Where Mona Island is
Mona Island sits at 18.0893° N, 67.9382° W on the northeastern Caribbean, about 48 mi west of Rincón, PR, in Mayaguez. The station here is a live gauge in NOAA's National Water Level Observation Network, the reference network the rest of the coast's tide predictions are tied to. It has been in NOAA's records since 2006. The nearest weather station is Mona Island, PR, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Mona Island
Mona 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 0.8 ft, and 0.7 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 Mona Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.8 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 9759938, a National Water Level Observation Network gauge, established 2006. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
