West Coast Diving – Colombo

World Class Wreck Diving off the City


The busy commercial capital of Sri Lanka is one of Asia’s best kept diving secrets. With over 10 wrecks Colombo offers world class wreck diving in close proximity to the international airport and a major city. Explore the immense cargo holds of intact freighters such as the Pecheur Breton (Cargo Wreck ) and theMedhufaru, play with the friendly lionfish at the Nilgiri Tug or discover history on WWI wrecks such as the SS Perseus. Most wrecks are in the 20-30m depth range and easy to access being less than 30 minutes boat ride from our base.


But Colombo diving is not limited to wrecks. Wide angle enthusiasts can explore current swept outer reefs with soft coral and massive gorgonian sea fans while macro photographers can search for nudibranchs, crabs, shrimps, electric rays, pipefish, sea moths and other critters on the rocky reefs. Our wrecks also teem with marine life, from large schools of snappers and fusiliers to visiting pelagics such as dogtooth tuna, wahoo and eagle rays. For novice divers, Colombo offers a challenging but rewarding environment to advance your training by taking the Advanced Open Water course or specialty courses like Nitrox or Deep Diver with training dives possible on world-class wreck sites.



In Colombo, Island Scuba is based at La Voile Blanch on Mount Lavinia beach, 13km south of the city center. It takes around 20-30 minutes to reach the dive center from the city center.

Dive Season:

Our Colombo dive center is open from November 1st to April 10th.


Weather and Conditions:

The best conditions are generally in February and March. December and early January can have strong northerly winds that affect offshore diving on some days, especially towards afternoon. Currents are generally mild to moderate but strong currents may occur on some offshore sites. Deeper sites can be challenging during strong currents due to blue water descents and ascents and hence are reserved only for divers with proof of deep diving experience. November to early December have regular evening rains, but the daytime is usually dry. January to March is the driest period in Colombo with long hot sunny days. Average water temperature is around 28C. A 3mm Shorty wetsuit is more than adequate for most divers.



Average visibility on most inshore reefs and wrecks is around 10m, while visibility in excess of 30m is not uncommon on offshore sites. Some of the reefs closest to shore that are mostly used as training sites are more affected by sediments and visibility may drop to as low as 3m.
