Use clear windows, not a fixed schedule.
Check live radar and the posted beach flag before swimming, keep an indoor lunch or Village stop ready and leave the water at the first sound of thunder. If skies improve later, regroup for a relaxed sunset rather than rushing the afternoon.
Move between the beach and dry stops without the parking shuffle.
Call Siesta Free Ride when the weather changes. We can connect the beach, Village, restaurants and your hotel while your group stays flexible.
Check live radar, posted beach flags and lifeguard guidance before entering the water. Conditions can change quickly, especially during Florida's summer storm season.
