OCEAN SAFETY
During the year, Seychelles sees two seasonal shifts. The beginning and end of the seasons are less predictable than in past years, however, the northwest monsoon season normally runs from December to March, and the southeast trade winds provide a drier and somewhat colder season from May to September. This has an impact on currents and waves.
Beaches that are safer for swimming at some periods of the year might be deadly at other times. In general, the west coast is impacted by the northwest monsoon, whereas the east coast is impacted by the southeast winds. Swimming is not permitted at any time on the southernmost beaches. Swimming should be done with caution, especially with youngsters. Strong currents can cause drownings. Before visiting the beaches of Seychelles, seek local information regarding the weather. Follow beach signs and keep within your depth. When the water is rough, dangerous rip currents can form off the popular Beau Vallon beach (and nearby beaches).
Beaches do not usually display safety information, so don't assume they're safe. Lifeguards are scarce, however, some are stationed on major beaches. Inquire with hotel employees about the conditions and safety of surrounding beaches. This is one of the things you need to know before traveling to Seychelles for a fun and safe trip.
