Sargassum is a type of floating seaweed that forms large mats in the ocean. While it's essential for marine life in the open sea—providing food and shelter—when it reaches the shore in excess, it can:

• Emit a foul odor as it decomposes
• Change the color and clarity of the water
• Accumulate on the shore, making it uncomfortable to swim or walk

In recent years, the sargassum problem has become more frequent and intense, mainly due to climate change and increased nutrient levels in the Atlantic Ocean.

In recent years, sargassum has seriously impacted countries and popular tourist destinations across the Caribbean, especially in eastern Mexico (Quintana Roo)—including Cancún, Playa del Carmen, Tulum, and the Riviera Maya. It has also been reported in Belize, the Dominican Republic, Jamaica, Cuba, Puerto Rico, and some of the Lesser Antilles. Even parts of southern Florida have experienced temporary buildups. This issue affects not just travelers, but also local fishing, coastal biodiversity, and the tourism-based economies of many communities.

Sargassum presence varies daily depending on the weather, ocean currents, and wind direction. However, some areas are naturally more protected and tend to have little or no sargassum. Here are some top picks:

• Location: Just 20–30 minutes by ferry from Cancún
• Why go: Playa Norte faces west, which protects it from direct sargassum currents. The water is shallow, clear, and perfect for swimming.

• Location: Accessible by ferry from Playa del Carmen (45 min), then a taxi to the beach
• Best for: Snorkeling, relaxing, and underwater photography. These beaches on Cozumel’s west side are usually sargassum-free.

• Location: 2.5 hours by car from Cancún, plus a 20-minute ferry ride
• Why visit: Peaceful, pristine beaches with turquoise water. Thanks to its geographical position, Holbox tends to receive very little sargassum.

• Highlights: While still in Cancún, this area is somewhat shielded and usually has less sargassum than other parts of the Hotel Zone.
• Tip: Great for snorkeling thanks to its clear, calm waters.

• Location: Tucked away in the Cancún Hotel Zone, near shopping centers like Plaza Caracol
• What makes it special:
• Small and serene, with low tourist traffic
• Calm, pool-like waters perfect for swimming
• Conveniently close to restaurants and stores
• Naturally more protected from sargassum due to its location and orientation

• Check real-time sargassum maps, such as those from the Red de Monitoreo del Sargazo en Quintana Roo on social media
• Choose hotels that actively clean their beachfront areas—ask before booking
• Stay flexible so you can explore alternative beaches if one is affected

Sargassum doesn’t have to ruin your vacation. With a bit of planning, you can find clean beaches, clear water, and unforgettable Caribbean experiences near Cancún. From Isla Mujeres to Playa Ancha, the Mexican Caribbean remains one of the best places in the world to relax—sargassum or not.
