Alright folks, Rusty here. I’ve had a good look at what’s coming our way, and I’ll be straight with you – this stretch is a bit of a mixed bag. The first few days are a write-off, with barely a bump and some tricky winds. But there’s a window of proper groundswell mid-week, if you’re patient. The water’s sitting at 81°, which is a bit colder than normal for the time of year, so a steamer might not go astray.
Tengan is the only break in the game here, a reef setup for the beginners, but it’s inconsistent and only breaks now and then.
We’re staring at a flat spell right through Friday, July 3rd to Sunday, July 5th. Tiny 1ft to 1ft swells from the ESE with periods barely hitting 9 seconds and cross-off winds. No energy to speak of (energy as low as 14-25). You’d be wasting your time.
Monday, July 6th stays small and ordinary, but Monday afternoon sees a flicker of life: a 1ft swell from the ESE, but the period jumps to 15 seconds. That’s long-period energy, but the size is pathetic, so it’s still a no-go. The energy reading is 43 – weak.
Now, Tuesday, July 7th is where things get interesting. Tuesday morning starts to build, with a 3ft swell from the ESE, period up to 14 seconds, and the energy ramps to 447. Winds are light cross-shore, creating a light cross-shore chop. Then Tuesday afternoon – this is the standout of the whole outlook. We’ve got a 4ft swell from the ESE, a massive 18-second period, and the energy is pumping at 954. The wind goes cross-off and light, making for clean conditions. For a reef break like Tengan, that long-period groundswell will wrap in nicely and offer good shape. This is the best session on offer.
Wednesday, July 8th is a different story. The swell jumps to 8ft from the SE with a 18-second period, and the energy is huge at 3442 – very strong. But the wind switches to a cross-on from the NE at 9 mph, making it choppy. By the afternoon, the wind picks up to 12 mph, the swell hits 8ft, and conditions turn poor. That’s expert-only territory with messy surf.
Thursday, July 9th is a write-off. The swell is 12ft from the SE, with strong onshore winds from the NE at 18-22 mph and energy over 6000. It’s lumpy and dangerous. Plus, there’s a risk of thunderstorms. Leave the board at home.
Friday, July 10th through Saturday, July 11th are a complete mess. Strong onshore winds from the ESE and SE, gusting up to 31 mph, with zero swell data. This is more like a kite-surfing setup.
Sunday, July 12th to Monday, July 14th is a drop back to tiny, weak swells. A few 0.3ft to 0.7ft E swells, with moderate cross-shore winds. Not worth paddling out.
Thursday, July 16th brings a small, clean window. Thursday morning sees a 2ft swell from the ESE with a 13-second period and glassy conditions – dead calm. Energy is moderate at 157. It’s surfable but very ordinary. Thursday afternoon gets a little bigger at 3ft from the ESE, 14-second period, but cross-on winds ruin it.
Friday, July 17th pumps back up, but with terrible wind. A 7ft swell from the E, 17-second period, and a strong 25 mph cross-on wind from the NE. The energy is 2798, but it’s a messy, lumpy affair. Only for the experienced and foolish.
Saturday, July 18th is small again – 2ft from the NNE with a 10-second period and light onshore wind. Poor conditions.
So, to wrap it up: the one true standout is Tuesday afternoon, July 7th at Tengan. That’s the cleanest, most powerful session on offer, with a solid 4ft groundswell and light cross-off winds. Get on it if you can. After that, Thursday morning, July 16th offers a brief, small glassy window if you’re desperate for a skate.
Rusty.

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