About the tide in Jacksonville Beach
Jacksonville Beach fronts the open Atlantic just south of the St. Johns River entrance at Mayport, on a stretch of northeast Florida coast that runs one of the state's larger tide ranges — commonly four to five feet. For a beach town that is a big number: it is the difference between a wide, hard, walkable sand flat and almost no beach at all.
This is textbook semi-diurnal water — two highs and two lows daily, close to equal, about six hours between each turn. The rhythm is regular enough that locals plan around it without thinking, and the range is large enough that it genuinely changes the shoreline through the day.
At low tide the beach at Jax Beach opens up into a broad flat that is the best of the day for walking, running, shelling and surf fishing the troughs. At high tide the water comes well up the slope and in places reaches the dune line. Surfers watch it too — the sandbars here work differently through the tide cycle, and a break that is flat at high water can turn on as the tide drops.
North of town, the St. Johns River entrance at Mayport concentrates all of this into a working inlet with commercial and naval traffic. The same four-to-five-foot range that makes the beach pleasant makes the river mouth run hard, and an ebb against an onshore northeast wind is the standard local warning there — the same pattern as St. Augustine and Ponce, for the same reason.
Jacksonville Beach tide questions
What time is high tide in Jacksonville Beach today?
High tide in Jacksonville Beach today is at 8:21 am (6.5 ft) and 8:39 pm (5.7 ft). The 8:21 am high of 6.5 ft is the larger of the two — that difference between the day's two highs is called diurnal inequality and is normal here.
What time is low tide in Jacksonville Beach today?
Low tide in Jacksonville Beach today is at 2:11 am (0.2 ft) and 2:46 pm (0.4 ft).
What is the tide range in Jacksonville Beach?
Today's range in Jacksonville Beach — the difference between the day's highest high and lowest low — is 6.3 ft. The average over the next two weeks is 4.8 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 Jacksonville Beach?
This week is a spring tide period in Jacksonville Beach — 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 Jacksonville Beach get?
Jacksonville Beach has a mixed semi-diurnal tide: two highs and two lows a day, but the two highs are noticeably unequal — averaging about 1.1 ft apart. That inequality is normal and predictable.
What time is sunrise and sunset in Jacksonville Beach today?
Sunrise in Jacksonville Beach today is at 7:24 am and sunset is at 7:00 pm. The moon is new moon, 0% illuminated.
What tide datum are these Jacksonville Beach 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 Jacksonville Beach tide predictions?
They are astronomical predictions from NOAA harmonic constituents for the Jacksonville Beach 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 surf fishing at Jacksonville Beach?
Most local surf fishing works the moving water either side of low tide, when the troughs and cuts between the sandbars are exposed and readable and fish move in to feed along them. An incoming tide over a trough you scouted at low water is a widely used approach. Slack high is generally the slowest period.
Is the tide at Jacksonville Beach the same as at Mayport or downtown Jacksonville?
Mayport, at the St. Johns River entrance a few miles north, runs very close to the beach times. Downtown Jacksonville is a different matter — it sits well up the river and the tide arrives substantially later there with a noticeably reduced range. The times on this page are for the oceanfront.
Can I get tides and a marine forecast for my own spot near Jacksonville Beach?
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 Jacksonville Beach today?
