The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu.
Honestly, the outlook for Tengan is a tough one. We've got a solid two and a half weeks of poor surf conditions ahead, with nothing that really gets the heart pumping. The combined swell energy is moderate at best, hitting a peak of 857 on the 6th of September, but that comes with a messy, strong cross-shore wind that just ruins any chance of a decent wave.
We kick off on Sunday the 6th of September with an 8ft northerly swell but a strong 25 mph north wind tearing across it. It's a write-off. Through the following week, the wind shifts around but never really lines up. Monday the 7th sees a cleaner cross-off breeze, but the swell drops to 5ft and is weak, with combined energy down to 365. The rest of the week is plagued by onshore winds, keeping the surf chopped and messy.
The second week doesn't bring any hope. From the 14th of September onwards, we're looking at small, weak swells under onshore or cross-onshore breezes. There's a little spike on the 18th of September with a 7ft ESE swell and combined energy of 692, but again, onshore wind spoils it. The period on that one is only 9 seconds, so it's not going to have much grunt.
There is absolutely no standout here. Every single session is rated as poor. For a reef break that's inconsistent and only really works with a NE swell, the conditions just aren't coming together. The water is a warm 84°, which is about average for the time of year.
Given the persistent onshore winds and small, weak swells, this setup is looking far more interesting for kite surfing than paddle surfing. It’s just not worth paddling out for.
Stay tuned, things can change.
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.
