La Jolla Visibility Today: C Grade on a Big Tide Swing

Saturday in La Jolla is a mid pack C. Our beta model has Saturday at C grade, 10 to 14 feet, medium confidence. That is the published number. Diveable. Not glass. If you showed up hoping for twenty feet of canyon blue, lower the bar before you zip up.

The swell load is the quiet part of the card. Surf sits around 3.5 feet. The main swell is a short west swell near 2.2 feet at about 7 seconds, with a 1.6 foot west southwest swell at about 12.5 seconds underneath it. Short period energy is what kicks sand around in the shallows, and that west swell is still the thing keeping this from a cleaner B. The model puts a B around 18 percent and a D around 16 percent, so a miss could go either way.

The story today is the tide. The published range is about 6.2 feet. High sits near 6 feet around 7 a.m., then the water dumps to a slightly negative low around 2 p.m. That is a lot of water moving across the reef for a Saturday. Expect more pull and more nearshore stir than you got midweek. Best window from the model is still early to late morning, before the breeze wakes up.

Wind is the afternoon spoiler. The forecast averages about 7 mph, but it climbs toward 11 or 12 by noon, with gusts near 16. Same play as the rest of this stretch: get wet early. Once the surface gets textured, the C does not get prettier.

The water is still warm for November. The buoy in the published file is reading about 76 degrees. Bring whatever rubber that number usually means for you. One buoy reading is not a full-column thermometer.

Water quality still matters more than the letter on some days. County data last pulled Friday still shows the advisory at the end of Marine Street, plus the long running flags at La Jolla Cove and Children's Pool. Tourmaline Drain Outlet is flagged too. Most of the Shores stretch is open. If Marine Street or the Cove was the plan, check the county map and think about a Shores entry instead.

Camera check: the newest Scripps Pier snapshot is still Friday's 4 p.m. slot. Saturday's daylight captures have not landed yet, so that image is yesterday's look, not this morning's. The grader also failed on that frame, which only means we do not get an auto vis grade from the cam. The picture itself is still up.

Bottom line: a Saturday built on a C, a big tide, and a morning clock. Go early, start clean, keep your expectations around a dozen feet, and be happily surprised if the canyon edge is clearer. Full numbers are on the La Jolla forecast page.

Our vis model is in beta and still being validated, so treat the grade as odds, not a promise.
