Where Castle Hill is
Castle Hill sits at 41.4633° N, 71.3617° W on the southern New England coast, at Newport, RI, in Newport County. 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 Newport (NOAA 8452660), 3.4 mi away, and high and low water here run on average about 4 min later than there. The nearest weather station is Newport, RI, a shore station reporting wind and, at most sites, water temperature, 3.4 mi away.
The tide at Castle Hill
Castle Hill 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 3.6 ft, and 3.2 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 Castle Hill about 0.2 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 Newport, station 8452660. High tide comes about 5 min earlier and low tide about 13 min later than there.
- High tide heights run about 0.94 times the reference.
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 Castle Hill from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.6 ft above it and mean sea level 1.6 ft. These datums are controlled from NOAA's Newport, RI gauge. Source: NOAA CO-OPS station 8453201, established 1977, gauge removed 1977. 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.
