AI Spot Summary
Mauna Kea is looking glassy and inviting this morning, with the calm surface conditions making for an easy entry over the sand. While the rising tide is currently the main factor keeping things a bit sluggish, the lack of swell is keeping the water crystal clear. The estimated visibility today is 50-60 ft, and with that light WSW breeze, the bay remains well-protected from any real chop.
