Scuba Diving Costa Rica

Diving Costa Rica Overview

Costa Rica is famous among experienced divers for the big animal action off uninhabited Cocos Island, 300 miles offshore. Here are challenging, high-tension dives among hammerheads, mantas, occasional whale sharks, and other awe-inspiring creatures. Land-based dive operations fi nd a few big animals. However, they're unpredictable and the visibility is often so low you'll miss them, yet many divers like the diving. Costa Rica has great tourist destinations, is exceptionably safe.

Costa Rica Seasonal Dive Planner

Our suggestions for the dive season on the Pacific coast (the only decent diving in Costa Rica) may seem odd. The best time to go is the rainy season (May through November), even though runoff can affect the water visibility. The water clarity may be better during the dry season, but the wind blows up enough to make it almost impossible to get out to the best dive sites, which are small islands or rock outcroppings an hour's boat ride from the mainland. Visibility is a crap-shoot any time of the year, but even more so during the rainy season. However, even during the wet months there is a slight chance that offshore sites can reach almost 100 foot vis, although less than forty is more common. The best scheduling would probably be May, when the wind has died down and the rain hasn't started yet. Water temperatures run between 75° and 85° year-round.

Cocos Island, three hundred miles off Costa Rica's shore, has a rainy season from June through December. Some records show that the sharks are seen more often during this rainy season. Diving is year-round, but some of the boats are pulled out of service from mid-September to October for repairs, indicating that this is probably not the best time to dive Cocos. Also, sharks go deep in El Niño years, so these years are not a good time to see big creatures.

Beneath Cold Seas: The Underwater Wilderness of the Pacific Northwest
by David Hall

It's hard enough to take a first-rate photo of reef life in the best of conditions. Try doing it in murky, bone-numbingly cold water while wearing a dry suit with 40-plus pounds of weights around your waist, and thick, insulating gloves that make it hard to use the camera controls. That's what David Hall had to endure while photographing in Canadian waters, but those physical disadvantages make Beneath Cold Seas all the more amazing.

Hall's book successfully disputes the belief that cold-water reefs are drab and dismal. He has regularly photographed the world's most beautiful dive spots for major magazines from National Geographic to Time. While Hall's shots are taken entirely at Browning Passage in British Columbia, the reef life he shoots resides along the Pacific Coast, from Northern California up to Alaska, and they are as diverse and spectacular as any creature in Raja Ampat or Fiji.
