The Lowdown
Alright, Rusty here, let’s talk about what’s happening at Aja.
First off, the bad news: we’re looking at a real dry spell right now. From Wednesday, the 22nd of July, right through to the end of the month, there’s just nothing doing. The waves are tiny, the energy is weak, and the reports are all “poor surf conditions.” A few days there’s no swell at all. It’s a flat spell that lasts about a week and a half. You’d be wasting your time paddling out.
But then, come Sunday, the 2nd of August, things change. That morning, the wind goes glassy from the west at just 5 km/h, and we’ve got a 4 ft groundswell rolling in from the east with a very long period of 17 seconds. The combined energy jumps to 675 (moderate), and the water temp is 83°F, which is about normal for this time of year. That afternoon, the swell bumps up to 4 ft, energy hits 869, and the wind stays glassy. The report says “expect very good surf conditions.” This is a genuine standout. Aja is a reef break, so that long period, easterly groundswell will wrap in nicely. Clean, glassy, and solid. It’s the best on offer, no question.
Monday the 3rd of August sees the swell pulse up to 5 ft in the morning, period still 17 seconds, and energy jumps to 1298 (strong). But the wind turns onshore from the NNW at 10 km/h, and the report says marginal conditions. That afternoon, it’s 5 ft swell with a 18-second period, energy 1579, but wind is cross-onshore. For a reef, that’s not ideal. It’s still got power, but it’s not clean.
Tuesday the 4th of August gets bigger – 7 ft in the morning – but with a 20 km/h wind from the north, it’s cross-onshore and choppy. Energy is 2373 (very strong), but that’s messy. Not for the faint-hearted. The afternoon drops to 5 ft, but the wind is cross-shore, creating cross-chop.
Then Wednesday the 5th of August is another good shout. The swell drops to 4 ft, still a long 16-second period from the east, but the wind is light cross-offshore from the ENE at 10 km/h. Energy is 687 (moderate). The report says “very good surf conditions.” Clean again. Thursday the 6th of August eases further to 3 ft, period 14 seconds, with light offshore wind. Good, but smaller.
So, the highlight is Sunday the 2nd of August, with that glassy morning and 4 ft of clean, long-period groundswell. Wednesday the 5th of August is the backup with clean, smaller waves. The rest of the window is a write-off until that little pulse.
Stay patient, and keep an eye on the long-range – that Sunday swell is the one to circle on the calendar.
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.
