Backwash Bay is primarily a surf destination, and water safety depends on your surfing ability and ocean experience. The bay attracts surfers precisely because of its waves, which can be powerful and challenging. Non-surfers should be extremely cautious about swimming, as conditions can be rough with strong currents. There are no lifeguards at this remote cove. Even experienced surfers should assess conditions carefully and never surf alone. For non-surfing visitors, enjoying the scenic cove from shore is the safest option. The tucked-away location means help is not readily available in emergencies.

For surfers, the best swells typically arrive during the wet season (May to November) when Pacific storms generate consistent waves, though surf can be found year-round. Dry season (December to April) offers better weather for accessing the bay and enjoying the scenic setting with less rain. For fewer crowds, avoid peak holiday periods and weekends when surfers from Puerto Jiménez and nearby areas visit. Early mornings provide the best light for photography and often the calmest winds. The tucked-away nature means it remains relatively uncrowded compared to more famous surf spots.
