Live seaweed, water clarity & which Caribbean destination is better today
Grace Bay at Turks & Caicos is protected by one of the world's largest barrier reef systems, which acts as a natural sargassum filter. The reef disrupts the sargassum's drift path before it reaches the beach, and TCI's position north of the worst sargassum currents keeps it consistently low. Grace Bay has 12 miles of unbroken white sand — it has topped TripAdvisor's World's Best Beach list multiple times for a reason.
Cancún's Hotel Zone is directly exposed to the Caribbean Sea on its eastern edge (Playa Delfines and the south end face the most risk). The northern Hotel Zone beaches — Playa Las Perlas to Playa Gaviota Azul — have better protection and are the first to get cleared. From May through October, sargassum arrives at Cancún with varying intensity — some years light, some years severe. The Mexican government and major resorts run active cleanup, but the volume can overwhelm their capacity during peak sargassum weeks.

For the best beach experience in the Caribbean: Turks & Caicos. Grace Bay is genuinely one of the most beautiful beaches on Earth — 12 miles of powder white sand with warm, turquoise, reef-protected water. If budget allows, this is where to go for a pure beach holiday.
For a budget trip with culture and convenience: Cancún wins. More direct flights, better all-inclusive value, and access to Mayan ruins and cenotes make Cancún the smartest budget pick. Choose the north Hotel Zone beaches, travel November through April, and the seaweed risk is minimal. For the price of one Turks night, you can spend three nights at a Cancún all-inclusive.
