Where this tide comes from
Chembényoumba has no station of its own, so we use the tide at Longoni (REFMAR (Shom)), 6.7 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.
Station data attribution: REFMAR, LONGONI (Shom), http://dx.doi.org/10.17183/REFMAR#6263, https://data.shom.fr/donnees/refmar/6263: sea level observations of 2025-10-28 to 2026-10-01.

The sea at Chembényoumba
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.5 ft
- Highest expectedHighest3.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.1 ft. Before heading out, expect waves of up to 3.1 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces west and the wind comes off the land at an angle: calmer water near the shore, and bait and boats 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: 2.4 ft with a period of 7 s, from the southwest (slight).
Water temperature
Water temperature →The satellite measured 4.5 °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 (+3.7 °F).

Surf in Chembényoumba 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 west-southwest, short: weak, messy waves
- Moderate offshore wind (14 mph): it holds up and grooms the waves
- Falling tide (low tide at 12:00 pm)
- Light: First light 5:06 am · sunrise 5:28 am · sunset 5:59 pm · last light 6:21 pm
- Tide: high 5:39 am (12.6 ft), low 12:00 pm (1.4 ft), high 5:59 pm (10.5 ft) and low 11:58 pm (1.9 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 86.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 5 kJ · Low power
Today’s surf at a glance
The best window, 5:06 am to 9:00 am, has light offshore wind, though with small waves and 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.
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, 11:30 am to 12:50 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 5:10 pm to 6:00 pm, with slack water at high tide, little swell, light wind and weak current.
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 226,576 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:17–3:17 am Major · the moon passes overhead · high activity
- 1:49–3:49 pm Major · the moon passes underfoot · high activity
- 7:34–8:34 am Minor · moonset · medium activity
- 9:05–10:05 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. 33 ft of water just 750 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 750 ft and 66 ft at 1,100 ft from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
