The Lowdown
Alright, Rusty here again, breaking it down in feet and Fahrenheit for you land-based lot.
Let's be real about Aja: the next two weeks start with a long, dry spell. We're looking at a solid gap of nearly a fortnight before anything worth paddling out for shows up.
Your first chance to get wet is the morning of Friday, September 11th. We're talking a tiny wave, about 3 feet from the north, but the wind is light and clean offshore. It's surfable, but nothing to write home about. That little window shuts fast, and we're stuck with a week and a half of small, weak, messy surf. We'll see a few clean mornings with waves around 1 to 2 feet from the east, but the energy is pathetic – barely cracking 60 (60) on the combined scale. It's the kind of stretch that'll have you cleaning your board more than riding it.
The big news is the standout. Mark your calendar for Wednesday, September 23rd. The morning is the real deal. We've got a solid 4-foot groundswell from the east, packed with a long, powerful 13-second period. The combined energy is going to be pumping at 566 (566) – that's proper juice. The wind is looking like a light, clean offshore breeze from the ESE, which will have the reef running smooth as glass. Aja is an exposed spot, so it needs that; with this setup, it'll be offering clean, rippable walls. The water is a warm 83.6°F, about average for the season, so you'll be fine in a spring suit. The afternoon holds at about 3.6 feet from the east, but the morning is the winner. The crowds can get thick here sometimes, so beat the rush for the best waves.
So, a long wait for a short burst of quality. The morning of the 23rd is your one and only gold star. Stay patient.

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.
