Any Boating or Snorkeling event happened today? (Jul 30)

I live on the beach in LBTS (north of Anglin Pier) and normally I see like 1-3 boats max at a time. Today the entire ocean was full like 20-30 just in my field of view and most or all had dive flags.

Just wondering what the event was. The weather didn't seem much different than most days.
