Tidal currents near Southwest Point, Block Island
From NOAA's current predictions for Lewis Pt., 1.5 miles west of, 1.5 miles away. 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 NW (318°) and the ebb toward the S (170°). The strongest current this week is 2.0 knots.

Best fishing times at Southwest Point, Block 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.

About the tides at Southwest Point, Block Island
Southwest Point, Block 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 2.6 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 4.0 ft, and again around Sunday, October 11 (3.5 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Sunday, October 18, with only 1.5 ft between the day's highest and lowest water.
The lowest tide of the month is -0.3 ft at 2:14 AM on Tuesday, October 27. There are 9 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 3.7 ft at 8:54 AM 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.
