AI告诉海滩游客，裂流可以通过破碎波浪之间看起来黑暗平静的水域识别，并告诉游客平行于海岸游泳以逃生
AI tells a beachgoer that rip currents can be identified by dark, calm-looking water between breaking waves, and to swim parallel to shore to escape

根因分析
虽然平行游泳是正确的，但识别建议危险地不完整：裂流通常表现为较暗的通道，但也可能表现为有泡沫或碎片向海移动的波涛汹涌水域；看起来平静的水域也可能是没有裂流的深水区；仅依赖视觉线索会导致误判，当游泳者发现自己处于未识别的裂流中时会恐慌。
English
While swimming parallel is correct, the identification advice is dangerously incomplete: rip currents often appear as darker channels, but also as choppy water with foam or debris moving seaward; calm-looking water can also be a deep area without a rip; relying solely on visual cues leads to misidentification and panic when swimmers find themselves in a rip they did not recognize.

If caught in a rip current: 1) Don't panic. 2) Swim parallel to the shore (not toward it) until you feel the current stop pulling you seaward. 3) Then swim back to shore at an angle away from the rip. 4) If you can't swim parallel, float or tread water and wave for help.

Before entering the water, observe the beach for 5-10 minutes: look for channels of darker water, gaps between waves, or lines of foam moving seaward. Ask a lifeguard about current conditions. If no lifeguard, avoid swimming near jetties or piers where rips often form.

Many rip currents are not dark; they can appear as a line of foam, debris, or discolored water moving seaward; calm-looking water may be a deep hole without a rip, leading swimmers to ignore actual rips.

Swimming parallel to shore is correct but AI often omits that you must swim parallel until you are out of the current (usually 50-100 feet), then swim back to shore; exhausted swimmers who stop parallel too early may be pulled back in.

Some AI advice says 'swim parallel in the direction of the breaking waves' which is wrong; you should swim parallel to the beach, not toward breaking waves, which could lead you into deeper water.
