Where this tide comes from
La Roche-Derrien has no station of its own, so we use the tide at Saint-Quay-Portrieux (TICON-4), 21 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.

Solunar periods
Today's activity: medium- 2:39–4:39 am Major · the moon passes overhead · high activity
- 3:11–5:11 pm Major · the moon passes underfoot · high activity
- 11:58 am–12:58 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.
