The waves you may find
- Most commonMost common2.2 ft

- Likely visibility: poor. Swell (up to 8.1 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 57.7 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:37 pm. Waning gibbous (85%), rising at 8:04 pm: a bright night.
Your diving day at a glance
The best window, 11:40 am to 1:30 pm, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 5:20 pm to 6:00 pm, with light wind and weak current, though with some swell.
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- 2:44–4:44 am Major · the moon passes overhead · high activity
- 3:16–5:16 pm Major · the moon passes underfoot · high activity
- 11:59 am–12:59 pm Minor · moonset · medium activity
- 7:34–8:34 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
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 380 ft from shore.
From the shoreline (1.5 mi from Beuzec-Cap-Sizun) out to sea, heading northwest.
How far from shore
- 16 ft deep280 ft
- 33 ft deep380 ft
- 66 ft deep950 ft
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 24 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. Shore diving works here: 33 ft at 380 ft and 66 ft at 950 ft from shore.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. Right by the shore the bottom may drop even faster than shown.
