↓ Falling The tide is falling. 5 h 4 min to low tide at 11:56 am.
Tide coefficient 98 for the 5:01 am high tide and 94 for the 6:36 pm high tide. Spring tides. The water rises and falls 13.6 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 April 19 (6.1 ft) and the lowest, on December 26 (-9.0 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level
Tide coefficient and range in October
The biggest tides of the month came from October 27 to 29 (coefficient 100, 13.7 ft range). The smallest, from October 19 to 20 (coefficient 31, 5.0 ft).

Where this tide comes from
Sematan has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.3 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.
Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.
The sea at Sematan
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest2.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.9 ft. Before heading out, expect waves of up to 2.9 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Saturday 31: 2.1 ft with a period of 8 s, from the north-northeast (slight).
Water temperature
Water temperature →The satellite measured 4.0 °F less 2 days ago than the model gives now: the water is probably colder than the forecast says.
Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.
Water warmer than normal for late October (+3.0 °F).

Surf in Sematan today
Surf today
Poor- 0.9–1.3 ft surf at the shore, small: good for learning or a longboard
- 0.9 ft swell at 6 s from the north, short: weak, messy waves
- Almost no wind (2 mph): glassy water
- Thunderstorm: stay out of the water (lightning)
- Rising tide (high tide at 6:36 pm)
Thunderstorms in the best window: with lightning, stay out of the water.
- Light: First light 6:02 am · sunrise 6:23 am · sunset 6:26 pm · last light 6:48 pm
- Tide: high 5:01 am (4.8 ft), low 11:56 am (-8.0 ft) and high 6:36 pm (5.6 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 88.7 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 5 kJ · Low power
Today’s surf at a glance
The best window, 2:00 pm to 6:00 pm, has glassy water, though with small waves, a short-period swell and thunderstorms.
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.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance
The best window, 11:10 am to 12:40 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high.
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 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:47–3:47 am Major · the moon passes overhead · high activity
- 2:19–4:19 pm Major · the moon passes underfoot · high activity
- 8:36–9:36 am Minor · moonset · medium activity
- 9:02–10:02 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. Shallow, gradual bottom (16 ft at 1.4 mi): cast far from the beach and fish the high tide, when there is more water close in.
- 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 3.1 mi. For deeper dives, take a boat farther out.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
