The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks at Aja.

Honestly, the outlook is pretty bleak for a while. We've got a long stretch of poor conditions before anything remotely rideable shows up. The first real chance for a wave comes much later in the period.

For the first week or so, from the start of September right through to around the 10th, it's a write-off. Strong onshores, thunderstorms, rain, and messy, choppy conditions dominate. The swell that does show is either weak or blown out by fresh winds. You'd be fighting a losing battle.

Things start to tidy up a little around Friday the 11th of September. We get a brief window with an offshore breeze from the ESE at 12 mph, cleaning up a small 3 ft swell from the north (period 9 seconds). The combined energy is weak at 169, and while the sets will be clean, the waves are pretty ordinary. It's a marginal surf at best, but at least you'd be paddling into clean, lined-up faces without getting sandblasted. It's an option, but a very tame one.

The next real standout—and the only one worth getting excited about—shapes up for Thursday the 17th of September, into Friday the 18th. This is the one to circle on the calendar. We see a proper pulse of long-period groundswell arriving from the east. Thursday afternoon brings a solid 7 ft east swell with a very long 14-second period, and Friday morning pushes that to 8 ft with a 13-second period. The combined wave energy is strong, hitting 1579 on Thursday afternoon and 1754 on Friday morning. This is serious, powerful water moving through.

Now, the caveat. Aja is a reef break that's exposed to northerly swells, and this east swell isn't its ideal direction. A long-period east groundswell like this can be tricky on a reef that isn't built for it, often breaking a little too straight or closing out. But with the winds turning light and cross-off from the NE and the conditions staying clean, it could still produce some excellent, grinding waves for experienced surfers. For beginners, forget it—8 ft on a reef with that much energy is a no-go zone for anyone who isn't solid. This is an expert-only window, and it looks like the best shot we'll get in this whole 16-day stretch.

This has been Rusty, signing off.

Information about the Aja Surf forecast

The above surf forecast table for Aja provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aja can be found by selecting the local surf guide option on the grey menu. Our Aja surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Aja) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Aja may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
