Where Las Mareas is

Las Mareas sits at 17.9283° N, 66.1583° W on the northeastern Caribbean, about 2 mi south of Jobos, PR. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2001 until 2002, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is San Juan (NOAA 9755371), 36.8 mi away, and high and low water here run on average about 20 min later than there. The nearest weather station is Jobos Bay Weather, Jobos Bay Reserve, PR, a shore station reporting wind and, at most sites, water temperature, 4.7 mi away.

The tide at Las Mareas

Las Mareas 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 1.1 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 Las Mareas from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.7 ft above it and mean sea level 0.3 ft. These datums are controlled from NOAA's Magueyes Island, PR gauge. Source: NOAA CO-OPS station 9755679, established 2001, gauge removed 2002. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
