The Lowdown
G'day, Rusty here. Well, to be honest, the next week or so is looking pretty grim for a paddle at Aja. We’ve got a solid run of no surf or super tiny, weak stuff with poor conditions right through until the end of the first week of August. The wind is mostly onshore or cross-onshore, keeping things messy. There’s a few days with tiny 0.7ft to 2ft waves, but the period is short and the energy is just a whisper (values between 5 and 19). Honestly, it’s a write-off for a while.
The first bit of real hope shows up on Thursday, the 6th of August. The swell jumps to 8ft from the east, with a very long 17-second period, and the combined energy goes through the roof (3194). That’s serious groundswell energy. But, and it’s a big but, the wind is a light cross-shore on the morning and then cross-onshore in the arvo. The forecast notes say “marginal surf forecast or questionable tide conditions,” so it’s not a guarantee. At that size and period, Aja (a reef break) could be a proper beast, and with this much energy, it’s going to be a heavy drop. This is expert territory only. The morning might be the cleaner window, but it’s still a gamble.
Friday the 7th and Saturday the 8th of August see the swell hold at a solid 10ft from the east, with that same long 18-second period. The energy is massive (4762 to 7336). The wind is cross-onshore, though, so it’s going to be bumpy. The morning of Saturday the 8th rates a 5/10 internally, so it’s the best of a rough bunch, but still likely choppy. This is big, powerful, and not for the faint-hearted.
The real standout, the one that makes my heart beat a little faster, is Monday the 10th of August. The swell drops a touch to 7ft from the north-northeast, with a long 14-second period, and the energy is still huge at 3692. But the wind is light and cross-offshore from the east-southeast. That’s clean. The forecast calls it “excellent surf conditions for experienced surfers.” That’s the call. It’s still a big wave for a reef, so beginners need to stay on the beach, but for the crew who know what they’re doing, this is the session to circle. The crowd is a factor here though – Aja can get crowded sometimes, so get in early.
Tuesday the 11th of August keeps the quality going. The swell eases to 6ft from the northwest, still with a 12-second period, and the wind is offshore from the southeast. Clean again. The energy is still strong (1332). It’s a touch smaller, which might make it a bit more manageable, but still a proper wave for the experienced surfer.
The water temp is sitting at 85°F, which is a whopping 0.5°F warmer than usual for this time of year. Pretty average, nothing to write home about.
So, the long and short of it: the first week is a total bust. The real action kicks off on the 6th, but it’s big and bumpy. The absolute best of the run is that Monday the 10th and Tuesday the 11th, with clean, offshore winds and solid, long-period swell. That’s your window.
Stay safe, and I’ll see you in the water.

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.
