Port San Luis, CA Daily Water Report — August 25, 2026

Today's the day to grab your board or your dive gear and head to Port San Luis. Both surfing and diving are scoring a solid 8.3/10, making the most of the favorable conditions. The waves are rolling in at around 1.06 meters with a period of 9.75 seconds, perfectly timed for those who know how to ride them. The swell is coming from the southwest, which should give surfers some nice rides, particularly with the light winds from the north keeping the surface smooth for much of the day. Divers, you'll appreciate the stable barometric pressure and the relatively calm seas. The sea surface temperature is a bit warmer than usual, at 16.9°C, thanks to a +2.7°C anomaly, which might make your underwater exploration a bit more comfortable. Just be aware of the ocean current moving at 0.3 meters per second toward the northwest, which could influence your dive plan. Fishing is looking up with a score of 7.8/10, an improvement over previous days. The solunar periods around mid-morning and late evening should be your prime windows. Boaters and kayakers will find today quite accommodating as well, with scores of 7.6 and 7.7 respectively. The wind is gentle for most of the day, but it picks up in the late afternoon, so plan your adventures accordingly. Sailing, however, is less ideal today with a score of 4.6/10, primarily due to inconsistent wind speeds. For wildlife enthusiasts, the conditions are decent with a score of 7.3/10, so keep an eye out for local fauna during the solunar periods. Looking ahead, the next few days will see increasing wave heights, peaking on the 29th, so surfers should prepare for some thrilling conditions. For today, catch the best waves and dive into the clear waters just after the morning high tide at 10:10 AM.
