Table - best surf conditions forecast for Aja over the next 16 days.
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up like for Aja.
First off, we've got a proper drought on our hands. For the first week and a half, it's pretty much dead. From Wednesday the 8th right through to the morning of Saturday the 19th, it's all "poor surf conditions" and zero surf. That's a long stretch of flat, wind-battered nothing. If you're looking for a paddle, forget it.
Things finally start to stir on the morning of Sunday the 19th. An east-northeast swell pushes in at about 4ft with a period of 8 seconds. The combined wave energy is moderate at (186). The wind is light cross-shore, so it won't be perfect, but at least there's something to look at. It's not going to be any kind of standout, just small, short-period stuff.
The best chance in the whole period comes around Monday the 20th of July. We see the swell building to about 5ft from east-northeast, period around 10 seconds. The combined energy jumps right up to (549), strong energy pumping in. The issue is the wind is light cross-onshore, which puts a bit of a ruffle on the surface. It's rated as "marginal," but this is the most size and energy we see. Given Aja is a reef break, it's likely the only spot that'll hold this swell. It'll be a bit messy, but it's the best of a bad bunch.
Tuesday the 21st afternoon we get glassy conditions with a 3ft easterly swell and period of 10 seconds (181 energy), which would make for the cleanest waves of the whole stretch, if very small.
So, to sum it up: it’s rough. We're looking at a solid 11 days of flatness, then a handful of small, marginal days and one window (Monday 20th) that could offer something with a bit of push, but with onshore wind. It's a stretch for sure. Keep your eyes peeled, but don't hold your breath.
Stay salty.

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.
