Where Johns Folly Bay, St. John Island is

Johns Folly Bay, St. John Island sits at 18.3170° N, 64.7021° W on the northeastern Caribbean, about 1 mi southeast of Coral Bay, VI. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2020 until 2021, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Lameshur Bay, St. Johns Island (NOAA 9751381), 1.5 mi away, and high and low water here run on average about 14 min earlier than there. The nearest weather station is Lameshur Bay, St John, VI, a shore station reporting wind and, at most sites, water temperature, 1.4 mi away.

The tide at Johns Folly Bay, St. John Island

Johns Folly Bay, St. John Island has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.2 high tides a day here. The mean range from lower low to higher high is 0.9 ft, and 0.8 ft between the average high and the average low, a small tide. For the water around it: Tides around Puerto Rico and the Virgin Islands are small, about a foot, and lean diurnal, so one high and one low a day is common.

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 Johns Folly Bay, St. John Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.9 ft above it and mean sea level 0.4 ft. The land survey datum VIVD09, the zero on topographic maps and flood maps, is 0.6 ft above MLLW here, so a water level on this page converts to VIVD09 by subtracting that amount. These datums are controlled from NOAA's Lameshur Bay, St John, VI gauge. Source: NOAA CO-OPS station 9751274, established 2020, gauge removed 2021. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
