Where Riverside is
Riverside sits at 42.7639° N, 71.0340° W on the Gulf of Maine, at Haverhill, MA, in Essex County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1989 until 1989, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Seavey Island (NOAA 8419870), 26.4 mi away, and high and low water here run on average about 140 min later than there. The nearest weather station is Lawrence Municipal Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 5.8 mi away.
The tide at Riverside
Riverside 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 6.3 ft, and 5.7 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.5 ft and the lower low sits 0.1 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 Riverside about 5.5 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
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 Riverside from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.3 ft above it and mean sea level 2.8 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. These datums are controlled from NOAA's Newburyport, Merrimack River, Ma gauge. Source: NOAA CO-OPS station 8440889, established 1989, gauge removed 1989. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Riverside this month: Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28, Nov 29. 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 Riverside this month: Nov 1, Nov 6, Nov 7, Nov 8, Nov 9, Nov 10, Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28 …. 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 Riverside, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
