La Jolla visibility today, Oct 25: a C, and get in early

Sunday at the Cove looks like a C. The Dive Pro beta model, updated early this morning, has La Jolla at 10 to 14 feet of visibility. It gives a C about a 54 percent chance and a B about 29 percent. So there's a real shot it's better than that. There's also a 16 percent D hanging around in the corner.

Here's what's in the water. The main swell is about 2 feet from the SSW at 12 seconds. That's a long-period south swell, the kind with some push behind it, but 2 feet of it isn't much. Under that is a smaller WNW bump, about 1.3 feet at 8 seconds. Surf runs around 3 feet, a little smaller than the last few days, which sat closer to 3.6 to 3.9.

The morning is the whole story. Wind is basically nothing early, under 2 mph at 7 and 8am. By 1pm it's 9 mph, and it tops out around 12 mph at 3pm. Wind is what puts chop on top and stirs up the shallows.

Then the tide. High tide is around 8:43am at about 6 feet. After that it drains hard, all the way to a minus tide around 3:27pm. That's a swing of more than 6 feet. A falling tide pulls the murky water off the beach and the reef and out toward you. A rising tide tends to bring cleaner water in from offshore. Today the clean push happens before breakfast.

So put it together. Calm wind and a high tide at the same time, roughly 8 to 10am. That's your window. By the afternoon you get wind on top and a minus tide dragging sand off the bottom. Not a disaster. Just worse.

One more thing. As of Saturday morning, the County had a general rain advisory up for every La Jolla station, issued Thursday after the rain. The model only saw about three hundredths of an inch over the last three days, so this wasn't a big storm. But advisories are about runoff, not inches. Check sdbeachinfo.com before you put your face in it.

The model is beta. It's still in testing and hasn't been validated, so treat it like odds, not a promise. If you go, tell us what you actually saw.
