Where this tide comes from
Tides from the Honfleur station (REFMAR (HAROPA PORT – Rouen)), 2.6 mi from Équemauville. Times and heights are its predictions.
Station data attribution: REFMAR, HONFLEUR_HAROPA_RO (HAROPA PORT – Rouen), http://dx.doi.org/10.17183/REFMAR#385, https://data.shom.fr/donnees/refmar/385: sea level observations of 2025-09-30 to 2026-10-01.

The sea at Équemauville
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.1 ft
- Highest expectedHighest2.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.3 ft. Before heading out, expect waves of up to 2.3 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 3.1 ft with a period of 5 s, from the west-northwest (slight).
Water temperature
Water temperature →The satellite measured 4.1 °F more yesterday than the model gives now: the water is probably warmer than the forecast says.
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 55.7 °F by Tuesday 3.
Water colder than normal for late October (−1.1 °F).

Surf in Équemauville today
Surf today
Poor- 1.5–2.3 ft surf at the shore, a fun size for most surfers
- 2.1 ft swell at 4 s from the west-northwest, short: weak, messy waves
- Light cross-shore wind (8 mph): a bit of chop
- First or last light of the day
- Rising tide (high tide at 10:30 am)
- Light: First light 7:08 am · sunrise 7:41 am · sunset 5:44 pm · last light 6:18 pm
- Tide: low 7:14 am (4.5 ft), high 10:30 am (27.8 ft), low 7:36 pm (4.5 ft) and high 10:51 pm (27.4 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 56.8 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 13 kJ · Low power
Today’s surf at a glance
The best window is 7:08 am to 11:00 am, though with a short-period swell.
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.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in Équemauville today
Diving and snorkeling today
Likely visibility: good- 1.5 ft swell at 4 s from the west-northwest: barely any surge
- Light onshore wind (9 mph)
- 0.2 mph current toward the south-southwest, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 7:14 am (6:59–7:29 am), high tide 10:30 am (10:15–10:45 am), low tide 7:36 pm (7:20–7:51 pm) and high tide 10:51 pm (10:36–11:06 pm)
- Likely visibility: good. Swell (up to 2.8 ft at 5 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 56.8 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:18 pm. Waning gibbous (93%), rising at 6:39 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 1:30 pm, combines little swell, light wind, weak current and the sun high.
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 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:21–3:21 am Major · the moon passes overhead · high activity
- 1:52–3:52 pm Major · the moon passes underfoot · high activity
- 10:31–11:31 am Minor · moonset · medium activity
- 6:09–7:09 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.

- 66 ft deepnot within 3.1 mi

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.1 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
The profile is turned slightly from the coast so it does not run into an island or a headland.
