The sea at Le Havre
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest2.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.9 ft. Before heading out, expect waves of up to 2.9 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 3.8 ft with a period of 5 s, from the west-northwest (slight).
Water temperature
Water temperature →The satellite measured 2.9 °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 57.1 °F by Tuesday 3.
Water about normal for late October.

Surf in Le Havre today
Surf today
Poor- 1.7–2.6 ft surf at the shore, a fun size for most surfers
- 2.5 ft swell at 4 s from the west-northwest, short: weak, messy waves
- Light onshore wind (9 mph): a bit of chop
- First or last light of the day
- Rising tide (high tide at 11:02 am)
- Light: First light 7:08 am · sunrise 7:41 am · sunset 5:45 pm · last light 6:18 pm
- Tide: low 6:28 am (4.0 ft), high 11:02 am (26.9 ft), low 6:52 pm (3.8 ft) and high 11:23 pm (26.5 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 58.3 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 20 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.

Diving in Le Havre today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (11:02 am): little current from 10:47 am to 11:40 am

- Light onshore wind (9 mph)
- 0.2 mph current toward the southwest, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 10:44 pm (10:29 pm–12:10 am), low tide 6:28 am (5:50–6:50 am), high tide 11:02 am (10:47–11:40 am), low tide 6:52 pm (6:20–7:10 pm) and high tide 11:23 pm (11:08 pm–12:50 am)
- Likely visibility: good. Swell (up to 3.2 ft at 5 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 58.3 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:18 pm. Waning gibbous (93%), rising at 6:38 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 1:40 pm, combines slack water at high tide, 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
- 1:53–3:53 pm Major · the moon passes underfoot · high activity
- 10:32–11:32 am Minor · moonset · medium activity
- 6:08–7:08 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 1.2 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 2 mi. For dives deeper than 33 ft, go by boat.
