The Lowdown

Alright folks, Rusty here, and I’ve been staring at the charts for our little stretch of coast at Aja. Gotta be straight with you—this is a tough one. We’re looking at a 16-day window, and honestly, for the first half of it, we’re in a flat spell. For a solid week from the start of the forecast, there’s just nothing doing. The swell is tiny and the wind is cross-off or cross, which gives clean conditions, but on waves of 1ft to 2ft, it’s board-float territory.

Even when Sunday the 13th afternoon shows a bump up to 4ft from the East, it’s a short-period 6-second windswell with moderate energy (169) and the wind is cross-off. Still poor surf conditions. It’s not really giving us anything to work with.

Around the middle of the period, things get more interesting but also dangerous. By Sunday the 20th, the wind starts ramping up. Sunday afternoon we see a serious jump: 12ft swell from the East, but it’s a 16-second period groundswell. That’s a proper long-period groundswell, and for a reef setup like Aja that’s exposed, it should create some powerful lines. The combined energy is strong at 6289. But—and it’s a big but—the wind is a near gale cross-onshore at 31 mph, with a risk of thunderstorms. It’ll be blown out and messy.

Then Monday the 21st is just plain violent. The wind is a violent storm force, 65 mph gusting from the North to NNW. The swell is still big, up to 10ft from the East with a long 14-second period, and energy is 4534 in the morning. This is expert-only territory for size, and with hurricane-force winds, it’s a total mess. Not for paddling.

After the storm passes, Wednesday the 23rd shows some relief. Morning sees a 4ft swell from the North, with a 10-second period and moderate energy (405). The wind is onshore at 19 mph though, so it’s not pristine but the danger is gone.

In the second week, it all just fades back to flat. By the 25th onwards, we’re back down to 0.7ft to 2ft with glassy conditions on the 27th morning. Clean but tiny.

If you’re a beginner, the whole period is a write-off. Even the smallest days are right at the boundary of surfable. For experts, the big storm swell is too dangerous with the wind. The whole setup looks more interesting for kite surfing than paddle surfing on those wild days.

Look, we’re in a bit of a flat run here. It happens. Forecasts change.

Stay safe, keep the board waxed. 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.
