The Lowdown
Alright, let’s get into it. The next couple of weeks are a bit of a mess for Aja, honestly. The whole stretch is dominated by storms and chop, so we’re gonna have to pick our moments. The first real window of surf doesn’t even show up until later this week, and even then, it’s a battle.
First up, the wedge we get on Wednesday afternoon. We’re looking at a jump in size to 7.9ft, but the wind is going to be a cross-onshore NNE breeze at 19 mph, and the period is a short, weak 5 seconds. The combined energy is only 37, which is just weak. It’s gonna be lumpy and not worth the paddle. The swell direction is E, and the break’s optimum is N, so it’s just tapping in with the wrong angle.
Thursday brings a whole lot of water, but it’s a washing machine. The swell jumps to 14.8ft in the morning with a 18-second period, and the energy is getting serious at 11924. But the wind is a strong cross-onshore from the NNW at 28 mph, with a risk of thunderstorms. It’s just blown out. By the afternoon, it’s 16.4ft and the energy is at 16615, but the wind is a near gale from the NNW. It’s not a surf day, it’s a hold-onto-your-hat day. This is big for this reef, and not in a good way.
Friday is the same story, but turned up to eleven. The morning is a 26.2ft swell with a storm-force wind straight onshore at 62 mph. The afternoon is 34.4ft with 81 mph hurricane-force winds. The energy readings are off the charts, 28272 and 42745. This is a serious ocean, and it’s not for paddling. It’s a stay-on-the-beach and watch kind of day. The swell is way, way too big for this break.
By Saturday morning, the swell drops back to a more manageable 7.5ft, but the period has dropped to 11 seconds and the wind is still onshore from the WNW at 6 mph. The energy is 1630, which is moderate. It’s a marginal call, but the wind and tide are questionable. The afternoon is smaller, 4.3ft, and the wind swings to cross-shore from the SW, but the quality is still poor. The energy is down to 467. Not great.
Sunday, the wind goes absolutely wild again. The morning brings a 78 mph cross-offshore wind from the SSW, but the swell is flat. The afternoon is a 71 mph violent storm, but the surf is still flat. The energy is zero. It’s a completely blown-out day with nothing to ride.
Monday, we finally get a glimpse of something. The morning has a solid 13.1ft of west swell with a 14-second period, and the energy is up at 6740. The wind is a cross-offshore from the SSW, but it’s still a near gale at 37 mph. It’s clean, but it’s howling. The afternoon is a bit less wind, 28 mph, but the swell is down to 11.5ft and it’s still a marginal call. The energy is 4594. This is big and clean, but it’s a handful. Not for the faint-hearted.
Tuesday morning, the 11th, is the first real, proper window. The swell is 5.6ft from the west with an 11-second period, and the energy is 949. The wind is a moderate cross-offshore from the SSW at 16 mph. It’s clean, but it’s still only a marginal forecast. The afternoon drops off to 4.6ft and the wind goes cross-shore. It’s a one-morning window, and it’s not a standout.
After that, it’s a long, flat, weak stretch. The rest of the week and into the next, the swell is small, the periods are short, and the wind is onshore or cross-onshore. There’s a little window on the 12th with a 3ft wave and a light wind, but it’s ordinary. The 17th and 18th see a bit more energy, but the wind is going to be fresh to strong cross-onshore, and the swell is all from the east with a short period. It’s messy.
The best of the lot, if you can call it that, is that Tuesday morning on the 11th. It’s the only time the wind is truly offshore and the swell has a little bit of push to it. It’s not a classic, but it’s the cleanest window we get. The water temp is about average for this time of year, so nothing weird there.
The long-range stuff is a promise, but a distant one. The models are showing some east swell energy for the 19th, but it’s too far out to get excited about. The wind is looking cross-offshore in the morning, and the swell is 4.3ft with a 14-second period. That could be something, but it’s a long way off. For now, it’s a week of waiting and watching the wind.
There are no real standouts here, fellas. The ocean is just too angry for the first half, and then

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.
