Why did you swim against a rip current?

> normal to the rip tide

as an engineer, I assumed this ('normal') meant across/perpendicular/90 degrees to the rip tide, not against it ...

I believe 90 degrees to a rip tide is the correct thing to do ...

Yes, that's what they meant. Rip tides aren't usually that wide. The best thing to do if you get caught in one is to remain calm and swim perpendicular to the current.
