Mona Island, PR Daily Water Report — October 7, 2026

Mona Island is a good day for sail-powered plans and a worthwhile day for fishing or diving, but it is not a casual small-craft day. Sailing leads the board at 8.4/10, with fishing and diving both at 8.1. Boating sits at 5.7 and kayaking at 4.9, reflecting the meaningful tradeoff: warm water and generally favorable timing, but a persistent ESE breeze, choppy short-period seas, and stronger afternoon gusts. The most workable water window is early, before the wind builds toward its 26.8-knot peak gust around 2 PM. Waves are forecast at 1.2 to 1.7 m through the day, with the calmest reading near midnight at 1.24 m; the representative sea is 1.32 m at a compact 5.95 seconds. That is enough motion to make exposed runs and paddle returns more demanding than the headline wave height alone suggests. The 1.12 m swell from 140 degrees is joined by 0.48 m wind waves, while current is running about 0.36 m/s toward the east. For anglers, the 9:04-11:04 AM solunar major period is the cleanest daylight timing, arriving around the morning low at 9:02 AM. A second major period runs 9:04-11:04 PM, after sunset. Pressure is rising near 1014 hPa, and the fishing score is notably stronger than the 5.6 posted on October 1. For divers, 30 C surface water and low chlorophyll support the strong model score, though neither metric guarantees underwater visibility; surface wind and short-period seas still deserve respect at entries and exits. Expect a humid, mostly cloudy day with light precipitation possible at any hour. Atmospheric visibility is forecast near 41.6 km, but that is a sky-and-horizon measure, not a read on the water below. The evening high tide reaches only 0.26 m at 6:17 PM, so tidal range remains modest. Compared with recent reports, today is breezier than September 27 and carries weaker boating and kayaking scores, while diving remains close to the better recent days. Seas ease to roughly 1.0-1.3 m from Thursday through Monday, though rain chances stay elevated before dropping by October 13. Best bet: launch early, fish the 9 AM major window or dive only within your proven limits, and be off the exposed water before the afternoon gusts start throwing their weight around.
