San Juan, La Puntilla, San Juan Bay, PR Daily Water Report — September 3, 2026

Today in San Juan Bay, the waters are inviting, especially for divers and boaters who will find near-perfect conditions. With a diving score of 9/10, visibility is expected to be excellent, aided by calm winds and minimal wave action. Boaters will also enjoy an 8.2/10 score, thanks to the gentle 2-knot winds from the south, which create a smooth ride across the bay. Kayakers will find their sweet spot early in the day when wave heights are at their calmest around 0.42 meters near 5:00 AM. As the day progresses, expect the winds to pick up, reaching a gusty peak of 21.4 knots by 5:00 PM, which might add some excitement for the more adventurous paddlers. Surfers might find today a bit underwhelming with a score of 4.9/10. The wave height maxes out at 0.7 meters, and the short, choppy periods of 3.75 seconds won’t provide much of a ride. Comparatively, just a few days ago, surfing conditions were more favorable with scores peaking at 7.6/10. Fishing enthusiasts should plan their outings around the solunar major periods from 4:16 to 6:16 AM and 4:16 to 6:16 PM. The fishing score of 6.7/10 suggests a decent day, though slightly down from the previous days. Looking ahead, the weather turns a bit wetter with a 43% chance of rain tomorrow, increasing to 80% by September 5th. Winds will remain moderate, and wave heights will slightly increase, providing potentially better conditions for surfers later in the week. For today, if you’re seeking the best aquatic adventure, diving is your top bet. Dive deep and enjoy the crystal-clear waters before the winds pick up.
