Your diving day at a glance
The best window, 5:10 pm to 6:30 pm, combines slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 12:10 pm to 12:50 pm, with slack water at low tide and the sun high, though with some swell, moderate wind and 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.

Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:31–4:31 am Major · the moon passes overhead · high activity
- 3:03–5:03 pm Major · the moon passes underfoot · high activity
- 11:34 am–12:34 pm Minor · moonset · medium activity
- 7:31–8:31 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 1.8 mi out for 33 ft of water.
From the shoreline (2.1 mi from Rivedoux-Plage) out to sea, heading southwest.
How far from shore
- 16 ft deep1.1 mi
- 33 ft deep1.8 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 1.1 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 1.8 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.
