Even during the dog days of summer, when the common wisdom says Floridians retreat indoors to the comfort of their air conditioners, beaches and other attractions in and around Sarasota are bustling. Siesta Key Beach was named the best beach in America in 2011 by “Dr. Beach,” a professor at a Florida university and arbiter of such rankings. Siesta’s baby-powder sands are easy on the feet even on the hottest days. For those turned off by the relentless sunshine and mid-90s heat, shops and restaurants on the main street of the quaint St. Armands or the famed Ringling Museum just off downtown Sarasota are fine places to chill out. And with such major league attractions in the area as the Tampa Rays baseball team and professional football and hockey teams, and the large Tampa International Airport nearby, Sarasota is a magnet for retirees seeking fun and sun.
