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

How we calculate the tide

Sea and waves

The sea at Saint-Georges-de-Didonne

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · gentle breeze, Beaufort 3
Waves 4.0 ft · 12.5 s from the west-northwest (282°)

The waves you may find

  • Most commonMost common2.0 ft

  • Highest expectedHighest7.9 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.9 ft. Before heading out, expect waves of up to 7.9 ft.

Wind on the coast and offshore

On the coast 7 mph NE · gusts 13
Offshore (7.3 mi S)Offshore 9 mph NE · gusts 14

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.

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.

Your diving day at a glance

The best window, 11:30 am to 12:30 pm, combines slack water at low tide, light wind and the sun high, though with some swell and current. Also worth a look from 4:50 pm to 6:00 pm, with slack water at high tide, light wind and weak current, though with some swell.

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: high
  • 1:26–3:26 am Major · the moon passes overhead · high activity
  • 1:57–3:57 pm Major · the moon passes underfoot · high activity
  • 10:16–11:16 am Minor · moonset · medium activity
  • 6:34–7:34 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

Deepens quickly

The bottom deepens quickly: 33 ft of water 0.25 mi from shore.

From the shoreline (0.65 mi from Saint-Georges-de-Didonne) out to sea, heading west.

How far from shore

  • 16 ft deep1,200 ft
  • 33 ft deep0.25 mi
  • 66 ft deep1.4 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. 33 ft of water just 0.25 mi 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. 33 ft deep 0.25 mi from shore; 66 ft is far out (1.4 mi): for deeper dives, go by boat.
