The Lowdown
Right then, let’s have a look at the surf outlook for Aja.
Honestly, for the next week and a half, it’s looking pretty flat. There’s barely a ripple until the 24th of July. We’ve got a real dry spell here. From today, the 15th, right through until the morning of Thursday the 24th, it’s mostly tiny waves with poor surf conditions. The swell is regularly under 1 ft with periods all over the shop, and the wind is mostly cross-shore, messing up any chance of a clean wave. The combined swell energy is often in the teens or low twenties, so it’s very weak. Don’t get your hopes up for this stretch; it’s a board-shiner.
The first real glimmer of hope comes on the morning of Thursday, the 24th. We’ll see a tiny 1 ft swell rolling in from the ENE with a period of 11 seconds. The combined energy climbs to 57 (moderate), and with a light southerly breeze keeping things clean, it’s surfable but very ordinary. Still, you could get a learner log out there.
The best bet of the whole 16-day window is the morning of Saturday, the 25th. The swell is still a modest 1 ft from the ENE, with a 10-second period. The combined energy is 51 (moderate). What makes it a standout is the 3 mph NE wind going glassy. That’s a rare treat. For a reef break, the glassy conditions will make it look beautiful, but don’t expect any power. Crowds are ‘sometimes’ possible here, so you might have a few friends out.
After that, it fades out. Sunday the 26th morning sees a 1.0 ft ENE swell with a 17-second period, but the wind turns cross-shore, killing the vibe. The rest of the run into the end of the month is either flat or just too windy. On the 28th and 29th, we get a strong offshore wind from the SE, but it’s blowing at 19 to 28 mph. That’s too strong for a paddle. The swell is tiny and the period is either missing or 12 seconds, so the wave energy is just a 25 (weak). That setup is far more interesting for kite surfing than paddle surfing. The water temperature is about average for the time of year.
So, to sum it up: you’ve got a long flat spell, then a couple of very ordinary days, with the glassy Saturday morning being the only real highlight. Keep an eye on the charts, but don’t rush to 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.
