Where Walpole is
Walpole sits at 43.9333° N, 69.5800° W on the Gulf of Maine, about 5 mi north of Boothbay Harbor, ME. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1976 until 1981, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Portland (NOAA 8418150), 38.2 mi away, and high and low water here run on average about 6 min later than there. The nearest weather station is Wiscasset Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 6.8 mi away.
The tide at Walpole
Walpole has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 10.2 ft, and 9.3 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.4 ft and the lower low sits 0.4 ft below the other low. For the water around it: Gulf of Maine tides are semidiurnal and large, 9 ft at Boston rising past 18 ft toward the Bay of Fundy.
About this station
- High tide reaches Walpole about 3.7 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 13.4 ft on Jan 28, 1979.
- Lowest on record: -2.2 ft on Dec 31, 1978.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Walpole from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 10.2 ft above it and mean sea level 5.1 ft. These datums are controlled from NOAA's Portland, ME gauge. Source: NOAA CO-OPS station 8416731, established 1976, gauge removed 1981. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
