Diving in the Coronado Islands

Explore diving in the Coronado Islands

Located just six miles (9.5km) off the coast of Mexico and 15 miles (24km) south of San Diego in the USA, Los Coronados Islands are a favorite destination among divers in the area due to their semi-tropical environment. Here you’ll find kelp forest, a new wreck, rocky reefs and caverns.

These sites can be reached by overnight liveaboard from the American city or as a day trip by speedboat from Mexico. A few of the dive sites at Los Coronados are protected and suitable for beginners.

However, a majority of the sites are subject to open ocean currents and should only be attempted by intermediate and advanced divers.

When to dive in the Coronado Islands

June to November is considered the best time to dive in the Coronado Islands. Liveaboards set sail for these islands from San Diego at this time, because the water conditions in the north Pacific are warmest during these months.

The weather is generally sunny with occasional rain showers. In June and July, the temperatures and humidity rise. The weather at this time transitions from hot and humid to cooler with a bit of rain.

On the other hand, December to May features the best visibility and is not as busy as the summer months in terms of tourism. You should be able to snag some good deals if you book far enough in advance.
