Best fishing times at Apia (Observatory), Upolu Island
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.

Heights are in feet above mean lower low water (MLLW), the zero line on most US nautical charts. A minus height means the water drops below that line.
About the tides at Apia (Observatory), Upolu Island
Apia (Observatory), Upolu Island gets two high tides and two low tides almost every day, and the two highs are close in height. Over the next month the water typically rises or falls about 2.5 ft between a high and the next low.
The biggest swings in this window come around Monday, October 26, when the day's range reaches 3.5 ft, and again around Friday, November 6 (3.0 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Friday, October 16, with only 1.7 ft between the day's highest and lowest water.
The lowest tide of the month is 3.8 ft at 12:36 AM on Monday, October 26.
The highest predicted tide is 7.3 ft at 6:54 PM on Monday, October 26. Onshore wind or a storm can push the real water level above that.
This is a reference (harmonic) station: NOAA predicts its tides directly from years of measured water levels here, which makes it among the most reliable predictions on the coast.
