San Juan, La Puntilla, San Juan Bay, PR Daily Water Report — August 24, 2026

Today in San Juan Bay, the conditions are tailor-made for divers and anglers, with diving scoring a robust 8.9/10 and fishing at 8.2/10. The calmest waters are expected around 4 AM, with wave heights at a gentle 0.52 meters. Divers will appreciate the stable barometric pressure and the inviting sea surface temperature of 29.1°C, coupled with clear oligotrophic waters. Anglers, take note of the prime solunar periods just before dawn and late in the afternoon, aligning beautifully with the tide cycles for optimal fishing. Boaters and sailors will find the conditions moderately favorable, scoring 6/10 and 8.2/10 respectively. The east-northeast winds are blowing at a steady 15 knots, gusting to 20, which may add a bit of spice to your sails but could be a bit challenging for less experienced kayakers, who face a lower suitability score of 5.3/10. The winds are forecasted to be strongest around 10 AM, so plan accordingly. Surfers might find the day less than ideal, with a score of 6/10. While the wave height is manageable at around 0.66 meters, the short period of 4.55 seconds and the wind direction might not deliver those long, clean rides. Comparing to recent days, today's conditions are a mix of highs and lows, with diving and fishing showing improvement over the past two days while boating has dipped from an 8.6/10 just yesterday. Looking ahead, the coming days bring increasing chances of precipitation, peaking at 80% tomorrow. Wave heights are expected to gradually increase, reaching up to 1.1 meters by the 29th, which could improve surfing conditions but may challenge other activities. For today, if you're looking for that sweet spot, diving in the morning hours before the winds pick up is your best bet for an unforgettable underwater experience.
