Red flag warnings are posted during rough weather, particularly October-December during monsoon season when swimming becomes dangerous. Be aware of occasional jellyfish, especially during transitional months. The central area near beach clubs can get crowded with jet skis and water sports, so swim in designated areas and stay alert to boat traffic.
