Where Boston Light is
Boston Light sits at 42.3283° N, 70.8917° W on the Gulf of Maine, at Hull, MA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2000 until 2004, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Boston (NOAA 8443970), 8.3 mi away, and the tide here runs on nearly the same clock. The nearest weather station is Castle Island (NOS) 8444069, a shore station reporting wind and, at most sites, water temperature, 6.2 mi away.
The tide at Boston Light
Boston Light 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 9.8 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 Boston Light 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: 11.8 ft on Feb 21, 2004.
- Lowest on record: -2.8 ft on Feb 12, 2001.
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 Boston Light from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 9.8 ft above it and mean sea level 4.9 ft. These datums are controlled from NOAA's Boston, MA gauge. Source: NOAA CO-OPS station 8444162, established 2000, gauge removed 2004. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
