Beaches for September for Cancun

Playa Caracol

Playa Caracol is known as the last "real beach" in the north of the resort along the Hotel Zone, found in between Plaza Caracol and Xcaret Dock. This beach is made up of fine golden sand and clean waters which are often subject to strong winds that create waves. These waves provide the perfect conditions for windsurfing and sailing. There are several water sport kiosks peppered along the beach where you can hire water sport equipment. 

If you walk along the beach to where the Fiesta Americana Gran Coral Beach Hotel is, you'll find calm waters protected from waves and wind by a jetty, making them suitable for swimming and snorkelling. This beach gets very busy during the peak season, but it should begin to quiet down toward the end of September. If you're visiting at the start of the month, walk westward along the beach - you'll soon come to a quiet section where you'll find plenty of space to relax. Onsite services and amenities include lifeguards, bars, restaurants, sun loungers and parasols.

Playa Langosta

For another quiet beach, try Playa Langosta. Also set within the north of the Cancun Hotel Zone, this beach is made up of fine golden-white sand and gentle turquoise waters which are roped off so swimmers can't go too far and get swept out to sea. The sea is very shallow for a long way out, making it ideal for snorkelling. Although there are no toilets provided on the beach, there is a snack bar which sells traditional Mexican food and cool drinks, plus locals regularly walk along the beach selling fruit and homemade sandwiches. The beach is lined by loads of hotels, bars and restaurants, giving you plenty of choice when lunctime comes around.
