Where this tide comes from
Yi O Pier has no station of its own, so we use the tide at Macau (TICON-4), 20 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.

The moon in Yi O Pier
Moon phase and position
Today the moon is 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:29–3:29 am Major · the moon passes overhead · high activity
- 2:02–4:02 pm Major · the moon passes underfoot · high activity
- 9:06–10:06 am Minor · moonset · medium activity
- 7:57–8:57 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.
