The Lowdown
Alright folks, Rusty here. We’re lookin’ at a pretty grim stretch for Tengan. The whole 16-day window is a real struggle, and honestly, I can’t point you to a single day that’s worth paddling out for. The swell just doesn’t line up right, and when there’s a pulse, the wind spoils it.
Let’s run through it. We start off Tuesday, September 8th, with a 7ft swell from the NNW, but a stiff 19 mph wind makes a mess of it. The energy is moderate (571), but the report says poor surf conditions, and I’m not arguing. Through Wednesday and Thursday, the swell drops a little but stays junky with cross-shore and onshore winds. Friday the 11th has a small 4ft swell, but again, the wind is on it. By Saturday the 12th, we’re down to knee-high dribble.
We hit a real flat spell from the 13th all the way through to the 20th of September. That’s a solid week-plus of tiny, weak waves. The combined energy bottoms out in the double digits—a measly 17 on the 20th. Not even worth waxing the board for.
Now, there’s a glimmer way out there on Monday, September 21st. A long-period groundswell sneaks in from the ESE with a 17-second period, pushing the energy up to 757 (moderate). Swell size is 4ft. But the wind is a gentle cross-onshore, and the report says it’s marginal. The next day, Tuesday the 22nd, sees the biggest swell of the whole run—6ft from the ESE with a 16-second period, and the energy jumps to 1444 (strong). The wind is cross-shore, not ideal. This is a long-period swell, and at a reef break, that could be alright, but the conditions are only rated a 3/10. It’s promising but far from certain, and it’s over a week away. For a beginner-friendly spot, a 6ft swell with a long period might be a bit much.
For a break that’s inconsistent and best with a NE swell, the whole forecast is a bust. There’s nothing here that says paddle out. This is just one of those blank runs for the area.
Rusty, signing off.

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.
