La Jolla, CA Daily Water Report — October 4, 2026

La Jolla gets a strong all-around water day, with diving and boating leading the card and a notably gentle sea state doing most of the heavy lifting. The 0.7–0.8 m wave range, long 12-second pulse, nearly absent wind chop, and light southerly winds make this a clean-looking setup on paper for the activities scored here. That is not a safety guarantee—conditions can still vary sharply by launch, exposure, and timing—but the broad marine picture is unusually cooperative. The best practical window is early, from dawn through midmorning, before the day’s strongest gusts arrive around 9 AM. Winds remain light overall, though gusts could reach 13.8 knots then, enough to make small craft and surface intervals less relaxed than the representative 5-knot reading suggests. The sea is calmest near 1 AM at 0.72 m, but daylight users should find little change through the morning. Water is warm at 23.6 C, about 2.9 C above average, supporting the day’s 9.4/10 diving score alongside low waves and light wind. Atmospheric visibility is forecast at 27.4 km under clear skies; useful for navigation and horizon checks, but not a claim about underwater visibility. Boating rates 8.7/10 and kayaking 7.8/10, with minimal precipitation risk, light current around 0.17 m/s toward 236 degrees, and modest seas. Sailing earns 7/10: pleasant water, but not much breeze for anyone hoping the sails will do all the work. Fishing is a middling-to-good 6.7/10, with the morning solunar major period from 6:48 to 8:48 AM and another from 6:48 to 8:48 PM providing the more favorable timing. The afternoon high tide reaches 1.58 m at 4:41 PM; the relatively small morning low of 0.95 m arrives at 10:45 AM. Compared with the reconstructed recent scores, diving holds steady at its excellent 9.4, boating is just a shade below yesterday, and fishing improves from yesterday’s 6.3. Wildlife’s 6.6 is softer than the last few days. The next two days stay light-wind and dry, but seas begin building Tuesday and continue upward through the week. Best bet: make Sunday morning your water-time appointment—warm water, low seas, and just enough breeze to keep the ocean honest.
