Sargassum at Cayman Kai: today's conditions
Clear
Clean, hit it
Cayman Kai lines the northern reef coast of Grand Cayman, between the North Sound and the open sea, in the district of North Side. This residential shore of barefoot villas appeals to visitors renting a house away from the big hotels, a short hop from Rum Point.
Every morning this page sums up the day: a 0 to 5 rating for this stretch of sand, the north-sector map and what has changed since yesterday. Handy for choosing, over coffee, between Cayman Kai's reef lagoon and the sheltered coves of the Sound next door.

What to know about this beach
Unlike its neighbours inside the lagoon, Cayman Kai looks out to sea: oriented north-east, it opens onto the island's outer reef coast. It still sits far from the main front, since the trade-wind flow greets Grand Cayman at Colliers in the east and along the south shore long before it considers the northern side.
Its own sensitivity comes with north and north-east components, which press drifting mats straight onto this stretch. The barrier reef running offshore then breaks up part of the rafts and traps others on the seaward side. Of the three beaches tracked in this zone, Cayman Kai is the earliest to react, a step or two above Rum Point and Starfish Point, nestled in the Sound.
Frequently asked questions
Why does Cayman Kai's rating differ from Rum Point's?
They are almost side by side, but Cayman Kai faces the outer reef while Rum Point hides inside the North Sound. On a north wind one takes the brunt while the other often stays untouched.
What does the barrier reef do for the beach?
It breaks the swell and holds part of the rafts on the seaward side. Whatever gets through the passes arrives in fragments, which limits large single landings on the sand.
Which wind pushes the rating up at Cayman Kai?
North and north-east components, which drive the mats straight onto the reef coast. Under a classic easterly trade wind the flow heads for Colliers and the south shore, leaving Cayman Kai out of the way.
When should I watch this sector more closely?
From spring to late summer, when Caribbean pulses multiply, and above all whenever a shift to northerly wind is forecast. The morning rating folds those changes in day after day.
