AI Spot Summary

Sapphire is feeling a bit churned up today, with that persistent 18.8 mph E wind pushing onshore and keeping the water from settling into its usual crystal-clear state. While the minimal rainfall is a plus, the trade wind swell is definitely stirring up the shallows, and the estimated visibility today is 15-20 ft. It is a rising tide, but those sea turtles might be keeping their heads down in the seagrass until the surge calms.

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.
