Where Oceanographic Institution is
Oceanographic Institution sits at 41.5236° N, 70.6711° W on the southern New England coast, at Woods Hole, MA. The station here is a live gauge in NOAA's National Water Level Observation Network, the reference network the rest of the coast's tide predictions are tied to. It has been in NOAA's records since 1932. The nearest weather station is Woods Hole, MA, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Oceanographic Institution
Oceanographic Institution 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 2.0 high tides a day here. The mean range from lower low to higher high is 2.2 ft, and 1.8 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.1 ft below the other low. For the water around it: Tides along Narragansett Bay, Buzzards Bay and the islands are semidiurnal but vary sharply over short distances, from 1 ft on Nantucket Sound to 4 ft in Narragansett Bay.
About this station
- High tide reaches Oceanographic Institution about 0.7 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: 10.8 ft on Sep 21, 1938.
- Lowest on record: -3.3 ft on Feb 2, 1976.
- The National Weather Service counts 5.5 ft as minor flooding here, 7.0 ft as moderate and 8.5 ft as major.
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 Oceanographic Institution from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 2.2 ft above it and mean sea level 1.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 1.4 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. Source: NOAA CO-OPS station 8447930, a National Water Level Observation Network gauge, established 1932. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Oceanographic Institution this month: Nov 9, Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Oceanographic Institution this month: Nov 22, Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28, Nov 29, Nov 30. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for Oceanographic Institution, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
