Best Time of Year to Scuba Dive in Costa Rica
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, you’ll find the most marine life.
Most tourists (except for divers) don’t 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 you’re 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 can’t 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.
Best Places to Scuba Dive in Costa Rica
Costa Rica has a unique landscape because it has both the Pacific Ocean and the Caribbean Sea on its coast.
On the left side, you’ll 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, you’ll 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 you’ll 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.
They’re 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.
They’re 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. You’ll find caves and arches covered in the coral where sea life loves to hang out.
You’ll 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, it’s 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 you’ll 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 it’s calm, it’s 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 you’re 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!
You’ll 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. You’ll 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! It’s 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. It’s a great place for divers all of the experience levels because there is a mix of shallow and deep sites.

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 it’s not recommended for beginners.

However, the dive sites they do have on the Caribbean coast are amazing.
Uvita Island is part of the Limon province and is just offshore. It’s a great spot to check out and there is also a shipwreck in this area.
