San Juan, La Puntilla, San Juan Bay, PR Daily Water Report — August 31, 2026

Today's a mixed bag for water enthusiasts around San Juan Bay. Divers, this is your day to shine with an impressive 8.7/10 suitability score. The calmest waters are expected near 11 PM, with wave heights dropping to 0.76 meters, making for excellent underwater conditions. The water temperature is a toasty 29.5°C, and visibility should be decent given the low chlorophyll levels, indicating clear blue waters. Surfers will find decent conditions with a 7.6/10 score. The waves are peaking at 1.4 meters, and the swell coming from 54 degrees should make for some lively action, especially during the early afternoon when the wind is at its strongest. However, the gusts reaching up to 16.3 knots might be a bit challenging. For those looking to fish, the 6.9/10 score suggests it's a fair day. The solunar tables indicate the best times for fishing are between 1:36-3:36 AM and 1:36-3:36 PM. With the barometric pressure rising, it might just give that extra edge for a good catch. Boaters and kayakers should be cautious as the suitability scores are on the lower side, 5.7/10 and 5/10 respectively. The combination of moderate winds and the ocean current moving at 1.5 m/s could make for a bumpy ride. Plus, there's a chance of rain until 8 PM, so keep an eye on the skies. Looking ahead, expect a wetter week with high chances of rain and slightly calmer seas. By September 3rd, the wind is forecasted to ramp up again, which could impact conditions further. In a nutshell, divers and surfers can seize the day, while others might want to keep a weather eye out. If diving's your thing, tonight's clear, warm waters are calling your name.
