Aha surf guide

Aha is a surf spot that offers a mix of conditions for different skill levels. It's located around the port area and features a few waves that attract surfers looking for a decent session. The vibe here can be laid-back, but you should be prepared for some crowds, especially at the more popular breaks. The local scene can also be a bit touchy at times, particularly at Aha-yoko, which is known for its more challenging waves.

The surf at Aha generally works best on a low tide, delivering some easier right waves around the port. The lefts at Aha-yoko are different; they can be hollow and heavy, making them more suitable for expert surfers. The optimal swell direction is from the Northeast, though it also handles swell coming from both the North and East. You can expect the spot to work with swell sizes around 2ft (0.6m) and up, breaking over an uneven reef. The wave directions include both lefts and rights, which gives you a chance to pick your preference. For the best experience, aim for a West wind and try to hit it at low, mid, or high tide.

Keep in mind that Aha isn't for beginners, especially at Aha-yoko. You'll want to make sure you're confident in your skills if you venture there. The port area will be more forgiving, making it a better spot for improvers who are still building their skills. Just be aware of the crowd, as it can get busy, and respect the locals to have a smoother experience.
