Swimming at Praia de Hortelã is challenging due to its rocky nature and rugged coastal conditions. The rocky shoreline creates hazards including uneven surfaces, sharp rocks, and unpredictable wave breaks. Strong Atlantic currents common along São Nicolau's coast add to the difficulty. This location is better appreciated for coastal scenery and exploration rather than swimming. If you venture into the water, wear protective footwear, stay extremely cautious, and avoid going alone. No safety services or lifeguards exist. Experienced swimmers familiar with rocky coasts should exercise extreme caution.

Plan your visit during Cape Verde's dry season from November to June for the most favorable weather and sea conditions. Given Hortelã's remote location, you'll encounter virtually no crowds regardless of when you visit. The beach is ideal for photography and coastal walks rather than swimming, making cooler months particularly pleasant. Early morning hours offer the best light and temperatures for exploration. Winter months may bring rougher seas that create dramatic scenery against the rocks. Year-round warm temperatures make visits possible anytime, though summer can be quite hot.
