Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Exploring El Arco de San Andrés guides divers through a progressively unfolding underwater landscape, starting gently over a rocky seabed. Initial descent targets a shallow 5-6 m (16-20 ft), where the rocky bottom supports early signs of marine growth.
From this initial area, topography quickly transforms, leading to a series of vibrant vertical walls. Vertical walls, often encrusted with colorful sponges and anemones, invite close inspection before terrain transitions into a broad, sloping sandy amphitheater.
Encountered at approximately 16 m (52 ft), this expansive area marks a significant shift in the dive's character, moving from confined wall diving to more open bottom exploration. A clear pathway from the sandy amphitheater leads directly to the site's most distinctive feature: a grand natural stone arch, the namesake of the location.
Navigating through this impressive geological formation is a highlight, offering a sense of passage and scale. Beyond the arch, divers access a prominent sand tongue that gradually descends, extending to the site's maximum depth of 31 m (100 ft).
A different ecosystem emerges in the deeper section of the site, where larger gorgonians frequently punctuate the sandy expanse. These provide shelter and feeding grounds for a distinct set of inhabitants not always found in shallower reef areas. An overall dive profile encourages progressive exploration, smoothly transitioning from shallower, reef-lined areas and walls to deeper, more expansive sandy stretches.
Divers can appreciate the gradual increase in depth and the changing environments encountered along the route.

Best Time to Dive
Planning a dive at El Arco de San Andrés often revolves around optimizing comfort and visibility. Summer months, particularly May through October, are generally considered most favorable, with a consistent dive score of 8 indicating optimal conditions. During this period, surface air temperatures can reach a pleasant 28.5°C (83°F) in August, complementing warmer water temperatures ranging from 22-26°C (72-79°F). Minimal rainfall throughout these months, often less than 1 mm, ensures clearer skies. While winter water temperatures cool to 14-18°C (57-64°F), and air temperatures average 13-15°C (55-59°F), a 'Good' dive score (7 or 8) confirms year-round diving is viable. However, wave heights tend to be slightly higher in winter, and wind speeds can be more pronounced, particularly in March, which could influence surface conditions.
