Tidal currents near Unalga Bight
From NOAA's current predictions for Adak Strait, off Argonne Point, 6.3 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 N (10°) and the ebb toward the SSW (200°). The strongest current this week is 3.2 knots.

Best fishing times at Unalga Bight
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.

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 Unalga Bight
Unalga Bight gets usually just one high tide and one low tide a day. 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 Friday, October 30, when the day's range reaches 5.6 ft, and again around Tuesday, November 10 (4.6 ft). Here the biggest ranges depend on the moon's phase and on how far north or south of the equator it is, so they don't always line up with the new and full moon. The calmest day is Friday, October 23, with only 1.6 ft between the day's highest and lowest water.
The lowest tide of the month is -1.3 ft at 2:55 AM on Friday, October 30. There are 17 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 4.4 ft at 5:02 PM on Thursday, October 29. 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.
