We had 50° at the Caissons yesterday. Today we decided to dive shallower, so we hit the wreck of the Avalon and the Redondo Barge. The water at the Avalon was green and also 50° with a pretty hefty current running. The water over the barge was full of chunks in the brown surface water. After twenty feet the brown water turned to green, and finally cleared up around sixty feet. The clear water on the bottom was 49°. I can't wait for December so I can warm up.

Are those more octopus eggs?
 
There is a new nest on a brick where we have found eggs the past three years. I think they like that spot. We've found eggs in six separate months so far.
 
Max - Laguna Sea Sports was reporting 70 at the surface last week (as high as 73 on Sat 6/1 - though that may be an exaggeration). How is it that PV can be that cold and just 30 ish miles south be so warm? Not second guessing you, I'm just curious to learn from someone more experienced in this area?

Is this perhaps a byproduct of the large swells we currently had this past weekend, which they said originated from New Zealand?
 
The water off O.C., known as Huntington Flats is relatively shallow for a few miles offshore. Newport Canyon comes close to shore, but currents take the cold upwellings away from Laguna Beach. Palos Verdes is surrounded by very deep water from Redondo Canyon and the San Pedro Escarpment. It is common to have water temperatures in fifty feet at Marineland in the low fifties at the same time as temps in the upper sixties in Laguna Beach.
 
...How is it that PV can be that cold and just 30 ish miles south be so warm?

Go to a map of California....find Point Conception and Point Vicente (PV)...draw a straight line...and you'll see how the current comes down California...that's water from Alaska,,,,

It's why there are so many differrent kinds of nudibranchs there....they love that cold current.
 
We've had an influx of cold water out at Casino Point too. My last dive there (several weeks ago) had a bottom temp of 64 F but I've been getting reports of temps in the 52-54 F range at comparable depths recently. Surface temps have been 66-72 F according to reports. I'm still a warm water wussy after three weeks in the Philippines so I'm sticking close to my video editing computer!
