One of the few surf stores that stocks rentals, Hot Coast is conveniently close to the best surf spot in Ipanema, Arpoador beach. It's open Monday through Saturday only, so you'll need to book ahead if you want to surf over the weekend. Rentals range from R$20 to R$40 (US$8.40-US$17/£4.20-£8.50) for a short board, fun board, or long board.
