The Best Locations and Times to Dive in The Caribbean and Pacific Coast

It’s important to make a distinction between those two words; need and want. What you want to do might not necessarily what you need to do.

For example; You may want to dive in open waters that are a 1000ft deep. But if your diving experience stretches to a quick snorkeling session 15 years ago – what you need will be widely different to what you want!

Luckily, with the huge array of diving spots available in Costa Rica, there’s something for everyone. Whether you’re a beginner, intermediate or advanced diver, Costa Rica can provide you with beautiful reefs, crystal blue waters and the most unique marine life in the world.

You just gotta know where to look…


Best Time to Dive in Costa Rica

If you’re looking to dive in Costa Rica it’s important to take note of the countries seasons. Seasons can be split into two categories; dry season and wet (or rainy) season.

Generally speaking the best time to dive in Costa Rica will be during dry season. Your safest bet would be between the months of December to April. Outside of these months, depending on where you are in the country, the weather can be hard to predict.

That said however, each month, whether dry or wet offers a different experience depending on where you want dive. Here’s a quick breakdown of each month;

  • December – April

Dry season can present a good time to dive for beginners as the water tend to be calmer. You’ll get to see the ‘underworld’ in all its colorful glory and experience visibility levels that can reach up to 100 feet.

Diving spots near Guanacaste and Quepos are good locations to plot up if you’re looking to dive around this time of the year with the Catalina Islands being a particularly good spot.

  • May – November

This time of the year is considered Rainy Season. Again, weather conditions can be hard to predict. A general rule of thumb is to expect a rain shower or two around mid-afternoon.

As a recommendation, we do not advise complete beginners to dive within these months. With more volatile waters and less visibility, diving around this time of the year is usually recommended for more advanced divers.

But, as mentioned above, depending on the location you choose you can still find a great spot to dive – no matter what your skill level is.
