Where Magens Bay, St. Thomas is
Magens Bay, St. Thomas sits at 18.3663° N, 64.9221° W on the northeastern Caribbean, about 1 mi northeast of Charlotte Amalie, VI, in Saint Thomas. 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 Charlotte Amalie, ST. Thomas Island (NOAA 9751639), 2.5 mi away, and high and low water here run on average about 5 min earlier than there. The nearest weather station is Charlotte Amalie, VI, a shore station reporting wind and, at most sites, water temperature, 2.2 mi away.
The tide at Magens Bay, St. Thomas
Magens Bay, St. Thomas has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains a little lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 1.3 ft, and 0.9 ft between the average high and the average low, a small 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 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.
About this station
- High tide reaches Magens Bay, St. Thomas about 0.4 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 Magens Bay, St. Thomas from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.3 ft above it and mean sea level 0.6 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 San Juan, La Puntilla, San Juan Bay, PR gauge. Source: NOAA CO-OPS station 9751693, 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.
