About this reading

The Pascagoula harbor station sits in the harbor; open-water surf can read a few degrees different.

Reading from the Pascagoula harbor station, about 20 miles away. That's a long way down the coast — treat this as the area's surf temperature, not the sandbar in front of you.

Warm water says nothing about surf, rip currents, or bacteria — check local lifeguard flags and advisories.
