Best fishing times at South Yarmouth, Bass River
The bite score (0 to 100) adds up what anglers watch most: moving water (a tide running harder than usual here scores higher), solunar periods (major periods of about two hours centred on the moon overhead or underfoot, minor periods of about an hour on moonrise and moonset), dawn and dusk light, and how close it is to the new or full moon. Best times are the stretches of the day scoring near that day's top.

About the tides at South Yarmouth, Bass River
South Yarmouth, Bass River 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 2.6 ft between a high and the next low.
The biggest swings in this window come around Wednesday, October 28, when the day's range reaches 3.7 ft, and again around Sunday, October 11 (3.2 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Monday, October 19, with only 2.1 ft between the day's highest and lowest water.
The lowest tide of the month is -0.3 ft at 8:35 PM on Tuesday, October 27. There are 11 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 3.4 ft at 2:56 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.
