Sargassum at Fort Clarence Beach (Portmore): today's report
First bulletin for this beach lands with tomorrow morning’s update.
Fort Clarence Beach opens on the same Portmore sand belt as Hellshire Beach, which lies under two kilometres to the southwest, on Jamaica's Caribbean coast. This page gathers what matters about sargassum at Fort Clarence Beach before you make the drive.
Three things, updated every morning: the day's rating, from 0 for clean sand to 5 for weed across the shoreline; a map that sets the beach inside the island's southern stretch; and the last few days of readings, which show whether an episode is growing or fading. The point is a decision based on today's coast rather than last week's.

What to know about this beach
Orientation is what separates this beach from its neighbour. Fort Clarence faces southeast, lined up with the trade winds that sweep the Caribbean from east to west, while the shore a short way down the coast turns due south. A raft moving along Jamaica's southern flank therefore meets a beach angled to catch it rather than to let it slide past.
The setting matters too. This is a long, low sand belt backed by the dry Hellshire limestone hills, with a gently shelving bottom and few rocky points to break up what comes ashore. When a landing does happen it tends to spread along the strand and to sit there until wind or current takes it back out to sea.
Frequently asked questions
Is Fort Clarence more exposed than nearby Hellshire Beach?
On paper yes, because it opens southeast, towards the direction rafts come from under the trade winds, while its neighbour faces due south. The gap is small, and the daily ratings are what confirm it.
How can I tell whether the sand is clear before coming?
Check the FanGass morning rating, from 0 to 5, together with the map of the Portmore stretch. It is recalculated daily, so you are not relying on an old photo or a friend's memory of last month.
Which months call for closer attention here?
May to August carries most Caribbean landings, with quieter weeks inside the season all the same. Between November and March arrivals become uncommon on this piece of coast, without ever being ruled out entirely.
What are my options if a landing is flagged for my date?
The Portmore sand runs for kilometres and conditions differ from one access point to the next. Look at Hellshire, a few minutes down the road to the southwest, before writing off the day altogether.
