The Lowdown
Alright, Rusty here. Let’s break it down.
First up, the outlook for Aja – it’s a reef break, and it’s been a real struggle. We’re looking at a long dry spell right from the start. From Sunday, July 26th, all the way through the morning of Wednesday, August 5th, there’s basically nothing worth paddling out for. The energy is reading zero, and the swell just isn’t showing up. It’s a tough stretch, with a few glassy mornings but no waves to ride.
Now, late on Wednesday, August 5th, things start to stir. A solid east swell pushes in, 5 feet, with a very long period of 16 seconds. The combined energy jumps to 1149 – that’s moderate wave energy. The wind is onshore, though, so it’s not clean. The conditions are marginal, and with the period that long, Aja’s reef setup could be a bit straight, but it’s the first sign of life.
Thursday, August 6th, sees the swell building. Morning runs 6 feet east, 18-second period, energy at 1995, but it’s still onshore and messy. By the afternoon, it’s 7 feet, still east, 18 seconds, but the wind switches to a cross-onshore, making it choppy. This is big, powerful, and long-period groundswell – definitely for experienced surfers only, and the wind is a letdown.
The standout window is Friday, August 7th. That’s the one. Morning starts with a 8 feet east swell, 17-second period, and combined energy at 3152 – strong wave energy. The wind is light cross-offshore, and it cleans up beautifully. Conditions are excellent for experienced surfers. The afternoon gets even better: glassy conditions, same 8 feet swell, 3065 energy. This is the best of the whole forecast. The swell direction is east, and Aja’s optimum is north, so it’s not a perfect match, but the size, power, and clean wind make it a real standout. Crowds are possible here, so keep that in mind.
Saturday, August 8th, drops off a bit. The swell holds at 8 feet east, 16-second period, but the wind goes cross-shore in the morning and cross-onshore in the afternoon. Energy is still high, but the quality fades. Sunday, August 9th, sees the swell drop to 4 feet, with a strong cross-offshore wind from the south, but it’s windy and the energy is down to 801. Not great.
The water temperature at Aja is 85°F, which is 0.5°F above the long-term average – basically normal for this time of year.
So, to sum it up: the first week is a write-off. Friday, August 7th, is the absolute best call – big, clean, and powerful, but it’s for experts only. After that, it fades. If you’re a kite surfer, some of those windy, choppy days might look interesting, but for paddle surfing, it’s a short-lived window.
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.
