Alright, let’s get real about what’s happening at Yonabaru for the next couple of weeks. Honestly, it’s a pretty patchy run for a while, so we gotta sit tight for the good stuff.

Right now, we’re looking at tiny, lackluster surf with mixed-up winds. Saturday and Sunday (July 4th and 5th) are basically a write-off – we’re talking ankle-snappers at best, with swell around 1ft to 2ft and a short, weak period. The water’s sitting at 81°, which feels a bit colder than usual for this time of year. Not ideal.

Monday the 6th sees a slight improvement with a little more energy, but the waves are still small and pretty ordinary. You could probably get wet, but it’s nothing to get excited about.

Now, here’s where things get interesting. Tuesday the 7th is the standout in this whole outlook. We’re looking at glassy conditions in the morning with the wind going light N and then turning glassy ENE in the afternoon. The swell builds to about 3ft in the morning, pushing up to around 5ft by afternoon, coming from the SE with a very long period of 14 to 18 seconds. This is proper groundswell, so expect clean, well-shaped waves with some decent power behind them. The swell direction (SE) is not exactly what Yonabaru is best setup for (NE is optimum), but with glassy conditions, the quality will still be on point. This is the day to paddle out.

After that, it’s a sharp turn. Wednesday the 8th brings a solid 10ft swell from the SE, but the wind swings cross-on from the NNE, making it choppy and messy. The energy is huge, but that wind kills it. This is more for kite surfers than paddle surfers. By Thursday and Friday (9th and 10th), conditions get downright dangerous with 15ft to 16ft swell, strong cross-onshore winds, and even thunderstorms. That’s a hard pass unless you’re on a gun and have a death wish. These are expert-only conditions at best.

The second week is a real bummer. From Saturday the 11th through to the end of the period, we’re looking at either flat spells or tiny, weak waves with onshore or cross-onshore winds. Swell rarely tops 2ft, and energy is consistently low. There’s nothing worth chasing here. The break is inconsistent, and the conditions just won’t line up.

So, to sum it up: your only real window is Tuesday the 7th – glassy, clean, long-period swell hitting around 5ft by the afternoon. That’s your best bet by a mile. The rest of the run is either too small, too windy, or too big and messy. Keep an eye on the forecast, but don’t hold your breath.

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.
