Tidal currents near Sea Otter Harbor
From NOAA's current predictions for Millar Rocks, 6.0 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 NNE (30°) and the ebb toward the SSW (210°). The strongest current this week is 1.9 knots.

Best fishing times at Sea Otter Harbor
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.

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 Sea Otter Harbor
Sea Otter Harbor 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 7.4 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 13.9 ft, and again around Monday, November 9 (11.9 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Monday, October 19, with only 5.1 ft between the day's highest and lowest water.
The lowest tide of the month is -2.0 ft at 8:36 PM on Tuesday, October 27. There are 15 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 11.9 ft at 1:40 PM on Tuesday, October 27. 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.
