Alright, Rusty here again, talkin’ in feet and Fahrenheit now. This 16-day stretch at Yonabaru is a tough one. The break usually gets waves, but this forecast is a dud for the most part. We’ve got a big gap of no surf from Friday July 10th all the way through to Tuesday July 22nd – that’s nearly two weeks of nothing recommended.
First few days: Friday 10th to Sunday 12th – zero swell, strong winds, thunderstorms. Nothing. Monday 13th and Tuesday 14th bring a tiny 0.6–1.0 ft easterly swell with a 9-second period, but it’s cross‑onshore, choppy, and lumpy. Combined energy under 25 – pitiful.
Wednesday 15th and Thursday 16th still only 1.0 ft, but Thursday morning goes glassy – dead flat. Not worth a look.
Friday 17th sees a bump to 1.3 ft in the morning, then 2.6 ft by afternoon, but onshore wind kicks in. Energy hits 120 – still weak.
Saturday 18th is a mess. A 6.6 ft swell in the morning with a short 6-second period, strong cross‑onshore wind, energy 314. By afternoon it’s 13 ft with a severe gale – totally blown out. That’s expert size but unrideable. Sunday 19th through Tuesday 21st keep pumping 5.5–14.8 ft of easterly swell, but every session is onshore or cross‑onshore with fresh to strong winds. Energy values up to 4225 – huge power but zero quality. Kite surfers might get a look, but not for paddle surfing.
Wednesday 23rd finally offers something marginal. Morning: 5.9 ft easterly swell (10-second period) with a moderate cross‑shore breeze, energy 695. Afternoon: 7.2 ft, energy 922. Both are “marginal” – score 1 out of 10 – but the wind is not totally onshore. Still lumpy.
The best day is Thursday 24th. Morning: 3.3 ft easterly swell, 11-second period, light cross‑offshore breeze, clean. Energy 252 – moderate. Afternoon: 3.0 ft from the ESE,
Short Range ForecastHeavy rain (total 46mm), heaviest during Sat afternoon. Warm (max 29°C on Fri night, min 26°C on Sat morning). Winds decreasing (severe gales from the SE on Fri night, moderate winds from the SSE by Sun night). | Days 5-7 Weather SummaryMostly dry. Warm (max 31°C on Wed afternoon, min 27°C on Tue night). Wind will be generally light. | ||||||||||||||||||||

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.
