Islamorada

Overview

Islamorada is a village of six islands in the Upper Keys, styling itself the Village of Islands, and it is known worldwide as the sport-fishing capital: the charter fleet, the backcountry flats and the offshore grounds are what bring people here.

Sand is not. Like most of the Keys, Islamorada has very little natural beach, and the shoreline is largely mangrove, rock and shallow flats. Founders Park on Plantation Key has a man-made beach and is the main public option; Anne's Beach at the southern end is a shallow tidal flat backed by boardwalk.

Understanding that before arriving is the single most useful thing on this page. Visitors who come for a beach are usually disappointed; visitors who come for the water are rarely so.

Position relative to the Atlantic sargassum belt

The Keys sit directly in the path sargassum takes out of the Caribbean. Weed carried west across the tropical Atlantic enters the Caribbean, tracks past the Yucatán, and turns north through the Florida Straits in the Florida Current, which runs immediately south of the island chain before becoming the Gulf Stream along the mainland coast.

Islamorada is in the Upper Keys, closer to the mainland than Key West and slightly off the strongest part of the flow, which is why the Upper Keys generally read a little better than the Lower. It is still squarely on the route.

What makes an arrival look severe here is the shoreline rather than the volume. The water is very shallow for a long way out, so rafts ground close inshore; there is almost no wave energy to break weed up or carry it back out; and the seagrass beds and mangrove fringe hold floating material rather than letting it pass. The result is thick accumulation along a narrow waterline rather than weed spread thinly across a wide beach.

The reef offshore adds the usual complication. It intercepts a good deal of what is coming, so the dive and fishing grounds can be affected while the shore is not, and the reverse is equally true. A report from the reef says little about the shoreline.

The sargassum season

In the Keys the season runs from roughly late spring into late summer, heaviest between May and August, with little through the winter. Because arrivals accumulate rather than clear, the difference between a good and a bad visit is measured in days, and the dated record is worth checking immediately before travelling.

The Florida picture in full, including how the season has changed, is set out in our Florida sargassum season guide.

Swimming conditions and safety

Where there is water access it is shallow and calm, with no surf, over sand, seagrass and rock. Water shoes are genuinely useful rather than optional, and grass beds hide urchins.

Boat traffic is the real hazard. This is one of the busiest recreational fishing corridors in the United States, and channels here carry constant traffic; swim inside marked areas and use a dive flag if snorkelling from a boat.

Lifeguard cover is limited to Founders Park during posted hours; most of the shoreline has none.

On sargassum: fresh weed in the water is harmless. The strong sulphurous smell this shoreline develops comes from thick material decomposing over several days and releasing hydrogen sulphide, and small stinging organisms live in the weed, so walk around a fresh line rather than through it.

Choosing a hotel on this stretch

Islamorada has a good spread of accommodation for the Keys: fishing lodges, mid-range hotels and a handful of resorts with their own maintained sand, plus rentals on the canals.

The question to ask a property here is about water access rather than beach: whether it has a dock, a swimming area or a boat ramp, since that is how the Keys are used. Properties with their own imported sand tend to clear it, which matters during the season.

Visitors whose priority is a beach should look at Bahia Honda State Park further down the chain, which has the best natural sand in the Keys and which we track separately.

Access and parking coordinates

Islamorada is reached by the Overseas Highway from the mainland, around an hour and a half from Miami. There is no rail service and public transport is minimal, so a car is effectively necessary. Miami International Airport is around two hours by road and Key West International about an hour and a half.

Check live conditions before you go

The Keys accumulate what arrives rather than passing it on, and a shallow shoreline makes a modest arrival look severe. On the live map we track Islamorada with dated photographs and a current condition score, so you can compare it against Key Largo, Bahia Honda and Key West on the same morning.
