Sargassum at Hellshire Beach (Portmore): today's conditions
First bulletin for this beach lands with tomorrow morning’s update.
Hellshire Beach sits on the southern edge of Portmore, on Jamaica's Caribbean shore, a short drive west of Kingston along the coast road. This page tracks sargassum at Hellshire Beach day by day, so you know what the sea has left on the sand before you commit to the trip.
You get today's rating, from 0 for clear sand to 5 for a heavy landing, a map that places the beach within its stretch of coast, and the recent trend that shows whether things are building or easing. The reading is rebuilt every morning, ahead of the hour when most people decide where to swim.
Hellshire Beach on the sargassum map
What to know about this beach
The beach lies on the south face of the Hellshire Hills, the dry limestone peninsula that closes Kingston Harbour to the west, and it looks due south into the Caribbean. Trade winds blow from the east, and they carry the drifting rafts that reach the region, so east facing shores take the first and largest hits. A beach angled south mostly gets what has already rounded the island's eastern tip and travelled along the coast.
That is a tendency, not a guarantee. When a raft drifts through the basin south of Jamaica, a change of swell or a southeasterly breeze can set it down on this shallow, gently shelving shore. Calm bay water then holds the weed in place longer than an open, wave washed beach would.
Frequently asked questions
Is Hellshire Beach usually spared by sargassum?
It faces due south on the leeward Caribbean side, away from the easterly trades that drive the rafts, so landings tend to be lighter than on Jamaica's eastern shores. Lighter, though, is not the same thing as none at all.
How do I check conditions before driving out from Kingston?
Open this page on the morning you plan to go. FanGass recalculates a 0 to 5 rating for Hellshire Beach each day and plots it on the coastal map, which takes seconds to read before you set off.
When is sargassum most likely on this part of the coast?
Caribbean landings cluster from spring through late summer, with May to August the busiest window in most years. Outside it, episodes still occur, but they are usually shorter and reach the shore in patches rather than in bulk.
Is Fort Clarence a sensible fallback if Hellshire is covered?
It sits under two kilometres northeast and opens to the southeast, so the two beaches do not always score alike on the same morning. Checking both ratings before you leave saves a pointless drive across the peninsula.
