Best fishing times at Chiachi Island (east side)
Solunar periods for this spot: major periods (about two hours) are centred on the moon passing overhead or underfoot, and minor periods (about an hour) on moonrise and moonset. Days near the new and full moon rate higher, and so does a period that lines up with sunrise, sunset or a turn of the tide.

Solunar times are a rule of thumb many anglers use, not a guarantee. Moving water around a tide change usually matters as much.

About the tides at Chiachi Island (east side)
Chiachi Island (east side) gets two high tides and two low tides most days, but one high is clearly higher than the other (and one low clearly lower), which is called a mixed tide. Over the next month the water typically rises or falls about 5.3 ft between a high and the next low.
The biggest swings in this window come around Tuesday, October 27, when the day's range reaches 11.7 ft, and again around Monday, November 9 (9.8 ft). Here the biggest ranges depend on the moon's phase and on how far north or south of the equator it is, so they don't always line up with the new and full moon. The calmest day is Monday, October 19, with only 3.4 ft between the day's highest and lowest water.
The lowest tide of the month is -2.1 ft at 10:18 PM on Tuesday, October 27. There are 14 minus tides (lows below the chart's zero line) in this window: the best times for tide pools, clamming and walking the flats.
The highest predicted tide is 9.6 ft at 3:58 PM on Wednesday, October 28. Onshore wind or a storm can push the real water level above that.
This is a subordinate station: NOAA calculates its times and heights by adjusting a nearby reference station, so expect them to be a few minutes or a few tenths of a foot off on any given day.
