The Lowdown

Alright mate, Rusty here. Let’s have a look at what’s on the cards for us. To be straight with you, the next couple of weeks are looking pretty grim for a proper paddle. The only break that’s got any kind of nod is Yonabaru, and it’s a real rollercoaster ride. The water temp is sitting at 84°F, which is bang on normal for this time of year, so at least you won’t need a thick wetsuit.

The first real standout pops up on Wednesday, 26th August. The ocean is going to be absolutely pumping with a massive 12 ft to 13 ft swell from the ESE, and the energy is through the roof (6168 to 7565). The wind is going to be a clean cross-off, which is a huge bonus. But here’s the thing – this is way too big for anyone but a seasoned expert. The swell period is super long, around 16 to 17 seconds, which means it’s a proper groundswell with heaps of power. At a fairly exposed spot like this, that’s going to be a serious, heavy, and probably pretty intimidating wave. Beginners, stay well clear.

The next window that’s worth a look is the 27th of August. It’s still a big swell, coming down to 8 ft to 10 ft from the E, with a fresh offshore wind from the WNW. That’s clean, make no mistake. The energy is still strong (3624 to 4604), but the conditions are a bit marginal. It’s a big, powerful wave, but it’s not the best shape. Still, for the experienced crew, it’ll be a fun paddle out.

After that, the 28th of August sees the swell drop to a more manageable 5 ft to 7 ft. The wind is light offshore from the W and WNW, so the face will be clean. The energy is moderate (518 to 832), and for a spot that’s fairly consistent, this is the best all-rounder in the whole forecast. It’s not a monster, but it’s a solid, clean wave that’ll be fun for a wide range of surfers. This is the pick of the bunch for most of us.

The rest of the run is a bit of a bust. There’s a big gap of no surf from the 29th of August through to the 2nd of September. The waves are tiny or non-existent, and the wind is all over the place. The 3rd of September shows a bit of a pulse with an 8 ft NW swell, but the period is short (7 to 8 seconds), and the wind is a cross-shore, making it messy and choppy. Not a great option.

So, to wrap it up: if you’re an expert with a death wish, the 26th of August is your day. For everyone else, the 28th of August is the one to circle. It’s clean, it’s got some push, and the vibe will be good. The rest, well, it’s a waiting game.

Rusty.

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.
