Slack is when the current turns and the water is calmest; flood runs in with the rising tide and ebb runs out with the falling tide. Times are the peak of each run, in knots. The flood runs toward the N (4°) and the ebb toward the WNW (291°). The strongest current this week is 0.3 knots.

Best fishing times at Bay of Isles, South Arm
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 Bay of Isles, South Arm
Bay of Isles, South Arm 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 9.3 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 17.0 ft, and again around Sunday, November 8 (14.7 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Monday, October 19, with only 6.1 ft between the day's highest and lowest water.
The lowest tide of the month is -2.3 ft at 9:03 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 14.7 ft at 2:17 PM on Tuesday, October 27. 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.
