The Lowdown
Right then, let's have a look at what Ada's got on offer over the next couple of weeks. I gotta be straight with you, it's a bit of a rough patch ahead. The whole 16-day window is looking pretty bleak, with no real quality surf to get excited about. We're looking at a long stretch of poor conditions.
The first real chance of anything surfable doesn't show up until the 4th of September, and even then it's marginal. From now until then, it's a solid week-plus of nothing worth paddling out for.
For Ada (a reef break), the swell direction it really wants is from the NE, but most of what we're seeing is coming from the E or ESE, so it's just not lining up right.
Now, on the 4th of September, things finally shift. We get a 10ft to 12ft groundswell from the NNW, with a period of 10 to 11 seconds. The combined energy is strong to very strong, hitting 4235 and 3081. The wind goes offshore from the W and WNW, which is clean. However, the swell is big, over 8ft, so this is for experienced surfers only. And with a long-period groundswell like that at a reef break, it could be a bit tricky to get into.
Then on the 5th of September, we see a similar but slightly smaller swell, around 8ft to 8ft from the N, with a long period of 12 seconds. The wind stays cross-off from the WNW and NW, keeping it clean. The energy is still strong (2004 and 1735). Again, this is expert territory due to the size and the long period groundswell.
The water temperature is around 83°, which is about average for this time of year.
Honestly, for the first week and a bit, with the strong onshore winds and messy conditions, this looks more interesting for kite surfing than paddle surfing.

Information about the Ada Surf forecast
The above surf forecast table for Ada provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ada can be found by selecting the local surf guide option on the grey menu. Our Ada 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 (Ada) 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 Ada 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.
Ada is 34 km (21 miles) from the city of Okinawa. If you plan a holiday in Okinawa, look for hotels and other accommodation in Okinawa. Okinawa has rooms for a wide range of budgets as well as car hire and transport links.
