Table - best surf conditions forecast for Yonabaru over the next 16 days.
Right then, let’s have a look at what’s on the cards for Yonabaru. It’s a beginner-friendly, fairly consistent beach setup that’s fairly exposed to the swell, but it gets a bit of a hiding when the wind turns nasty.
The next few days are a total write-off. A massive pulse of swell hits from the 9th of July, with waves jumping to 16ft by Thursday afternoon and a combined energy reading of 13101 – that’s serious power. But it’s accompanied by strong onshore winds and a risk of thunderstorms, so the ocean is just a messy, blown-out beast. Friday the 10th of July sees the swell peak at a monstrous 33ft out of the SE with an 18-second period and energy hitting 67919, but it’s paired with a near gale wind. That is far too big for this break and pure danger. Saturday and Sunday are still blown out with gale-force cross-onshore winds; there’s no surf to speak of for a beginner, or anyone sensible.
There’s a long, bleak gap with nothing rideable for over a week. Small, chopped-up leftovers and poor conditions dominate right through to the middle of the month. The water temperature sits at a warm 84°, with an anomaly of -0.2°, so pretty much normal for the time of year.
The first real glimmer comes on Sunday the 20th of July. The morning shows a clean, cross-offshore wind with 3ft of east swell, period 12 seconds, and a combined energy of 365. That’s a modest but clean wave with light winds – a quiet, uncrowded option. But the stand-out, the true gem in this whole forecast, is Monday the 20th of July afternoon. It’s glassy – dead calm wind from the WSW at just 3 mph – with 3ft of east swell at a 12-second period and energy of 421. For a beginner-friendly spot like Yonabaru, that’s about as good as it gets. Clean, fun-sized waves, light crowds (just “sometimes” there), and conditions that’ll put a smile on your face. This is the best on offer.
After that, Tuesday the 21st of July sees a bump up to 6ft east swell with a 13-second period and energy of 1044, but the wind is a light cross-onshore, making it a bit messier. Still, it’s a solid swell for those keen on a paddle. The rest of the outlook fades again into small, chopped-up surf through to the 23rd. Keep your eyes on that glassy Monday afternoon – that’s the one.

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.
