The Lowdown

Alright folks, Rusty here. Let’s break down what the next couple of weeks look like for Aja.

To be honest, we’re staring at a pretty quiet and frustrating stretch for a while. The first few days are a total washout with messy cross-shore winds and only tiny, weak swell. Don’t bother paddling out until the 5th of September. That Saturday morning finally brings a pulse of waist-high, north-northwest swell, about 2ft, with a 10-second period. The wind swings cross-offshore and the water’s clean, which is a big relief. The combined energy is still only moderate at 136, so it’s not gonna be pumping, but it’s rideable. That afternoon stays clean with a light breeze, same sort of size. It’s the best we’ve got in the first week, but it’s really just a small, ordinary session.

The weekend after that turns nasty again. Sunday and Monday get blown out by strong onshore and cross-onshore winds, with lumpy, choppy conditions and a rising but poor-quality swell. The energy climbs into the 170s–180s, but it’s short-period windswell and the wind is ruining it. For a reef like Aja, this is more of a kite-surfing kind of setup than a paddle session.

Midweek doesn’t help much either. The waves are small and weak, with the cross-onshore winds still making a mess of things. The 8th and 9th of September have some longer-period energy (12 seconds on Tuesday morning), but the wind is straight onshore and all that energy is wasted. The combined energy hits 249 that morning, but it’s not surfable.

The real hope comes from the second week. Around the 14th and 15th of September, we get a decent little run of easterly swell. Monday afternoon the 14th sees clean, cross-offshore winds with 4ft of east swell, period around 9 seconds, and combined energy up at 271. The water will be about average temperature for this time of year. That’s genuinely good surf for Aja, clean and with some push. Tuesday morning the 15th looks even better: 5ft east swell, light offshore wind, clean conditions, and the energy jumps to 369. That’s the standout of the whole forecast. The swell direction is dead on from the east, which is the optimum direction for this break, so Aja should be lining up nicely. Keep in mind, this break is inconsistent and can get crowded sometimes, so get out early if you can.

After that, it fades off fast. The 16th and 17th have tiny, knee-high waves with glassy conditions on the 16th afternoon, but it’s not worth a special trip. The very end of the period, the 18th and 19th, stays small and clean but weak.

So, bottom line: the best windows are Saturday the 5th for a small, clean session, and then the real highlight is Monday the 14th afternoon through Tuesday the 15th morning. That’s your sweet spot.

Rusty.

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.

Aja is 4 km (2 miles) from the city of Tomigusuku. If you plan a holiday in Okinawa, look for hotels and other accommodation in Tomigusuku. Tomigusuku has rooms for a wide range of budgets as well as car hire and transport links.
