Shark's Cove isn't quite living up to its crystal-clear summer reputation today, leaning more towards a fair than fantastic day. The 1-2 ft surf combined with a steady 14.8 mph ENE cross-shore wind means a bit of chop and a less-than-ideal lava rock entry. The estimated visibility today is 20-30 ft, which is decent, but not the epic clarity we see on truly flat days here.
