Sargassum at Cardiff Hall Public Beach, Runaway Bay: today's report
First bulletin for this beach lands with tomorrow morning’s update.
Cardiff Hall Public Beach is the public stretch of shoreline at Runaway Bay, in Saint Ann, along the Caribbean-facing north coast that links Discovery Bay with Ocho Rios. It is reached from the coast road, and it is one of the busier local swimming spots in this part of the parish.
The page answers one question: how much sargassum is on Cardiff Hall Public Beach today. You get a score from 0 to 5, a map of the surrounding coast, and a bulletin rebuilt every morning rather than a seasonal average.

What to know about this beach
There is no enclosing bay here to act as a filter. The shore runs close to straight and faces due north, so anything drifting along this coastline can reach the sand without first negotiating a narrow entrance, which is what protects Discovery Bay a few kilometres west.
Two things pull the other way. Jamaica's north coast sits on the leeward side of the flow that pushes rafts in from the eastern Caribbean, so episodes here are usually smaller than on Atlantic-facing shores. And the fringing reef offshore takes the force out of the swell before it lands. That calm has a cost: the shallow water between reef and beach turns over slowly, so weed that clears the reef can sit close in rather than being carried straight back out.
Frequently asked questions
Is Cardiff Hall more exposed than nearby beaches?
It faces due north on a fairly straight coastline, with no narrow bay mouth to slow arrivals the way Discovery Bay has. Drifting weed reaches it more directly, though this Caribbean shore still sees less than east-facing coasts.
How can I check the beach before I go?
Look up the FanGass page for Cardiff Hall Public Beach in the morning. The 0 to 5 score and the map are recalculated each morning, which beats relying on a photo taken several days earlier.
Does the reef keep sargassum away?
It flattens the swell and keeps the water calm, but floating weed still crosses it. Once inside, the shallow lagoon holds material longer than an open, well-flushed beach would on the same day.
Which months are riskier at Runaway Bay?
Caribbean arrivals cluster from spring into late summer, and totals swing widely between years. Conditions can also change within a single week, so a daily reading tells you far more than a typical season.
