Question?

Dip akıntısını nasıl anlayabilirim ?

@okan-yalçın What exactly do you mean? Can you please provide further info?

@Suty thank you
(doğu batı yönleri örnek olarak veriyorum
Deniz üzerindeki dalganın batıya, deniz altındaki akıntı yönünün doğuya yöneldiği durumu.
Program üzerinden anlayabilir miyim ?
Yani asıl öğrenmek istediğim denizin altındaki akıntı yönü neresi?)I give the east-west directions as an example
A situation where the wave over the sea is directed to the west and the direction of the current under the sea is directed to the east.
Can I understand it through the program?
I mean, what I really want to learn is where is the direction of the current under the sea? -
rip current (ölü dalga, geri çekilme dalgası)

“Rip current is a relatively strong, narrow current flowing outward from the beach through the surf zone and presenting a hazard to swimmers.”
This is a very local phenomenon. The resolution of the Current and Waves data source is too low to directly display this type of current on a beach.
See more about rip currents:
https://www.weather.gov/safety/ripcurrent-science#:~:text=It is not possible to,by which hydrodynamic rips form.
The probability of rip currents seems to be higher with taller waves and longer wave period and during low tide between 2 half tides.
It does mean there is no risk out of these conditions.

hi @idefix37
thank you very much for this excellent explanation. There is also something I would like to ask.
The direction of the waves like in this picture,
Does the swell direction matter?

@okan-yalçın
According to this site, swell direction is not a determining factor.

The occurrence of rip currents seems to be relatively unrelated to direction, but this study was only conducted at one beach. At other sites, direction may be more significant?
Another interesting and comprehensive paper

Thank you for informing me. I will probably take the boat out and fish by trial and error from now on.
Because it is very difficult to fish when there is rip current.
