Where this tide comes from
Tides from the Larmor-Baden station (REFMAR (Golfe du Morbihan ‑ Vannes Agglomération)), 0.4 mi from Larmor-Baden. Times and heights are its predictions.

The sea at Larmor-Baden
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.6 ft
- Highest expectedHighest3.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.3 ft. Before heading out, expect waves of up to 3.3 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces south 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 Thursday 29: 2.0 ft with a period of 9 s, from the west-southwest (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 54.9 °F by Wednesday 4.

Your diving day at a glance
The best window, 12:50 pm to 2:20 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 7:50 am to 8:40 am, with 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Larmor-Baden
Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:37–4:37 am Major · the moon passes overhead · high activity
- 3:10–5:10 pm Major · the moon passes underfoot · high activity
- 11:49 am–12:49 pm Minor · moonset · medium activity
- 7:30–8:30 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
Shallow, gradualShallow, gradual bottom: you need to go 1.3 mi out for 33 ft of water.
From the shoreline (0.4 mi from Larmor-Baden) out to sea, heading southwest.
How far from shore
- 16 ft deep0.8 mi
- 33 ft deep1.3 mi
- 66 ft deep2.2 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.8 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 near shore: you only reach 33 ft at 1.3 mi. For dives deeper than 33 ft, go by boat.
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.
