Today's high and low tides
- ▼ Low tide 3:36 am -0.2 ft
- ▲ High tide 10:08 am 6.8 ft · coef. 85
- ▼ Low tide 4:31 pm 0.2 ft
- ▲ Next high tide 10:27 pm 5.3 ft · coef. 83
↑ Rising The tide is rising. 1 h 45 min to high tide at 10:27 pm.
Tide coefficient 85 for the 10:08 am high tide and 83 for the 10:27 pm high tide. Average coefficient. The water rises and falls 7.0 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on October 28 (6.8 ft) and the lowest, on June 15 (-1.0 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 26 to 28 (coefficient 85, 7.0 ft range). The smallest, from October 17 to 19 (coefficient 46, 3.8 ft).

Where this tide comes from
Tides from the Jacksonville Beach station (NOAA), 0.9 mi from Jacksonville Beach. Times and heights are its predictions.

The sea at Jacksonville Beach
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.1 ft
- Significant6.2 ft
- Highest expectedHighest13 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 6.6 ft with a period of 8 s, from the east-northeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 72.3 °F by Tuesday 3.
Water colder than normal for late October (−3.7 °F).

Surf in Jacksonville Beach today
Surf today
Poor- 4.2–6.5 ft surf at the shore, a good size with some punch
- 5.4 ft swell at 8 s from the east, short: weak, messy waves
- Fresh cross-shore wind (20 mph): a bit of chop
- Falling tide (low tide at 4:31 pm)
Rip current risk today: high · tomorrow: high (NWS, statement in effect)
Stay out of the water: rip currents can pull even strong swimmers out to sea. If one catches you, don't swim against it: swim parallel to the shore and wave for help.
Surf height from the NWS, today: 7.0–9.0 ft
- Light: First light 7:12 am · sunrise 7:37 am · sunset 6:41 pm · last light 7:06 pm
- Tide: low 3:36 am (-0.2 ft), high 10:08 am (6.8 ft), low 4:31 pm (0.2 ft) and high 10:27 pm (5.3 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 70.7 °F: a springsuit or a 2 mm fullsuit.
- Energy: 352 kJ · Medium power
Today’s surf at a glance
The best window, 3:00 pm to 5:00 pm, has a good size, though with a short-period swell and cross-shore wind. 7:12 am to 8:00 am can also work, with a good size, though with a short-period swell and onshore wind.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Diving in Jacksonville Beach today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (10:08 am): little current from 9:50 am to 10:30 am
- 5.5 ft swell at 8 s from the east: strong surge on the bottom
- Fresh onshore wind (22 mph)
- 0.5 mph current toward the south-southeast, weak (model)
- Daylight
- Slack water today: low tide 3:36 am (3:10–4:00 am), high tide 10:08 am (9:50–10:30 am), low tide 4:31 pm (4:00–5:00 pm) and high tide 10:27 pm (10:00–10:50 pm)
- Likely visibility: poor. Swell (up to 5.5 ft at 8 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 70.7 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:06 pm. Waning gibbous (91%), rising at 8:37 pm: a bright night.
Your diving day at a glance
The best window, 9:20 am to 10:30 am, combines slack water at high tide and weak current, though with some swell and fresh wind. Also worth a look from 3:30 pm to 5:20 pm, with slack water at low tide and weak current, though with some swell and fresh wind.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:01–4:01 am Major · the moon passes overhead · high activity
- 2:33–4:33 pm Major · the moon passes underfoot · high activity
- 9:57–10:57 am Minor · moonset · medium activity
- 8:07–9:07 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. About 7.2 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. 33 ft deep 0.55 mi from shore; 66 ft is far out (beyond 3.1 mi): for deeper dives, go by boat.
