About Sarasota & Siesta Key

The forecast point for Sarasota & Siesta Key represents conditions near Siesta Key, while exposed water, beaches, wetlands, courses, or remote access within the coverage area may differ. The day’s key decisions involve beach or coastal wind, lightning, fairway saturation, tee-time heat, and bridge access.

Planning an Outing at Sarasota & Siesta Key

Check beach or coastal wind, lightning, fairway saturation, tee-time heat, and bridge access for the exact access point and activity—not just the nearest city forecast. Confirm current park, refuge, marina, ramp, ferry, road, bridge, course, or operator notices that apply to Sarasota & Siesta Key, and preserve enough daylight and shelter margin to change plans.

Weather Tips for Sarasota & Siesta Key

  • Check wind, tides, marine forecasts, beach flags or inlet current, and water-quality notices for the exact access area.
  • Leave beaches, boats, piers, open golf courses, and exposed shorelines immediately when thunder is heard.
  • During tropical threats, follow local evacuation, bridge, marina, ferry, campground, and coastal-closure instructions; storm surge may affect access before landfall.
  • Check conditions near St. Armands shortly before the activity starts.
  • Use sun protection, hydration, insect protection, and a reliable lightning shelter.
