Key Dive Site Facts
Dive Site Overview
The unusual name of Ballbuster originates from the substantial 23 kg (50 lb) lead weights, or "balls," that commercial fishing operations frequently snagged on its rocky submerged structure. Located approximately 2/3 mile from the Coral Street entry, Ballbuster is exclusively a boat dive, not accessible from shore.
It centers around a prominent subsurface pinnacle that ascends dramatically from the seafloor at a depth of about 33 m (110 ft) to around 21 m (70 ft). This distinct topography, resembling an underwater island, creates an isolated yet vibrant ecosystem that draws a significant amount of marine activity. Due to its exposed position to strong currents and proximity to the open ocean, Ballbuster presents a challenging yet profoundly rewarding dive for experienced individuals, boasting diverse and abundant sea life.
Divers planning a visit must be prepared for dynamic current conditions, which can shift and intensify quickly around the pinnacle. Much of the relatively small pinnacle can be thoroughly explored during a single dive, making it a favorite for repeat visits.
Commercial operators regularly service this area, providing the most reliable way to find the site and ensure conditions are suitable for safe diving.
Best Time to Dive
Optimal diving conditions at Ballbuster generally align with the summer months, from May through October, which frequently offer a "Good" dive score in July and August. During these peak months, air temperatures are at their warmest, averaging around 14.4°C (July) to 16.0°C (September), with significantly less rain, often below 0.3 mm per month. Surface conditions also tend to be calmer, with wave heights decreasing to averages of 1.34-1.42 m and wind speeds moderating to about 16 km/h. While overall visibility can vary widely from 10-20 m (33-66 ft), historically, winter months have sometimes provided exceptional clarity, with reports of visibility reaching 24 m (80 ft) on good days. Dive scores dip to "Poor" in February and March, primarily due to higher wave heights and wind speeds, making these periods less advisable for general diving.

Dive Experience & Conditions
Approaching Ballbuster by boat typically involves locating the site via GPS, as the pinnacle remains submerged without surface reference points. Divers must descend and ascend along the anchor line due to frequently strong currents. The site offers a dramatic wall dive, with the pinnacle rising from depths around 30 meters to approximately 18 meters, completely covered in invertebrate life. You'll navigate through rocky outcrops and kelp forests, exploring countless crevices and cracks. Visibility in Monterey can be inconsistent, commonly ranging from 10-20 meters, though 14 meters has been reported, and exceptionally clear days might push it up to 24 meters. Water temperatures vary from 10-14°C (50-57°F) in winter to 12-18°C (54-64°F) in summer, necessitating appropriate thermal protection.
Dive Difficulty & Safety Guidelines
Divers considering Ballbuster should approach this site as an advanced dive, primarily due to the consistently strong currents and the potential for moderate surge. It's critical to conduct your descent and ascent along the anchor line to manage these conditions effectively. Furthermore, the maximum depth often exceeds 100 feet, requiring divers to be proficient in deep diving procedures and air management. Overhead boat traffic, including numerous commercial and private vessels transiting to and from the harbor, poses an additional surface hazard. Always carry a surface marker buoy (SMB) to enhance visibility to boats, especially if you surface away from the anchor line. Responsible diving practices also mean refraining from hunting, as the site is close to the Pacific Grove Gardens State Marine Conservation Area, which prohibits such activities.
