The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Aja over this 16-day stretch. I gotta be straight with you, it’s mostly a quiet period. The first good session doesn’t even show up until Saturday the 12th of September, so we’ve got a solid week of nothing worthwhile to sit through before then.

For the first week, don’t bother paddling out. The wind is mostly cross to cross-onshore, and the swell is small and weak. On Saturday the 5th, the swell reaches 5 ft out of the NW, but with a 19 mph cross wind, it’s just lumpy and messy. A couple of afternoons, like Saturday the 5th and Monday the 14th, try to offer something just over knee-high, but the conditions are ordinary. There’s nothing to get excited about here.

Now, we finally get a little hope starting Saturday the 12th. The swell drops to just 1 ft, but check it – that’s a clean, long-period groundswell coming from the east with a period of 14 seconds. Combined swell energy is low, around 86, but the wind goes light and cross-offshore, making for clean, glassy conditions. It’s tiny, but if you’ve got a longboard, the morning of the 12th might give you a few soft, peelers. The water temp is about average for this time of year, nothing unusual.

That little pulse hangs in through Sunday the 13th too, with a similar 2 ft east swell, 14 seconds, and clean cross-off breezes. Still not big, but it’s the cleanest run we get.

The best chance for something with a bit more punch comes on Monday the 14th of September. The morning sees the swell bump up to 4 ft from the east, period 7 seconds, and the combined energy hits 278 – moderate energy finally. The wind is a clean cross-off, so the surface will be smooth. It’s not a huge day, and the short period means it’ll be a bit crumbly, but for Aja, this is the standout. If you can get out on the Monday morning, that’s your window. The afternoon gets a touch bigger at 5 ft, but the quality is poor, so stick to the morning.

After that, it fades away again. Tuesday the 15th is flat, and the rest of the second week stays tiny, with 2 ft or less, and a few weak days of 1.0 ft by the 19th and 20th. The morning of Sunday the 20th of September is dead flat and glassy, but there’s no swell to ride.

Overall, don’t hold your breath for the first week. The only real shout is Saturday the 12th through Monday the 14th, with Monday morning being the pick of the bunch. Keep the expectations low, but the windows are clean.

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.
