Table - best surf conditions forecast for Ada over the next 16 days.
G’day, it’s Rusty here. Let’s be straight – this is a tough one for Ada. The whole 16-day window is pretty much a write-off for decent surf. There’s a massive pulse of swell coming through, but it’s way too much for the break, and the wind is a nightmare for most of the run. The water temp is sitting at 83°, which is about average for this time of year, so no surprises there.
The first real event kicks off on Thursday, July 10, but it’s ugly. The swell is pumping – 23ft from the SE with a 18-second period, giving a combined energy of 28182, which is very strong. But the wind is a howling easterly at 34 mph, straight onshore. It’s a gale-force mess. The wave comment says the swell is too big for this break, and I’d agree. This is strictly for experts only, and even then, it’s a battle. The wind stays onshore and strong through Friday, with swell up to 25ft and energy hitting 35911. It’s a stormy, dangerous situation.
Then from Saturday, July 11, through to Wednesday, July 15, the swell drops right off, but the wind is all over the place – cross-onshore and cross-shore, with a lot of stormy weather. The surf is tiny, mostly under 2ft, and the energy is weak (mostly under 100). The best window in that stretch is Wednesday morning, July 15, when the wind goes glassy with a light WNW breeze, but the swell is only 1ft with a 9-second period and energy of 28 – it’s flat, really. There’s nothing to ride.
The second week doesn’t offer much either. From Thursday, July 16, to Friday, July 24, there are a few pulses of swell, but the wind is persistently onshore or cross-onshore, and the break is exposed. On Sunday, July 19, there’s a 3ft E swell with a 13-second period, giving energy of 212 (moderate), but the wind is cross-shore from the south at 12 mph, which chops it up. The best-looking day is Tuesday, July 21, with a 8ft ENE swell, 14-second period, and energy of 2763, but the wind is onshore at 16 mph again. That’s too big for the break and the wind is poor. By Friday, July 24, the wind goes cross-offshore from the SSW at 19 mph, but the swell is tiny at 3ft with a short 7-second period and energy of just 94. It’s clean but weak.
Overall, there’s no standout day here. The consistent theme is either too much swell with bad wind, or too little swell with messy conditions. The break is fairly consistent, so it’s a bit of a shocker to see such a blank run, but it happens. Keep an eye on the forecasts – things can change.

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.
