Where this tide comes from
Tides from the Port-Launay station (REFMAR (Vigicrues)), 1.2 mi from Châteaulin. Times and heights are its predictions.

The sea at Châteaulin
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.4 ft
- Significant2.9 ft
- Highest expectedHighest5.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.7 ft. Before heading out, expect waves of up to 5.7 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces north 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 Thursday 29: 3.2 ft with a period of 10 s, from the west-southwest (slight).

Your diving day at a glance
The best window, 12:00 pm to 3:00 pm, combines slack water at low 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.

Solunar periods
Today's activity: medium- 2:42–4:42 am Major · the moon passes overhead · high activity
- 3:15–5:15 pm Major · the moon passes underfoot · high activity
- 11:58 am–12:58 pm Minor · moonset · medium activity
- 7:31–8:31 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.
