# AI advises swimming parallel to the shore to escape a rip current (incorrect direction and exhaustion risk)

## Root Cause

Rip currents are narrow, fast-moving channels that flow perpendicular to the shore; swimming parallel may keep the swimmer in the current if they are in the center, and the direction of escape depends on the current's exact location and shape.

## Workarounds

1. **If caught in a rip current, float or tread water to conserve energy. Do not panic. Signal for help by waving your arm.** (90% success)

2. **Swim parallel to the shore in the direction of the longshore current (the direction the waves are breaking), not directly against the rip current. Once out of the current, swim at an angle back to shore.** (85% success)

## Dead Ends

- **Swimming parallel to the shore in the direction of the current flow** — If the swimmer is in the center of the rip current, swimming parallel may not exit the current; the current can be 10-50 meters wide, and the swimmer may tire before exiting (80% fail)
- **Swimming parallel in the opposite direction of the current flow** — This can push the swimmer into the current's strongest part and cause exhaustion; the direction of the rip current is not always obvious (70% fail)
- **Trying to swim directly back to shore against the current** — This is the most common fatal mistake; the rip current is stronger than the swimmer, and exhaustion leads to drowning (95% fail)
