biggest spring lows.
How accurate are these Sebastian Inlet tide predictions?
They are astronomical predictions from NOAA harmonic constituents for the Sebastian Inlet bridge station, which is the same basis NOAA publishes its own tables on. They account for the motion of the sun and moon but not for weather. Sustained wind, barometric pressure and river flow can all push real water levels above or below the prediction, sometimes by a foot or more in a strong blow.
What tide is best for fishing Sebastian Inlet?
Most local fishing centers on moving water rather than a particular stage, but the outgoing (ebb) tide has the strongest reputation at Sebastian because it pulls baitfish out of the Indian River Lagoon and concentrates predators in the inlet. The last two hours of the ebb and the turn are widely worked. Slack water is generally the slowest period.
Is the tide at Sebastian Inlet the same as in the Indian River Lagoon?
No. The lagoon behind the inlet is large and shallow, and its water level lags the ocean tide substantially and is strongly affected by wind. The times on this page are for the inlet at the bridge — expect the tide inside the lagoon to arrive later and with a much smaller range.
Can I get tides and a marine forecast for my own spot near Sebastian Inlet?
Yes. The free SeaLegs AI app gives tide predictions plus wind, wave and an AI-rated GO / CAUTION / NO-GO call for any spot you drop a pin on — not just listed stations.
What is the water temperature in Sebastian Inlet today?
As of October 10, 2026, the satellite-measured sea surface temperature near Sebastian Inlet is about 84°F, and it has held steady over the past 6 days. The water temperature readings on this page come from the SeaLegs AI DeepCast satellite pipeline and are refreshed every morning.
