Where this tide comes from

B · Nearby station

Quemper-Guézennec has no station of its own, so we use the tide at Saint-Quay-Portrieux (TICON-4), 14 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.

Sea and waves

The sea at Quemper-Guézennec

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · gentle breeze, Beaufort 3
Waves 1.0 ft · 8.4 s from the west-northwest (300°)

The waves you may find

  • Most commonMost common0.5 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

Offshore (21 mi NNE)Offshore 11 mph SE · gusts 15

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.

Your diving day at a glance

The best window, 7:50 am to 8:30 am, combines slack water at high tide, little swell, light wind and weak current. Also worth a look from 2:30 pm to 3:30 pm, with slack water at low tide, little swell, light wind and the sun high, though with 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods

Today's activity: medium
  • 2:38–4:38 am Major · the moon passes overhead · high activity
  • 3:11–5:11 pm Major · the moon passes underfoot · high activity
  • 11:57 am–12:57 pm Minor · moonset · medium activity
  • 7:24–8:24 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.
