Where Guanica is
Guanica sits at 17.9580° N, 66.9068° W on the northeastern Caribbean, at Guánica, PR. 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 Magueyes Island (NOAA 9759110), 9.2 mi away, and high and low water here run on average about 28 min earlier than there. The nearest weather station is Magueyes Islands, PR, a shore station reporting wind and, at most sites, water temperature, 9.2 mi away.
The tide at Guanica
Guanica 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 1.0 high tides a day here. The mean range from lower low to higher high is 0.7 ft, 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 Guanica from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.7 ft above it and mean sea level 0.4 ft. The land survey datum PRVD02, the zero on topographic maps and flood maps, is 0.4 ft above MLLW here, so a water level on this page converts to PRVD02 by subtracting that amount. These datums are controlled from NOAA's Magueyes Island, PR gauge. Source: NOAA CO-OPS station 9758627, 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.
