The sea at Binic
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.5 ft
- Significant1.0 ft
- Highest expectedHighest2.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.1 ft. Before heading out, expect waves of up to 2.1 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northeast 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 build over the next few days. The biggest waves arrive on Tuesday 3: 4.5 ft with a period of 5 s, from the northeast (moderate).
Water temperature
Water temperature →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 56.8 °F by Wednesday 4.

The best window, 7:20 am to 11:00 am, has light offshore wind, though with barely any 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.

Your diving day at a glance
The best window, 2:30 pm to 4:00 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 8:00 am to 9:20 am, with slack water at high tide, little swell, light wind and weak 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.

Solunar periods
Today's activity: medium- 2:37–4:37 am Major · the moon passes overhead · high activity

- 11:55 am–12:55 pm Minor · moonset · 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 1.6 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.
Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
