Huck and I re-acquainted ourselves with the Coral Gardens, where we'd last gone diving in October. This time we were joined by a friend of ours who is new to diving. Since the Coral Gardens are within the Humpback Whale National Marine Sanctuary, and this is the season for whales, the dive was eerily serenaded by Humpback whale song. We entered the dive site by swimming out from Grandma's beach, where you can park just north of the tunnel.
One difference we noted from October was the wind chop, which clouded the water near the surface. The other was the many Hawai'ian green sea turtle (Chelonia mydas): we'd only seen one or maybe two in the autumn.
