San Juan, La Puntilla, San Juan Bay, PR Daily Water Report — August 25, 2026

Today is a prime day for diving in San Juan Bay, with a stellar score of 9/10. The calm seas and warm waters, currently at 29°C, create near-perfect conditions beneath the surface. Boaters will also find favorable conditions with an 8/10 score, thanks to gentle winds averaging 3 knots from the SSE and minimal wave heights around 0.58m at their calmest. Fishing, however, might require a bit of patience, scoring 6.3/10. The solunar tables suggest the best chance for a catch is during the major period from 5:06 to 7:06 AM. Tidal movements are subtle today, with a low of 0.06m at 12:25 PM, which might not stir up the waters enough for a feeding frenzy. Surfers and sailors might be less enthused, with scores of 5.6/10 and 5/10, respectively. The swell is modest at 0.54m from 55 degrees, and the wind is not consistent enough to provide the push sailors might desire. Kayakers will enjoy a 7.2/10 day, with manageable wind waves and a gentle ocean current moving at 0.8 m/s toward 315 degrees. Comparing to recent days, diving and kayaking have seen a slight boost, while fishing has dipped from an 8.2/10 just two days ago. The weather remains stable, with no rain expected until after noon, keeping visibility clear at 20 km. Looking ahead, the upcoming days will see a slight uptick in wave activity, with potential rain increasing from mid-week. For a memorable outing, take advantage of today's calm waters and dive into the vibrant marine life San Juan Bay offers before the winds pick up later in the afternoon.
