Chilly Key Largo Morning Tantalizing Snorkeling Scuba Fun. Here in Key Largo this morning we woke to see 62F air temperature. That cool North breeze didn’t stop our morning fun. Captain Dave headed out to Elbow Reef with Deeper and our boat full of excited snorkeling and scuba guests. Inst. Holly taught classroom PADI Scuba tune-up and Discover Scuba Diving to the morning class. They are headed to the pool and then will join our afternoon boat tour. Inside the dive shop, sales of our snuggly Sail Fish Scuba logo hoodie sweatshirts, are the hit of the day.
