We visited the Manatee viewing area in Apollo Beach, FL the last week in December. There were some manatee spotted about two hundred yards from the boardwalk. The weather was still warm then, in the 70’s.
With the national cold snap, bringing snow to northern Florida and the ocean water in the mid 50’s we went to another manatee area in Homosassa at the Florida State Park. Here we were able to see dozens of manatee relatively close in crystal clear water. The spring in Homosassa runs about 73 degrees; creating a nice warm environment for the fish and manatee. We some an excursion boat with people in wet suits attempting to swim with the Manatee.
