Alright, Rusty here again. Let’s break down what’s cooking at Ada, but in feet and miles per hour this time.
We’ve got a slow start, but the real standout is coming up early. The first session worth paddling for is Tuesday morning, July 7th. Monday afternoon offers tiny waves about 2ft, glassy, but just not enough juice. Tuesday morning though – that’s the one. Ada has clean 4ft swell out of the ESE, a very long 14-second period, and glassy winds. Water temp is 28°, which is about average. The combined swell energy is moderate (578), but the conditions are premium – long, clean lines, consistent, and crowds are possible at this reef spot.
Tuesday afternoon stays fun with a light cross-shore. Then Wednesday morning, July 8th, the swell hits 8ft from the ESE with a 16-second period. That’s a lot of power (2787 energy), but the wind is cross-onshore and choppy, so the quality drops. By the afternoon, it’s 8ft and even rougher – only for experts and not firing great.
From Thursday, July 9th, the forecast turns nasty. Swell builds to 13ft with strong onshore winds (22-25 mph) and thunderstorms. Combined energy hits 7539 and 9308 – massive, but blown to bits. Friday and Saturday are a write-off with near-gale winds over 30 mph and no rideable swell recorded. This big, messy stretch runs through July 13th.
After that, swell drops to tiny 1ft to 3ft waves through the middle of the month, but the wind stays messy – mostly cross-onshore or cross, moderate breezes, occasional thunderstorms. The only minor bright spot is Saturday morning, July 18th, with 3ft from the ENE, a clean cross-offshore breeze, and an 11-second period. It’s small, with just 158 energy, but at least it’s clean.
The last bump of 6ft shows up Monday, July 20th, but with fresh onshore winds, it’s no good.
So, in a nutshell: Tuesday morning, July 7th, is your only proper window. After that, it’s either too blown out or too small. Lock in that date for the best of the run.
Rusty.

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.
