Believe it or not, the best time to visit Costa Rica for scuba diving is in the rainy season. The rainy season is from May to November when it often rains every afternoon, but don’t worry it usually doesn’t last very long with most of the time being under an hour.

During these months, the visibility is the highest, the temperatures are the warmest, and best of all, youll find the most marine life.

Most tourists (except for divers) dont visit Costa Rica during the rainy season so that makes it an even better time to visit because there are fewer crowds and lower prices.

If youre a beginner scuba diver, the optimal time to visit would be from August to December because the water is very calm with little wind.

The visibility can reach 100 feet and there is still a ton to see. You really cant go wrong any time of year because there is an abundance of sea life year-round.

Costa Rica is a great place for all scuba diving levels to enjoy marine life and the underwater world in general.

Costa Rica has a unique landscape because it has both the Pacific Ocean and the Caribbean Sea on its coast.

On the left side, youll find the Pacific Ocean and there are many islands just off the shore where unique sea life lives.

The Caribbean Sea side is less developed so you may have a harder time finding hotels, restaurants, and other things to do compared to the left side of Costa Rica.

Both sides offer a ton of variety in the underwater world.

Overall, however, the Pacific side has better scuba diving and as well as more developed landscapes with better establishments.

For beginners and those new to Costa Rica, the Pacific side would be the better option to get acquainted with the area.

Most of the southern part of Costa Rica is a protected biological reserve so the sea life there is very abundant and the area is well preserved.

No matter where you choose to scuba dive in Costa Rica, youll find that exploring the underwater coast can be just as interesting as exploring the beach towns along the shore.

Best Scuba Diving Locations in Costa Rica

Below youll find a list of some of the best scuba diving locations in Costa Rica. They have been broken out between the Pacific and the Caribbean Coast.

Best Pacific Coast Scuba Diving in Costa Rica

The Bat Islands

(also known as Islas Murcielagos) are part of the Guanacaste Region on the northern Pacific Coast.

Theyre protected by the Santa Rosa National Park. It takes about an hour by boat to reach the islands and many tour companies will take you there.

Here you may find bull sharks, stingrays, turtles, and more. The bull sharks mostly stay in an area known as the Big Scare. There can be swells and a bit of a current so it’s better for more experienced divers.

The Catalina Islands

are located 2 to 15 miles offshore and they’re part of the Guanacaste province.

Theyre a popular location for scuba diving and the islands are actually rock formations from volcanoes.

The actual underwater topography is almost just as interesting as the marine animals. Youll find caves and arches covered in the coral where sea life loves to hang out.

Youll get the chance to see turtles, reef sharks, and various types of rays.

This area is best known for its manta rays which can be found here year-round. There are many scuba diving spots at the Catalina Islands but with a strong current, its best for more advanced scuba divers.

You can find a tour company to take you to the islands from cities along the northern Pacific coast.

The Gulf of Papagayo

is located in the province of Guanacaste off the Papagayo Peninsula and here youll find very calm waters within the inlets and bays.

There is a lot to do on land in this area but even better is the underwater world. Because its calm, its a great spot for beginners.

Tamarindo is a town in the Guanacaste region of Costa Rica on the northern Pacific Coast. Along the Nicoya Peninsula, many scuba tours will take out to various islands off the coast. Scuba diving is one of the many things to do in Tamarindo.

If youre visiting Costa Rica and want to pick a general spot to stay for your trip that offers some great scuba diving options, Tamarindo is your place!

Youll have the chance to join many scuba diving tours from this area that will take you all over, including the islands off-shore.

The Tortuga Islands

are off the coast of the Nicoya Peninsula in the Gulf of Nicoya. Youll find canyons and three shipwrecks within the scuba diving range.

The shipwrecks include two Coastguard ships and another boat 100 feet underwater. One of the shipwrecks is only 52 feet deep so novice divers can really get close and personal to it.

However, the underwater topography is also amazing here and it is full of marine life! Its also very cool to see how the sea life turns the shipwrecks into homes as they do with coral reefs.

Reef sharks are even known to inhabit the 100 foot boat. Its a great place for divers all of the experience levels because there is a mix of shallow and deep sites.

Caño Island

is part of a biological reserve and is located 10 miles off the Osa Peninsula in the Puntarenas Province.

It has visibility between 30 to 100 feet year-round. Youll find white-tip and bull sharks, dolphins, and schools of fish in the hundreds. There are 5 locations designated for diving at this biological reserve so there are options to choose from. If you have the chance, try them all!

Cocos Island

is located 340 miles off the coast so it’s a bit more expensive than other tours but its well worth doing a liveaboard here.

The ocean is deep around the island but the island has pinnacle and reef walls that attract tons of sea life.

There are 20 different dive sites and you may see various sharks, large schools of fish, turtles, dolphins, rays, and sailfish.

One of the best diving spots in this area is Bajo Alcyone. There can be a strong current so its not recommended for beginners.
