The Lowdown

Alright, Rusty here. Let’s talk about Aja. It’s a reef setup, and it’s inconsistent, so when it’s on, it’s a treat, but you’ll be waiting for it.

Right now, for the first couple of days, there’s a bit of swell around but the wind is just wrecking it. You’ve got a 7ft swell from the WNW on Wednesday the 26th, but that cross-off wind from the SSW is blowing at 25 mph, making it proper messy. The water’s sitting at 84°F, which is pretty much bang on average for this time of year, so no surprises there.

We get a bit of a cleanup on Friday the 28th morning. The swell drops to 4ft from the west, but the wind swings SE and goes offshore. That’s clean. The period is 10 seconds, so it’s got a bit of push. The combined energy is sitting at 264 (moderate), but it’s marginal. It’s a small window, not a stand-out.

Then from Saturday the 29th through to the end of the month, it’s flat or useless. Tiny waves, no energy, and the wind is all over the place. There’s a real gap here. Nothing worth paddling out for.

Into the first week of September, the swell picks up, but the wind is horrendous. On Wednesday the 2nd, the swell jumps to 21ft from the north with a period of 9 seconds, but the wind is onshore from the NW at 15 mph. The combined energy is a massive 6503 (very strong), but the conditions are just poor. That’s more of a kite-surfing setup than a paddle surf one. Too big and blown out for most.

The next real chance comes on Sunday the 6th of September morning. There’s a 10ft swell from the east, period of 10 seconds, but the wind is cross-shore from the NE at 19 mph, making it lumpy. The energy is strong at 1775 (very strong), but it’s still marginal. Not clean enough to call a stand-out.

The last hope in the window is Thursday the 10th of September afternoon. You’ve got a 10ft swell from the WNW, with a period of 8 seconds and a moderate breeze from the SSW at 15 mph, which is cross-off. The energy is 1615 (strong). It’s still only marginal, but it’s the best looking of the bunch. The wind is offshore enough to clean it up a bit. That’s your pick of the 16 days, but it’s a big, short-period swell, so it’s going to be heavy and for experts only. Don’t send the beginners out there.

So, to sum it up: the first week is a write-off, and the second week has size but is mostly messy. The standout, if you’re an experienced surfer, is the afternoon of Thursday the 10th of September. Keep an eye on it, but don’t get your hopes too high.

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.
