Where this tide comes from
Icatu has no station of its own, so we use the tide at Ponta da Madeira (São Luís, TICON-4), 26 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- 1:29–3:29 am Major · the moon passes overhead · high activity

- 8:09–9:09 am 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.
