Quick answers
What is the water temperature in Perdido Key today?

Is the water clear in Perdido Key?
Perdido Key is known for clear, emerald-green Gulf water over sugar-white sand, but clarity isn't guaranteed on any given day. Calm, low-wind mornings after a stretch of settled weather are clearest; strong onshore wind, big surf, and runoff after heavy rain stir up sand and turn the water murky and brown near shore.
Is there seaweed (sargassum) on Perdido Key beaches?
Perdido Key gets seaweed seasonally — mostly sargassum, a brown floating algae that washes ashore in patches during the warmer months when onshore winds push it in. It comes and goes day to day and beach to beach, so a weedy morning is often clear again within a day or two once the wind shifts.
