Tidal currents near Cohasset Harbor (White Head)
From NOAA's current predictions for Weir River entrance at 10 ft depth, 5.2 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 ENE (76°) and the ebb toward the W (272°). The strongest current this week is 0.9 knots.

Best fishing times at Cohasset Harbor (White Head)
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 Cohasset Harbor (White Head)
Cohasset Harbor (White Head) 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 8.3 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 11.6 ft, and again around Sunday, October 11 (10.1 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Monday, October 19, with only 6.6 ft between the day's highest and lowest water.
The lowest tide of the month is -1.0 ft at 6:47 PM on Tuesday, October 27. There are 12 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 10.7 ft at 1:12 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.
