The Lowdown

Righto, let’s have a look at what’s on offer at Aja. This is a reef break, and it’s an inconsistent one, so when we get a window, it’s a rare treat. Straight off the bat, the water temp is sitting about average for the time of year.

The next week and a half is pretty grim, to be honest. There’s a bit of small, weak swell from the 30th of August through the 1st of September, but the wave energy is tiny (45) and the conditions are just poor. We’ve got a moderate offshore breeze on Sunday morning, but the swell is only 1ft and short on energy. It’s a real struggle.

We finally see a spike on Wednesday the 2nd of September. The morning brings a solid 6ft swell from the east with a 9-second period, and the combined wave energy jumps right up to 465 (moderate). The wind is offshore from the southeast, so it’ll be clean. That’s the best the first week has to offer. But don’t get too excited; the afternoon drops off drastically, and the following days are all small, weak, and mostly blown out by fresh cross-shore winds. The 6th and 7th of September see the swell pick up again, but the wind is howling onshore or cross-shore, turning it into a messy, choppy mess. For a beach setup, that wind and swell would be more interesting for kite surfing than a paddle session.

Now, for the real standout. On Friday the 11th of September, there’s a window of perfection. We get a clean 8ft northeast swell with a short 8-second period. The wind is a light easterly breeze, glassing it up. The wave energy is strong at 751. This is the one to circle. It’s a reef break, so the short period will help the waves stand up nicely. The only catch is the size: at 8ft, this is expert territory. For the intermediate surfer, it’s going to be a handful.

The day after, the 12th, is a write-off with a massive 25ft swell and onshore wind. That’s for big-wave chargers only, but the wind is wrong for it here.

So, to sum it up: the first ten days are mostly flat and poor. The real standout is the morning of Friday the 11th of September at Aja. It’ll be clean, powerful, and solid, but it’s strictly for crew who can handle a heavy 8ft reef break. The rest of the window fades into small, messy swell and onshore winds.

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.
