↓ Falling The tide is falling. 5 h 58 min to low tide at 7:29 am.
Tide coefficient 85 for the 12:33 am high tide and 82 for the 1:21 pm high tide. Average coefficient. The water rises and falls 0.4 ft between the highest high and the lowest low: a small 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 27 (0.5 ft) and the lowest, on June 15 (-0.3 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 89, 0.5 ft range). The smallest, from October 18 to 19 (coefficient 40, -0.1 ft).

Where this tide comes from
Tides from the Sebastian station (NOAA), 0.6 mi from Sebastian. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Government Cut reference station with the official corrections.

The sea at Sebastian
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.2 ft
- Significant6.5 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
Onshore wind. The coast faces east and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 6.5 ft with a period of 9 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 78.7 °F by Wednesday 4.
Water colder than normal for late October (−1.5 °F).

Surf in Sebastian today
Surf today
Fair- 4.0–6.2 ft surf at the shore, a good size with some punch
- 5.2 ft swell at 8 s from the east-northeast, a bit short
- Light onshore wind (8 mph): a bit of chop
- First or last light of the day
- Rising tide (high tide at 1:21 pm)
Rip current risk today: high (statement in effect) (NWS)
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: 5.0–6.0 ft
- Light: First light 7:07 am · sunrise 7:31 am · sunset 6:40 pm · last light 7:04 pm
- Tide: high 12:33 am (0.5 ft), low 7:29 am (0.0 ft), high 1:21 pm (0.5 ft) and low 8:01 pm (0.3 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 77.2 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 355 kJ · Medium power
Today’s surf at a glance
The best window, 7:07 am to 11:00 am, has a good size. 3:00 pm to 5:00 pm can also work, with a good size, though with a short-period swell.
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 Sebastian today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (1:21 pm): little current from 12:00 pm to 2:50 pm
- 4.9 ft swell at 7 s from the northeast: strong surge on the bottom
- Light onshore wind (9 mph)
- 0.4 mph current toward the south-southeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 12:33 am (11:10 pm–2:00 am), low tide 7:29 am (6:00–8:50 am), high tide 1:21 pm (12:00–2:50 pm) and low tide 8:01 pm (6:40–9:30 pm)
- Likely visibility: poor. Swell (up to 6.8 ft at 9 s) and rain (2.58 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 77.2 °F: a 3 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:04 pm. Waning gibbous (84%), rising at 9:44 pm: a bright night.
Your diving day at a glance
The best window, 1:30 pm to 4:30 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 5:30 pm to 6:30 pm, with light wind and weak current, though with some swell.
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.

Moon phase and position
Today the moon is 226,746 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 3:02–5:02 am Major · the moon passes overhead · high activity
- 3:34–5:34 pm Major · the moon passes underfoot · high activity
- 10:54–11:54 am Minor · moonset · medium activity
- 9:14–10:14 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. Very shallow: the water doesn't reach 16 ft within 2.3 mi. Cast far from the beach, ideally around high tide.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 2.3 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 2.3 mi out.
