Where this tide comes from
Cayeux-sur-Mer has no station of its own, so we use the tide at Dieppe (TICON-4), 25 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 Cayeux-sur-Mer
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.4 ft
- Significant2.7 ft
- Highest expectedHighest5.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.5 ft. Before heading out, expect waves of up to 5.5 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northwest 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 Monday 2: 3.9 ft with a period of 5 s, from the north (slight).
Water temperature
Water temperature →The satellite measured 2.7 °F more 2 days ago 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 is steady these days, with no sudden changes.
Water about normal for late October.

Surf in Cayeux-sur-Mer today
Surf today
Fair- 2.2–3.4 ft surf at the shore, a fun size for most surfers
- 2.8 ft swell at 8 s from the west, short: weak, messy waves
- Light offshore wind (6 mph): it holds up and grooms the waves
- Rising tide (high tide at 1:24 pm)
- Light: First light 7:05 am · sunrise 7:39 am · sunset 5:36 pm · last light 6:10 pm
- Tide: high 1:06 am (31.1 ft), low 8:05 am (4.5 ft), high 1:24 pm (31.0 ft) and low 8:29 pm (4.4 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 57.2 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 82 kJ · Low power
Today’s surf at a glance
The best window, 8:00 am to 12:00 pm, has a good size and light offshore wind, though with a short-period swell. 5:00 pm to 6:00 pm can also work, with a good size and light offshore wind, 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.

Your diving day at a glance
The best window, 1:00 pm to 2:10 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.

Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:19–4:19 am Major · the moon passes overhead · high activity

- 11:47 am–12:47 pm Minor · moonset · medium activity
- 6:55–7:55 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 1.8 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.
