Cabo San Lucas Liveaboard Diving

Cabo San Lucas sits right where the Sea of Cortez meets the Pacific, giving it a mix of calm, sheltered reef diving inside the bay and more exposed, current-driven sites further out. Depths at most local sites range from 30–80 ft (9–24 m), suiting a range of experience levels, with sea lions, rays, and tropical reef fish commonly sighted. It's also the main departure port for liveaboards heading to the more advanced Revillagigedo Archipelago further offshore.

Los Cabos — the broader region covering Cabo San Lucas and San José del Cabo — offers diving on both the Pacific and Sea of Cortez sides, with the calmer Sea of Cortez side generally preferred for beginners and the Pacific side seeing occasional bigger pelagic action. Water temperature swings from around 70°F (21°C) in winter to 85°F (29°C) in summer. Most diving here is day-boat-based, distinct from the multi-day liveaboards that depart from the same marina for Revillagigedo.

Water temperature in Cabo San Lucas ranges from around 70°F (21°C) in the cooler winter months to roughly 85°F (29°C) at the peak of summer. A 3mm wetsuit is generally comfortable from June through October, while a 5mm suit is more comfortable the rest of the year. Visibility is typically best when the water is warmest, from August through November.

Whale shark season around Los Cabos and the nearby Sea of Cortez runs roughly October through April, with sightings most concentrated closer to La Paz, about two hours away, than right in Cabo San Lucas itself. Sightings depend on plankton blooms and shift somewhat year to year, so it's worth checking current conditions closer to travel. Most encounters are snorkel-based rather than scuba, since the sharks feed near the surface.

Yes, though most operators running whale shark trips from Cabo San Lucas actually transfer guests to La Paz, about two hours away, where sightings are far more reliable during the October–April season. Encounters are done by snorkeling alongside the sharks rather than scuba diving, since they feed near the surface. Operators enforce distance rules to avoid disturbing the animals.

Local favorites near Cabo San Lucas include Pelican Rock and Land's End, both offering shallow reef diving with sea lions and colorful invertebrates close to the marina, and Neptune's Finger, known for its underwater sand falls. Gordo Banks, a pair of deep seamounts further along the coast toward San José del Cabo, attracts more advanced divers hoping to see pelagic sharks and rays in open water. Most sites are reachable within a short boat ride from the marina.

Whale shark tours typically include round-trip transport (often to La Paz, where sightings are more consistent), snorkel gear, a guide, and time in the water alongside the animals under strict no-touch, distance-based rules. Trips usually run as a half or full day and don't require scuba certification, since encounters are snorkel-only. As of 2026, prices and specific transfer arrangements vary by operator, so it's worth confirming details when booking.

Local shark diving out of Cabo San Lucas targets open-ocean species like mako, blue, and silky sharks, along with smooth hammerheads depending on season — a distinctly different product from the Guadalupe Island great white cage diving that departed from San Diego before Mexico's 2023 ban. Trips typically head out to deeper water beyond the bay, since these species prefer open water over the reef, and are often run as cageless snorkel or freedive encounters rather than scuba. Species vary by season: mako and blue sharks favor the cooler winter water, while silky sharks are more common in summer.

Whale shark snorkeling trips typically depart from Cabo San Lucas for the Sea of Cortez near La Paz, where whale sharks gather seasonally from October through April to feed on plankton. Guests snorkel alongside the sharks at the surface rather than diving, following operator rules on distance and group size to protect the animals. It's a family-friendly activity that doesn't require any dive certification.

Cabo San Lucas waters host sea lions, mobula and eagle rays, sea turtles, and a range of reef fish close to shore, with pelagic species like dolphins, whales, and various shark species further offshore. Seasonal highlights include humpback whales from roughly December through March and whale sharks nearby from October through April. The mix of Pacific and Sea of Cortez influences gives the area unusually varied marine life for its size.

Yes — several dive shops in Cabo San Lucas offer PADI Open Water and advanced certification courses, typically combining classroom or e-learning with pool and open-water training dives at local sites like Pelican Rock. Courses usually run 3–4 days, and many shops can accommodate certification alongside a broader vacation itinerary. Warm, calm water on the Sea of Cortez side makes it a comfortable place to learn.

Cabo San Lucas diving packages typically bundle multiple days of two-tank boat dives with gear rental, hotel transfers, and sometimes accommodation, depending on the operator. Packages aimed at certification combine training days with fun dives once guests are certified. As of 2026, it's worth confirming which specific sites are included, since packages vary between local reef diving and add-on trips to Cabo Pulmo or Gordo Banks.

Yes — Cabo San Lucas is the primary departure port for liveaboards heading to the Revillagigedo Archipelago (Socorro, San Benedicto, and Roca Partida), with the crossing taking roughly 24–30 hours each way. It's also occasionally used as an embarkation point for Sea of Cortez liveaboards heading toward La Paz and the Midriff Islands. Local day-boat diving around Cabo is a separate, more casual offering than these multi-day trips.

Most local Cabo San Lucas dive sites, like Pelican Rock and Land's End, are suitable for beginner and intermediate divers given their shallow depths and generally calm conditions. More advanced sites like Gordo Banks involve open water, depth, and current, making them better suited to experienced divers. This range makes Cabo a reasonable place to start diving before attempting more demanding trips like a Revillagigedo liveaboard.

Cabo San Lucas dives well year-round, but conditions are generally calmest and warmest from June through November, while whale shark and whale watching season (roughly October through April) adds seasonal wildlife interest. Hurricane season, roughly July through October, can occasionally disrupt trips with short-notice weather. As of 2026, most local operators run daily trips unless disrupted by storms.
