Where Arecibo is
Arecibo sits at 18.4805° N, 66.7024° W on the northeastern Caribbean, at Arecibo, PR. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2007 until 2024, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Mayaguez (NOAA 9759394), 35.2 mi away, and high and low water here run on average about 23 min earlier than there. The nearest weather station is Arecibo, Puerto Rico (249), an offshore buoy reporting wind, waves and water temperature, 0.7 mi away.
The tide at Arecibo
Arecibo 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 1.8 ft, and 1.2 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.2 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 Arecibo about 0.1 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 2.7 ft on Oct 8, 2010.
- Lowest on record: -0.8 ft on Apr 27, 2009.
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 Arecibo from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.8 ft above it and mean sea level 0.8 ft. These datums are controlled from NOAA's San Juan, La Puntilla, San Juan Bay, PR gauge. Source: NOAA CO-OPS station 9757809, established 2007, gauge removed 2024. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
