Sunday out of San Carlos beach was actually pretty good. More surge - but since I rarely notice anything other than extreme surge - not bad. Students were out in force and having a good time. I took a 90 min u/w swim from the stair in the corner to Metridiums and back. Lots to see with at least 5 different types of fish in large schools, crabs galore, even more Sea Hares, a few California Sea Slugs. Viz not bad at 20' or so (see the pic below to get a sense). Very warm. 59F at the surface 57F at 50'
