Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Tengan is looking pretty grim. We’ve got a long, dry spell ahead, so let’s break it down.
We’re starting off with nothing. The first few days are a total write-off. Saturday the 11th through to Tuesday the 15th of July are all about strong, cross-onshore winds and zero surf. It’s a complete blown-out mess. The wind is howling from the SE at 50 mph to start, settling down but still onshore. You’re looking at a solid 4-5 days where you wouldn’t even bother getting the wetsuit on. There is literally no wave energy registering.
We finally see a tiny flicker of life on Wednesday the 16th. The afternoon goes glassy with a 1 ft easterly swell, but it’s tiny. The combined energy is a paltry 18 – that’s weak. The morning of Thursday the 17th is also glassy, but again, only 0.7 ft of swell. This is not surf you’d drive for. The wind is light and variable, so it’s clean, but there’s nothing to ride.
The best chance we get in this whole period lands on Saturday the 19th of July. The swell bumps up to 5 ft from the SE with an 8-second period, pushing the combined energy to 327. That’s a moderate wave pulse. However, the wind is onshore from the ESE at 12-15 mph, which is going to chop it up and make it a real bumpy, lumpy mess. This is a reef break that’s inconsistent and fairly exposed to the NE swell, but we’re getting SE wind. It’s not ideal. For a beginner, 5 ft is getting too big, and with the onshore wind, it’s going to be a challenge. The water temp is a balmy 84°F, which is pretty much average for the time of year, so no surprises there.
The following week is more of the same sad story. On Monday the 20th, the swell drops to 4 ft and the combined energy is down to 159, still with onshore wind. By Thursday the 23rd, the swell tries to pick up again to 6 ft (energy of 338) but it’s still cross-onshore from the NE. The period is short at 7 seconds, so the waves will be weak and crumbly. The whole run from the 20th to the 26th is plagued by onshore or cross-onshore winds, with the swell being either too small, too short-period, or too windy. The 22nd has a weird spike in period to 17 seconds on a tiny 1 ft swell, which is as useless as it sounds.
The very end of the run, Friday the 24th, offers a brief moment of glassy conditions with a 2 ft easterly swell, but the energy is still only 57. It’s clean, but it’s micro. Then it’s back to nothing on the 25th and 26th.
Honestly, for this entire 16-day stretch, Tengan is a no-go for a proper paddle session. The constant onshore wind and lack of a clean, well-arranged swell make it look far more interesting for a kite surfer than a regular surfer. The forecast can always change, but as it stands, you’re better off doing something else for the next two weeks. Keep an eye on it, but I wouldn’t hold your breath.
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.
