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

'rider of waves swelling a' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'way to south of african country' is the wordplay.
I cannot quite understand how this works, but
'way' could be 'rd' (short for road) and 'rd' is located in the answer.
'country' could be 'mali' (Mali is an example) and 'mali' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
