Costa Rica Scuba Diving: Best Time, Best Dive Sites and More

As someone who spent much of her childhood in and around water and studied to be a marine biologist, I had always wanted to get my scuba diving certification.

I completed my PADI open water certification in Costa Rica and if you are thinking about scuba diving in Costa Rica or getting your certification, here’s my experience and Costa Rica scuba diving review.

Costa Rica Scuba Diving

If you ever wondered if you need to be certified to go scuba diving in Costa Rica, you do not. Many scuba diving companies in Costa Rica offer what they call a “discovery dive” which is specifically for people who don’t have their certification.

Before getting my certification, I did a discovery dive to get a feel for scuba diving.

The two tank discovery dive from Flamingo was incredible. We did a one hour instruction in the pool before the two tank dive at Las Catalinas Islands.

While diving, the team took great care of us, checking all our equipment and making sure we were OK. We just focused on swimming and enjoying the underwater world.

Although it was windy, the water clarity was great. We saw manta rays, sea stars, eels, octupuses, whitetip reef sharks, nudibranchs and big schools of fish.

On the boat ride, we saw dolphins and humpback whales breaching!

That discovery dive lit a fire in me. Scuba diving was like entering a completely different world and I was just a quiet observer and humble guest in this foreign kingdom.

I signed up for my PADI open water almost immediately afterwards!

Scuba Diving in Guanacaste, Costa Rica (My PADI Open Water Course)

I signed up to do the course with a friend and this was our itinerary. The PADI open water course consisted of 3 in person days and 1 day of theory. I completed the theory the day before the pool instruction.

• Day 1: Pool Instruction
• This took about 3 hours. Since it was just the two of us, we had one instructor. The pool day was to get used to the equipment, learn how to put the BCDs together, how to achieve neutral buoyancy, safety stops, hand signs and more.
• Day 2: First day two tank dives at Las Catalinas Islands
• We departed from Flamingo for the Catalinas Islands, about a 30 minute boat ride. On the boat ride there, our instructor went over what we would practice during the dives so we knew what to expect.
• Day 3: Second day of two tank dives at Las Catalinas Islands
• The last day we did safety stops, compass and practiced a few more exercises. The very last dive was more of a fun dive and reinforced more exercises we practiced.
• After we completed the last dive, that was it! Our instructor signed us off and we were officially PADI open water certified!
• We went back to the office to take our picture for our certification card and I picked up my card and dive book a couple weeks later.
• Price of PADI open water certification in Costa Rica is between $400-550 per person USD.

Photos

Here are some photos from my dives. I didn’t take any during the course but I got a lot of photos on my discovery dive.

Below you can see some of the beautiful marine life at Las Catalinas Islands.

I’m excited to scuba dive more and hopefully start working towards getting my advanced!

Best Time to Scuba Dive in Costa Rica

July and August are some of the best times to scuba dive in Costa Rica because it is the humpback whale and turtle season.

I did my discovery dive in August and my course in September and we heard humpback whales singing! They were so loud, I thought they were swimming over my head!

Likewise, February is a great month to scuba dive in Costa Rica to see the giant oceanic manta rays. Water temperature is generally colder.

Humpback whales also pass through Costa Rica in January, February and mid March so you may see or hear them, especially if you scuba dive at Caño Island down in the South Pacific.

May – November is rainy season in Costa Rica. The waves were rocky when I went in August as a tropical wave was passing through the country. Many people on the boat got seasick.

If you are an advanced diver and want to make the trip of a lifetime to Cocos Island National Park, the best time for sharks is July through September.

Thankfully, I took anti-nausea medicine so I was fine (thank goodness). For our course in September, we didn’t have any wind for both days. It was sunny and very pleasant.
