Sapphire Beach is looking fair today, a bit choppier than its usual glassy self, but still inviting. That 14.7 mph ESE cross-onshore wind is definitely stirring things up a bit on this east-facing beach, keeping the surface textured despite the sub-1 ft surf. Good news on the clarity front though, with only 0.01 inches of rain recently, the estimated visibility today is 20-30 ft, so those turtles should still be easy to spot.

Site Notes
East-facing — exposed to trade wind swells. Best on low wind days. Sandy entry with reef and sea grass patches offshore. Great for sea turtle sightings.
