Where this tide comes from
Octeville has no station of its own, so we use the tide at Cherbourg (TICON-4), 1.8 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at Octeville
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.5 ft
- Highest expectedHighest3.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.0 ft. Before heading out, expect waves of up to 3.0 ft.
Wind on the coast and offshore
Offshore wind. The coast faces north and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Tuesday 3: 2.2 ft with a period of 4 s, from the northeast (slight).
Water temperature

Surf in Octeville today
Surf today
Poor- 0.7–1.0 ft surf at the shore, small: good for learning or a longboard
- 1.1 ft swell at 8 s from the west, a bit short; it hits this coast at an angle
- Light offshore wind (5 mph): it holds up and grooms the waves
- First or last light of the day
- Rising tide (high tide at 10:21 am)
- Light: First light 7:17 am · sunrise 7:50 am · sunset 5:50 pm · last light 6:23 pm
- Tide: low 5:00 am (3.5 ft), high 10:21 am (20.7 ft), low 5:27 pm (3.4 ft) and high 10:48 pm (19.9 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 60.6 °F: a 4/3 fullsuit.
- Energy: 15 kJ · Low power
Today’s surf at a glance
The best window, 7:17 am to 11:00 am, has light offshore wind, though with small waves.
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.

Diving in Octeville today

Likely visibility: good- Some tidal current
- 0.9 ft swell at 8 s from the west: barely any surge
- Light offshore wind (6 mph)
- 0.1 mph current toward the north, weak (model)

- Likely visibility: good. Swell (up to 2.2 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 60.6 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: good, calm sea and light wind.
- Night dive: dark from 6:23 pm. Waning gibbous (85%), rising at 7:42 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 12:20 pm, combines 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.

Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:32–4:32 am Major · the moon passes overhead · high activity
- 3:04–5:04 pm Major · the moon passes underfoot · high activity
- 11:56 am–12:56 pm Minor · moonset · medium activity
- 7:12–8:12 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 quicklyThe bottom deepens quickly: 33 ft of water 850 ft from shore.
From the shoreline (2.4 mi from Octeville) out to sea, heading north.
How far from shore
- 16 ft deep260 ft
- 33 ft deep850 ft
- 66 ft deep2.3 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 20 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. 33 ft deep 850 ft from shore; 66 ft is far out (2.3 mi): for deeper dives, go by boat.
Right by the shore the bottom may drop even faster than shown.
