Cold Water & Deep Dives

Cold Water Dives

For prepared divers, cold water dive sites are some of the most beautiful and biologically productive areas in the world.

The water temperature at the wrecks is usually around 52 degrees year-round. The kelp and the Coronados are usually a bit warmer.

The vis at Wreck Alley averages around 20’ (some days can be 10’ and others can be 60’+), and the vis at the Coronados averages around 40’ (I’ve seen it up to 80’+).

If you are not used to confining cold water apparel and the typical vis, or you don’t have much cold water diving experience (more than 20 cold water dives) then you probably should have a guide. Guides are available, contact us for details.

Deep Dives

We offer deep wreck dives for EXPERIENCED DIVERS ONLY. These dives are not for everybody. Level of dive certification will be checked before the dive. A minimal level of Advanced or Deep Diver certification is required. We also require the diver to show record of at least 25 cold water dives.
