Table - best surf conditions forecast for Tengan over the next 16 days.
Alright folks, Rusty here. Let’s get straight into it. The next 16 days are looking pretty dismal for surf at Tengan, so don’t hold your breath for anything epic. We’ve got a long stretch of nearly nothing to kick things off, with barely a ripple until the end of the first week.
The first few days are a total write-off. From Saturday the 11th right through to the end of the week, it’s a mess. Cross-onshore winds, gale force at times, and combined wave energy so weak it’s sitting at zero (0) for days. You’d be wasting your time even looking at the ocean. This pattern holds until about the 18th of July, with only tiny, unrideable bumps and variable wind—mostly cross or cross-onshore, keeping things chopped and lumpy.
We’ve got a glimmer of hope on the 17th of July, with glassy conditions and a tiny 1 ft easterly swell, but it’s nowhere near worth paddling out. The water temperature sits at 84°F on the 11th, which is about average for the time of year, but that’s the only thing that’s normal.
The first real chance comes on Sunday the 19th of July. Tengan (reef) sees a bit of life with a 2-3 ft east swell pushing in, and the combined energy climbs to 254 (moderate). The wind is glassy in the morning, and that’s a big positive. The swell direction is E, which is on the money for Tengan’s optimum from the northeast, but it’s close enough. The swell period is 14 seconds, a nice long groundswell that will bring some proper shape, but at a reef break like this, it could be a bit too straight and fast. Still, it’s the best we’ve got. The break is inconsistent, so you’ll be waiting for waves, but when they come, they’ll be clean. The crowd is listed as “sometimes,” so expect a few locals out, but nothing crazy.
The following day, Monday the 20th, sees a similar push of 3-4 ft east swell, but the wind goes onshore from the east, so it’s not going to be clean. The combined energy is 163 (moderate), but the onshore wind will mess it up.
After that, it’s another week of poor to ordinary conditions. From the 21st to the 26th, we see some moderate swell building—up to 4 ft on the 21st—but the wind is mostly onshore or cross-onshore, which is a killer for this break. The combined energy peaks at 212 (moderate) on the 21st, but with onshore easterly winds at 12 mph, it’s going to be bumpy and blown out. There’s a brief window on the 24th with a 1-2 ft east swell and glassy wind, but the energy is weak (59), and the swell is tiny.
The final days of the outlook, the 25th and 26th of July, are basically flat again. Combined energy drops to 18 and then 9 with a tiny 0.3 ft southeast swell and a very long period of 16 seconds. That’s not doing anything for us.
So, if you’re desperate, the standout is Sunday the 19th of July. Get out there early for the glassy morning, with a 2-3 ft east swell and a moderate 254 energy. It’s not going to be a classic, but it’s the only window that’s even close to being worth a paddle. The rest of the 16 days? You’re better off doing something else.
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.
