    Best fishing times at Grand Bay

    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.

    About the tides at Grand Bay

    Grand Bay gets usually just one high tide and one low tide a day. Over the next month the water typically rises or falls about 1.2 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 2.2 ft, and again around Tuesday, November 10 (1.7 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 0.3 ft between the day's highest and lowest water.

    The lowest tide of the month is -0.4 ft at 12:40 PM on Thursday, October 29. 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 1.8 ft at 1:53 AM on Friday, October 30. 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.
