How to Identify a Rip Current (Rip Tide)

• An area of calm or rippled water in between even-breaking surf
• Discolored water due to sand being stirred off the bottom.
• Darker colored water (deeper because the current dredges the bottom)
• Foam on the surface extending beyond the surf line.
• Debris floating seaward
• Lower, choppier wave heights
• Relax and stay calm. If you get caught in a rip current, float with the current or swim across the current, not against it.
• Raise an arm to signal for help

Accident List

The tragic and recent death of an OIST student whilst spending recreational time in the sea highlights all too clearly the potential hazards of water related activities in Okinawa. If you are spending time at the coast or in the sea whether recreationally or as part of field work activities, please be aware of the hazards. There are particular spots around Okinawa that are known to have strong currents. Sadly, there have been many ocean related accidents reported across Okinawa in the last year. See below

Be aware of the hazards when going to the field. Popular sites close to OIST also have hazards, such as Apogama and Maeda Misaki. Following is the list of accidents that were reported in Okinawa during 2021 and 2022.
