Best fishing times at Cape Mordvinof
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 Cape Mordvinof
Cape Mordvinof 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 4.1 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 8.5 ft, and again around Tuesday, November 10 (7.1 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Thursday, October 22, with only 3.7 ft between the day's highest and lowest water.
The lowest tide of the month is -1.7 ft at 4:20 AM on Friday, October 30. There are 18 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 6.9 ft at 1:14 PM on Saturday, October 31. 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.
