Couple outside on Saturday like the beach (5)

I believe the answer is:

sandy

I'm a little stuck... Click here to teach me more about this clue!

'like the beach' is the definition.
(I've seen this in another clue)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for sandy that I've seen before include "Like many beaches" , "Ginger" , "Hair colour" , "Light yellowish brown" , "Alexander (shortened)" .)

I've seen this clue in The Times.
