I just spent most of the last 2 weeks in sunny Akumal with my family, swimming a couple of hours every day from a beachfront condo on Half Moon Bay called Yool Caanal. Mostly around 80F, air temp and water temp. Very nice. Here's the view from our deck (right).
Thanks to the supremely hot Mrs blogfish (left) for making the vacation memorable, and for my birthday present of a nice underwater digital camera so I can show you some of the fun.
Here's the number 1 boo as she's snorkeling in the ocean for the first time at age 7 and seeing coral reefs, fish, a turtle, etc.
Here's boo number 2 learning to snorkel at age 4, and looking at what he called "inifinity fish" after swimming through vast schools of sardines.
I'm so impressed to see these two little boos snorkeling in the real ocean. A dive instructor friend said that kids this young can learn, and these two are definitely not too young.
They did some swimming and I did some towing and we got out to look at coral reefs despite a few bouncy waves now and then, sponges that looked like they were sending creepy fingers up to grab little toes, and some big scary-looking fish like
barracuda and greater amberjack.Here's a small sample of what we saw underwater (hope the IDs are right). Click photos to enlarge.
