Where Great Chebeague Island is
Great Chebeague Island sits at 43.7217° N, 70.1417° W on the Gulf of Maine, about 2 mi south of Cousins Island, ME. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Portland (NOAA 8418150), 6.7 mi away, and the tide here runs on nearly the same clock. The nearest weather station is Portland, ME, a shore station reporting wind and, at most sites, water temperature, 6.9 mi away.
The tide at Great Chebeague Island
Great Chebeague Island 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 9.9 ft, and 9.1 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 0.3 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 Great Chebeague Island about 3.6 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from Portland, station 8418150. High tide comes about 2 min later and low tide about 2 min later than there.
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 Great Chebeague Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 9.9 ft above it and mean sea level 4.9 ft. These datums are controlled from NOAA's Portland, ME gauge. Source: NOAA CO-OPS station 8417881, established 1979, gauge removed 1979. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
