Culebra, PR Daily Water Report — October 8, 2026

Culebra is a good sailing-and-diving day, but only a fair-to-middling one for small craft that dislike an easterly breeze. Sailing leads the board at 8.7/10 and diving follows at 8.5/10; boating is 6.3, fishing 6.5, kayaking 5.9, and wildlife 5.8. Those are suitability guides, not safety clearances. The water is holding near 1.0 m all day, with the calmest forecast around midnight at 0.94 m. Most of that energy is a short 4.8-second sea, including 0.52 m wind waves, plus 0.84 m of swell from 113 degrees. That is manageable rather than glassy, and the 14-knot easterly—gusting to 18 knots, with a 20-knot gust forecast near 7:00 AM—will make exposed water feel busier than the headline wave height suggests. The current is forecast toward 342 degrees at about 0.17 m/s, another small but real factor for paddlers, divers, and anyone timing a return. For fishing, the stronger daylight opportunity is the 9:39–11:39 AM solunar major period, with the low tide arriving at 12:55 PM. A second major period runs 9:39–11:39 PM. Pressure is rising from a relatively low 1012.5 hPa toward 1015.9 hPa, while the early rain window is confined to midnight through 6:00 AM. Cloud cover is heavy at 96%, so do not confuse the forecast 18.9 km atmospheric visibility with underwater visibility. Diving gets warm 29.6 C water, modest seas, and the day’s best activity score, though surface chop and wind remain the tradeoff. That score is essentially unchanged from yesterday’s 8.4. Fishing has slipped from yesterday’s 7.7, while boating is also a touch lower than yesterday’s 6.7. Sailing, meanwhile, remains reliably strong and slightly improves on yesterday’s 8.6. The next few days keep waves near 0.9–1.2 m through Saturday, with rain chances rising sharply Friday and Saturday. Conditions look more settled by Monday and Tuesday, when waves are forecast near 0.8 m and winds ease toward 12 knots. Best bet: rig the sail or plan a dive with an early wind check, then let the late-morning solunar window do the rest.
