The Lowdown
Alright, Rusty here. Let’s break it down.
First up, it’s a flat spell for the next week and a half at Yonabaru. From Wednesday the 22nd through the end of July, there’s basically nothing. Swell heights are tiny at 0.3 to 0.4 feet, with a short period around 9 to 10 seconds, and the combined wave energy is weak (between 14 and 54). Winds are mostly onshore or cross-onshore, so it’s choppy and messy. Water temp is 83°F, which is about normal for this time of year. A solid ten-day stretch of no surf.
Things finally perk up on Saturday the 1st of August. The morning shows a small bump of 0.5 feet from the east, but the real change comes that afternoon. Swell jumps to 0.7 feet out of the east-southeast, with a long period of 16 seconds – that’s real groundswell. The wind goes cross-offshore from the southwest, cleaning it up. Wave energy is moderate (305). It’s small, but it’s a start after a long dry run.
The real standout is Sunday the 2nd and Monday the 3rd of August. Sunday morning is glassy with a light westerly breeze. Swell is 1 feet from the east, with a very long period of 17 seconds. That’s proper groundswell with some punch. The combined energy is strong (696). This is set to be clean and rideable. By Sunday afternoon, the swell pushes to 1 feet, and energy hits 920. This is the best bet for the weekend. Monday morning sees the swell at 2 feet, still from the east with a 17-second period, and cross-offshore winds from the north-northwest. Energy is very strong (1298). Monday afternoon is the peak: 2 feet, 18-second period, and clean offshore winds. This is excellent for experienced surfers, with energy at 1611. Keep in mind, the long period means longer waits between sets, but the waves will be powerful.
Tuesday the 4th of August gets rough. The morning shows a solid 3 feet from the east-southeast, but the wind is cross-shore with thunderstorms. Energy is massive (7029), but it’s messy and heavy – only for experts. The afternoon drops to 2 feet, but the wind goes cross-onshore, making it choppy. After that, the swell fades through the week with onshore winds, and by Thursday the 6th, it’s back to poor conditions.
So, the real call is Sunday the 2nd and Monday the 3rd. Hit the Sunday morning glass for the cleanest, most user-friendly waves, or Monday afternoon for the biggest, cleanest, and most powerful swell of the run. Yonabaru is a beginner spot, so when it hits 2 to 2 feet, it’s pushing into more challenging territory. Crowds are sometimes a factor, so expect company.
Rusty out.

Information about the Yonabaru Surf forecast
The above surf forecast table for Yonabaru provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Yonabaru can be found by selecting the local surf guide option on the grey menu. Our Yonabaru 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 (Yonabaru) 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 Yonabaru 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.
Yonabaru is 5 km (3 miles) from the city of Ginowan. If you plan a holiday in Okinawa, look for hotels and other accommodation in Ginowan. Ginowan has rooms for a wide range of budgets as well as car hire and transport links.
