AI Spot Summary
Shark's Cove is looking like a sleepy, glassy basin today, though the water clarity is feeling a bit muted compared to its usual crystal-clear standard. With minimal swell and barely a whisper of NNE wind, the surface is calm enough for an easy lava rock entry, but that recent light rainfall has stirred up some sediment near the shore. The estimated visibility today is 20-30 ft, so expect a slightly hazy experience while cruising the reef.
