Alright, let’s take this straight to feet and degrees, because that’s how we size it up.
The next couple of weeks at Aja look lean – real lean. We’re talking a long stretch with next to no surf worth paddling for. The first week and a half is pretty much a dead loss. Tiny, weak swell with lousy wind. The combined swell energy hangs out in the low single digits or flat zero for days. From Friday July 3rd right into the middle of the month, you’re looking at ankle-biters that never get above a foot. The wind is mostly cross or cross-off, so forget about a clean wave. The water’s about 2° cooler than average for this time of year, so it’s a touch chilly – nothing wild, but you’ll notice it.
The only day that shows any pulse is Friday July 17th. That one kicks up to 8ft from the east, with a long 15-second interval – proper groundswell. The combined energy goes ballistic, hitting 2982. The wind is strong offshore out of the south, so the surface will be clean and glassy. But at that size on a reef, you better be on your game. That’s expert territory. The long period will mean the waves are thick, lined up, and packing a punch, though the lulls between sets can be long.
The day after, Saturday the 18th, settles down to about 2ft from the east, still with clean cross-off winds. The energy drops to 173 – far more manageable – but by the afternoon it fades out again.
So, the one real standout is that Friday the 17th. It’s the only proper swell of the whole run, and the wind is in its favor. But it’s a long wait and a big, heavy wave when it arrives. For now, the rest of the forecast is quiet. Things can change, but if you’re looking to get wet, you’ve got some time to kill.

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.
