Today along the San Luis Obispo County coast, NOAA shows patchy morning fog, then light WNW winds around 5 to 10 knots with mixed swell holding near 3 feet at the forecast point 8 nautical miles south-southwest of San Luis Obispo. Nearby marine guidance also indicates WNW swell around 2 feet at 8 seconds with a south-southwest swell around 2 feet at 17 seconds, which supports a modest average wave size near 3 feet.

For the local tide picture at Port San Luis, NOAA tide predictions list a high tide at 6:28 PM near 5.27 feet, with the next low tide having occurred at 11:37 AM near 1.68 feet. Earlier tides included a low at 12:49 AM near 1.17 feet and a high at 6:25 AM near 3.07 feet.

The marine pattern remains fairly steady tonight, with NW winds around 5 to 10 knots and continuing fog at times after dark. Swell stays mixed, with WNW energy near 2 feet at 8 seconds and SSW energy near 2 feet at 16 seconds, so surf should stay small to moderate with a soft, wind-affected feel.

Overall, today favors light to moderate conditions near shore, with the best structure coming from the northwest and a secondary south-southwest ground swell. Wave sizes should average around 3 feet, with a few sets a bit larger in the more exposed spots.
