  • ▲ High tide 9:00 pm 10.4 ft · coef. 81

↓ Falling The tide is falling. 1 h 4 min to low tide at 2:28 am.

Tide coefficient 83 for the 8:34 am high tide and 81 for the 9:00 pm high tide. Average coefficient. The water rises and falls 9.5 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 December 26 (11.8 ft) and the lowest, on August 14 (0.6 ft).

Semidiurnal: two high and two low tides a day, of similar height.

Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Tide coefficient and range in October

The biggest tides of the month came from October 9 to 10 (coefficient 91, 10.0 ft range). The smallest, on October 20 (coefficient 42, 4.8 ft).

Your diving day at a glance

The best window, 7:50 am to 9:20 am, combines slack water at high tide, little swell, light wind and weak current. Also worth a look from 2:20 pm to 3:20 pm, with slack water at low tide, little swell, weak current and the sun high, though with moderate wind. Also worth a look from 10:20 am to 12:30 pm, with little swell, light wind, weak current and the sun high, though with tidal 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods

Today's activity: medium
  • 2:37–4:37 am Major · the moon passes overhead · high activity
  • 3:09–5:09 pm Major · the moon passes underfoot · high activity
  • 11:49 am–12:49 pm Minor · moonset · medium activity
  • 7:29–8:29 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.

Water depth

Very shallow

Very shallow and flat: 3.1 mi from shore the water is still only about 3 ft deep.

From the shoreline (1.4 mi from Séné) out to sea, heading south.

How far from shore

  • 16 ft deep1.5 mi
  • 33 ft deepnot within 3.1 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 1.5 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.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. The profile is turned slightly from the coast so it does not run into an island or a headland. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
