Big tides in Pleubian
L'essentiel
Big tides (coefficient ≥ 90) in Pleubian, on the Wild Peninsula (Côtes-d'Armor), are referenced to Port-Béni (SHOM). The Talbert Spit is partially submerged at high coefficients. These tides offer the best shore-fishing windows and the most spectacular coastal scenery.

Understanding coefficients
The tide coefficient (scale 20 to 120, calculated by the SHOM) characterises the tidal range: below 45 is a neap tide (low range); 45–70 is an average tide; 70–90 is spring tide; above 90 is a big tide. Equinoctial tides (coefficients ≥ 100, around March and September) are the most spectacular of the year.

Safety tips
- · Never venture onto the Talbert Spit on a rising tide — the shingle spit is partially submerged and the retreat can be cut off.
- · Always check the tide time before leaving (SHOM, maree.shom.fr) and keep a constant eye on the sea.
- · Never go shore fishing alone — inform someone of your location and fishing schedule.
- · Bring a charged mobile phone to stay reachable.
- · Respect restricted areas (prefectural orders) and the sanitary quality of sites (ARS Bretagne).
Shore fishing
Périodes
The best periods are during spring tides (coefficient ≥ 70), about one hour before low tide. Days with coefficient ≥ 90 offer the largest exposed seabed areas.
Zones
Around Pleubian, the coves of Port-la-Chaîne and Port-Béni are the most practicable zones. Kermagen beach is suitable for beginners.
Matériel
Basic gear: landing net, buckets, shellfish knife, non-slip shoes, measuring gauge (available at tourist offices).
Réglementation
Respect minimum sizes and quotas set by prefectural order. Harvest only adult specimens. Do not collect in seagrass beds. Sort your catch as you go and leave behind what you won't keep.

What is the tide coefficient?
The tide coefficient is a number (20 to 120) that characterises the tidal range, calculated by the SHOM. Below 45 is a neap tide; 45–70 is an average tide; 70–90 is spring tide; above 90 is a spring tide (grande marée). The higher the coefficient, the higher the sea rises and the further it retreats.
When are the big tides in Pleubian?
Big tides (coefficient ≥ 90) occur about every 15 days, around full and new moons. The most spectacular ones occur near the equinoxes (March and September). In 2026, the highest coefficients are expected on 19–22 March (coeff. 104), 17–20 April (coeff. 105), 13–15 August (coeff. 102) and 11–13 September (coeff. 102).
Can you go shore fishing in Pleubian?
Yes, shore fishing is practicable around Pleubian, especially in the coves of Port-la-Chaîne and Port-Béni. The best periods are during spring tides (coefficient ≥ 70), about one hour before low tide. Respect minimum sizes, quotas and restricted areas (prefectural orders). Check the sanitary quality of sites on the ARS Bretagne website.
Is the Talbert Spit dangerous during big tides?
The Talbert Spit is partially submerged during big tides: the sea can cover the shingle spit and cut off the retreat. Never venture onto the spit on a rising tide. Check the tide time before leaving and keep a constant eye on the sea. The return may be impossible if the tide rises during the visit.
Where to watch tides in Pleubian?
The best viewpoints are the Talbert Spit (spectacular submersion), the coves of Port-la-Chaîne and Port-Béni (visible tidal range), and Kermagen beach. The reference port is Port-Béni (SHOM data). Precise times are available on the SHOM website (maree.shom.fr).
What is the tidal range in Pleubian?
At Port-Béni (reference port), the tidal range varies from about 3 m at neap tide to over 7 m at spring tide. At coefficients ≥ 100, the sea can rise 7.5 to 8 m above the chart datum.
Do you need a permit for shore fishing?
Recreational shore fishing is free for shellfish and crustaceans, within quotas and minimum sizes set by prefectural order. Line fishing for fish is regulated. Check the pecheapied-responsable.fr website and local orders from the Côtes-d'Armor prefecture.
