La Jolla conditions
La Jolla visibility today, Oct 31: a C from Wednesday night
Ten to fourteen feet, and the run is three days old.
Stand on the sand at the Cove and the green closes in a few kicks out. You can make out the near reef. The far rocks disappear. That's a C. Dive Pro's beta model calls La Jolla a C for Saturday, Oct 31, 10 to 14 feet, with medium confidence.
The grade is three days old. It comes from the last model run, Wednesday night, Oct 28. No new run has been posted since.
C is the most likely outcome, about 39%, and that is a lean, not a lock. B still has about 29%. A B would be 15 to 24 feet, enough that the structure past the first drop shows up. F is about 18%, water you turn around in. D is about 15%, where the near rocks go soft.
The best window is early to late morning, before the wind builds. After that the surface chops up and the little viz goes with it.
The ocean feels warm on your ankles. NOAA station 46254, the Scripps nearshore buoy, read 75.6 F at 6:26 AM PT. Yesterday's post said 73.9. It came up.
It's Halloween. The date does not clear the water.
From the lot the sets look small and far apart. That buoy had waves about 1.6 feet at 14 seconds, out of the west-northwest. A gap of 14 seconds gives the wave time to reach the bottom and tug the kelp.
Overnight the rocks barely uncovered. NOAA's La Jolla tide station had a high of 3.4 feet at 3:39 AM and a low of 3.1 feet at 6:43 AM, barely a low, so the reef stays covered. It fills to 5.4 feet at 1:16 PM, then falls to minus 0.1 feet at 9:22 PM. The big drop is after lunch into night. That falling water drags sand through the entry.
On that Wednesday run, Sunday, Nov 1, looks bumpier on paper and comes up a B, 15 to 24 feet, medium confidence. Its inputs show a bigger, short-period wind swell, about 5 seconds, around 4.5 feet, and rain that can cloud the nearshore. About 5 seconds means the waves are stacked tight. They slap the surface and stir the bottom. Rain puts dirt in that water. A B from a three-day-old run with rain in it is not a lock.
On Thursday, Oct 29, San Diego County posted new advisories at La Jolla Shores (Del Oro) and at Marine Street. La Jolla Cove and Children's Pool were under advisories as of Thursday too. Check the County list before you get in.
Last good frame on the Scripps pier camera was Wednesday, Oct 28, around 4:13 PM. Nothing has come in after it, so no camera backs up the grade.
The Dive Pro model is beta and hasn't been validated yet. Treat the grade as odds, not a promise.
