Key Dive Site Facts
Dive Site Overview
Exploring Blowhole unveils a dynamic underwater landscape that combines rocky formations with expansive sandy stretches, creating an engaging and often surprising dive. This site is defined by its progressive walls, which descend gradually and form a layered environment where various species find shelter and forage.
Divers can expect to traverse reef sections interwoven with clear sand channels, offering varied topography for exploration and a sense of continuous discovery. The area is known for marine encounters, ranging from smaller reef inhabitants navigating the colorful corals to occasional larger pelagic visitors traversing the open water. The distinct interplay of reef and sand creates unique microhabitats, ensuring a different observational focus on each dive, whether examining the intricate details of a gorgonian fan swaying in the current or scanning the blue for passing sharks or rays.
This diversity in structure means divers can spend ample time investigating crevices along the walls for hidden life or observing schools of fish congregating over the sandy bottom, providing a rich visual experience that rewards attentive observation.
Best Time to Dive
Seasonal shifts primarily influence the optimal diving conditions at Blowhole. From November through April, dive scores are consistently rated 'Good', with air temperatures averaging between 20°C and 24°C / 68°F and 75°F. Rainfall during these months is minimal, typically less than 0.5 mm, which often contributes to better underwater visibility. In contrast, the summer months, from May to October, see warmer air temperatures, climbing to 30°C / 86°F. During this period, dive scores fluctuate between 'Good' and 'Moderate', often due to slightly increased wave heights, up to 1.6 meters, and stronger winds, averaging around 18-21 km/h, which can impact surface comfort and entry.

Dive Experience & Conditions
The dive site's profile typically extends to a maximum depth of 15 meters / 49 feet, making it well-suited for Open Water Diver certifications and above. Underwater, conditions are consistently saline, though visibility can fluctuate based on recent swells and localized currents. Water temperature information isn't consistently reported, yet divers should be prepared for the characteristic thermal layers, or thermoclines, often experienced in Pacific waters off Baja California Sur. Currents here can range from mild to moderate, particularly along the walls and within the sand channels. Always conducted via boat entry, divers are typically dropped directly onto the site, allowing for efficient exploration of its various features.
Dive Difficulty & Safety Guidelines
Approaching this site requires divers to be mindful of its progressive walls and sandy channels, as these can create varied current patterns, depending on daily conditions. While no specific hazards are listed, standard safe diving practices are always essential. Divers should maintain buoyancy control, particularly near rocky structures, to avoid accidental contact. It's recommended to consult a dive professional familiar with the site and its present conditions before any planned dive, especially regarding local currents. A dive computer and a surface marker buoy are practical items for enhancing safety and communication.

Recommended Dive Suit
Individual comfort in the water can vary significantly from diver to diver, even under the same conditions.
For most recreational dives, 2-3mm shorty or light wetsuit should provide comfortable protection. Consider warmer surface protection (like a boat coat) due to brisk winds.
