The Lowdown

Alright, let’s get into it. The next sixteen days are a bit of a mixed bag for Aja. It’s a reef break, and it’s exposed, but man, it’s going to be a story of waiting for the chaos to settle.

Right off the bat, Thursday the 6th is a write-off. We’ve got fresh to strong cross-onshore winds and lumpy conditions. There’s swell, but it’s messy and ugly. The wave energy is weak-ish at under 200, so it’s not like there’s any power behind it to make up for the wind. You’d be fighting a losing battle. Friday the 7th is a different kind of problem. The swell pours in—huge, with the combined energy climbing to 22,905 and then an insane 32,649 in the afternoon. But the wind goes nuts too: a severe gale turning into hurricane-force. Even though the direction is offshore, that’s a hard pass. The swell is predicted to be way too big for this break, so it’s not a surfer’s day unless you’ve got a death wish.

The weekend is a mess. Saturday the 8th brings violent storm-force winds, and even though it’s clean, there’s no swell at all. A flat, blown-out kind of day. Sunday the 9th sees the storm ease a bit, but we’re left with tiny, weak swell—1ft to 2ft—and the energy is basically nothing (84 and 214). It’s clean, but there’s nothing to ride. Monday the 10th shows a spike in swell to 8ft from the west, but it’s still cross-offshore and the energy is moderate (2858). The morning is clean, but the conditions are still not great. The afternoon drops to 7ft and the energy fades a bit; it’s marginal. This is the most size we’ll see after the storm, but it’s not lining up right.

From Tuesday the 11th through the rest of the first week, it’s a slow decline. Swell drops from 4ft down to 2ft. The wind stays mostly cross or cross-off, and the energy is weak, mostly under 200. There are a few clean windows, like Wednesday the 12th morning with a gentle breeze, but it’s tiny at 2ft with a short period. Not really worth getting wet for.

We hit a rough patch from the 14th to the 17th. It’s small, weak, and the wind is often cross-onshore, making things choppy. The energy readings are mostly in the double digits. You might see chest-high waves at best, but the quality isn’t there. Aja is inconsistent, and this stretch really shows it.

Things pick up a touch on Tuesday the 18th. We get 4ft of swell, but the period drops to 6-7 seconds. That’s short-period windswell, which is going to be soft and crumbly. The energy is weak (165). It’s clean-ish with light cross-shore winds, but it’s not the kind of swell that makes a reef break like this shine.

The rest of the second week, from the 19th to the 21st, is more of the same: small, weak, and mostly messy. There’s a chance of a clean moment on Thursday the 20th afternoon with cross-offshore winds, but the swell is only 2ft. It’s not going to be epic.

So, to be straight with you, there’s not one standout day in this whole run for Aja. The biggest issue is that the big swell days are either blown out or too huge, and the clean days have no size. It’s a frustrating pattern.

Water temp is about average for this time of year, so no worries there for the first surf you might get. Honestly, if you’re itching for a paddle, the best bet might be early Tuesday the 18th, but don’t expect much. This is a period to fix your boards, not to score.

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.
