Diving in Louisiana

Quick facts

  • Every year, about 7-10 days after the full moon in August, usually between 9 p.m. and midnight, several coral species of the Flower Garden Banks participate in a mass spawning event. At this time, coral heads release their gametes into the water column where they can mix and fertilize, later becoming larvae that settle to the bottom and start new coral colonies.

Louisiana is one of the Gulf States. To the east of Louisiana lies the state of Mississippi and to the west lies the state of Texas. The state capital is Baton Rouge, although the largest city is New Orleans in which there is a strong French influence. The average high temperatures for July/August in Louisiana are 91F/32C and for January/February are 63F/17C.

In Texas and Louisiana, there is mainly lake diving and scuba parks where buses, cars etc. have been sunk. These are great for learning, but for real diving, go to the Flower Garden Banks National Marine Sanctuary.

  • During the January/March period, it's not unusual to see large schools of Scalloped Hammerhead sharks. Scientists don't truly know the reason for this seasonal schooling, but have noted that it's a regular occurrence in this part of the Gulf of Mexico and that all of the sharks appear to be male! Schooling Spotted Eagle Rays are also frequent visitors.
  • July, August and September bring the possiblity of seeing Whale Sharks. They seem to prefer the calmer surface conditions typical of that time of year as they cruise along gulping great quantities of plankton.

Getting there

  • Flower Garden Banks National Marine Sanctuary - the reef is at a depth of 60 feet. Huge coral heads stretch as far as the eye can see. In fact, there is so much coral, about 51% coverage, that it's often hard to see the fish, as they have so many places to hide. Bluehead and Yellowhead Wrasses, schools of Chromis and Creolefish, and a variety of Damselfish are the most prevalent above the reef.

Regardless of your destination, check your local travel advisory board or department for travel advice about that location when planning your trip and again shortly before you leave.
