Hi Nix, I was there in May.
Was one of my favourite places, surf, food, the people - just awesome!
I suggest you brush up on a few Basque phrases, goes a long way!
I hired from Pukas surf shop on the strip opposite the beach as well as the surf school that runs out a dugout on the beach towards the west side of the beach. The exact rates escape me but from memory was not too over the top, I needed to hire a wetty cos it was icecream headache cold, imagine would be colder now.
If you are there for a while might be beneficial to buy a second hand board then flog it off before you go?
Good beachy that picks up a lot of swell, I scored waves everyday I was there
