Check EventsIt depends on the UV index and your skin. Our conditions page converts today's hourly UV forecast at Marathon into minutes to burn using the standard erythemal dose model, so instead of "UV 9" you get "unprotected fair skin burns in about 18 minutes", along with the strongest stretch of the day and when to reapply. Open sand and water reflect UV back at you, so the estimate includes a beach uplift.
Check Today's Burn TimeIt depends on when. Dogs are welcome at all City of Marathon parks and beaches, leashed, with owners picking up waste. The only exception is the Community Park soccer and baseball fields.
