Andrew Bay Beach is a sheltered cove south of Ngapali's main strip, offering generally calmer waters than more exposed beaches, making swimming relatively safe during the dry season (November to April). The protected bay configuration reduces wave action and currents. However, conditions vary with seasons—avoid swimming during monsoons (May-September) when seas become rough. No lifeguard services are present, so swim cautiously and assess conditions yourself. The turquoise water is inviting for couples and snorkelers, though visibility depends on recent weather and tides.

For the best combination of good weather and fewer crowds, visit Andrew Bay Beach in November or late February through March. While the peak season runs December to January with optimal conditions, these shoulder periods still offer excellent weather with noticeably fewer tourists. The bay's tucked-away location south of the main resort strip means it naturally attracts fewer visitors year-round. Weekdays are quieter than weekends. October and April can work for budget-conscious travelers willing to risk occasional rain for near-empty beaches.
