Jellyfish and sea lice

What usually turns up on the Florida Panhandle and the Alabama coast, and when.

  • The drifters arrive first. The extension office here reports Portuguese man-of-war and by-the-wind sailors coming in early — one year they turned up in February — with the sea nettles and moon jellies later in the summer. UF/IFAS Extension's Escambia County office — So when are the jellyfish going to be here?
  • Which side of the island you swim on can matter more than the month: the same office notes that when jellyfish are numerous on the Gulf side they are usually not in the sound behind it, and the other way round. UF/IFAS Extension's Escambia County office — So when are the jellyfish going to be here?
  • Sea lice is more a south Florida and Caribbean complaint than a northern Gulf one — it has been reported down there for decades, and reports from this stretch of coast are not common. UF/IFAS Extension — They call it "sea lice"

This is what a season usually looks like, not a forecast of any particular week. Jellyfish drift on wind and current, so the people who watch them say there are tendencies but no guarantees — the lifeguard flags on the day beat any calendar.

About this reading

The satellite record for the water off Okaloosa Island covers about fifteen miles of open water off this beach. Nothing is in the water here — a satellite reads the surface of that whole stretch of ocean once a day, and the surf zone itself is too narrow to appear in it.

Warm water says nothing about surf, rip currents, or bacteria — check local lifeguard flags and advisories.
