Where Southwest Point, Block Island is
Southwest Point, Block Island sits at 41.1633° N, 71.6100° W on the southern New England coast, about 13 mi south of Quonochontaug, RI, in Washington County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1998 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 Montauk, Fort Pond Bay (NOAA 8510560), 19.9 mi away, and high and low water here run on average about 86 min earlier than there. The nearest weather station is Block Island State Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 1.7 mi away.
The tide at Southwest Point, Block Island
Southwest Point, Block 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 3.0 ft, and 2.6 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.2 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 Southwest Point, Block Island about 0.3 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 Southwest Point, Block Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.0 ft above it and mean sea level 1.4 ft. These datums are controlled from NOAA's Newport, RI gauge. Source: NOAA CO-OPS station 8459681, established 1998, 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.
