Questions

What does a green flag mean in Ocean City?

Green flags signal lower relative hazard when Beach Patrol is on duty—not a guarantee of zero risk. Rips, shore break, and marine life can still appear.

Supervise kids, note your tower number, and keep flotation for weak swimmers. Recheck flags after lunch; colors change with wind and tide.

Yellow flag swimming limits?

Yellow urges caution—moderate surf or currents may be present. Weak swimmers and children should stay in shallow water and avoid floating far from guards.

Single red flag rules?

Single red restricts swimming to knee depth—no diving, no body surfing beyond shallow wading. Many rescues happen when visitors treat red like yellow.

Double red flag meaning?

Double red means the ocean is closed to swimming in Ocean City’s guarded system. Stay out of the water completely—no “just to the knees” exceptions when stands post double red.

Use Boardwalk, bayfront, or indoor plans instead. Conditions can improve later; only re-enter when flags and lifeguards allow.

Backup ideas: rainy day ideas and Beach Weather for timing the next window.

Purple flag marine life advisories?

Purple warns of dangerous marine life such as jellyfish blooms or occasional shark sightings—confirm with guards whether swimming is limited or only caution is advised.

Rip current parallel swim rule?

If caught in a rip, do not swim straight toward shore—swim parallel to the beach until out of the channel, then angle back in. Float to conserve energy if needed.

Is undertow the same as a rip current?

Undertow is a loose popular term—lifeguards and NOAA use rip-current guidance. Learn the parallel escape rule rather than outdated undertow myths.

Why are rips worse after storms?

Storm surf cuts new channels through sandbars—guards reposition flags after weather passes. Ask about fresh rips before swimming the morning after a rough night.
