The Lowdown

G’day, Rusty here, mate. Look, I’ve had a good look at the charts for Tengan, and I gotta be straight with you—this is a rough stretch. We’re looking at a solid 16-day window, and honestly, the surf is either too wild, too small, or just plain messy for most of it. There’s a big gap at the start with nothing worth paddling out for, and even when the swell shows up, the wind just ruins the party. Let’s break it down.

The first bit of halfway decent energy doesn’t show up until Friday the 4th of September. But even then, it’s not great. We’ve got a 8ft swell from the NNW with a long 12-second period on Friday morning, which gives it some grunt and shape potential—combined energy is a solid 1592 (moderate wave energy). But the wind is cross-shore from the south at 16 mph, creating a messy cross-chop. It’s a marginal call at best, and for a beginner spot like Tengan, that’s too much size and wind. After that, it’s back to poor conditions with onshore winds and lumpy seas through the weekend and into the next week.

Now, if you’re looking for the one standout, it’s gotta be Thursday the 3rd of September. We’re talking a big 16ft swell from the NW, with an 11-second period—that’s proper groundswell energy, and the combined energy reads 5391 (strong wave energy). The wind is a cross-offshore from the SSW at 31 mph, which means the face should be clean, but that wind speed is near gale-force. This is for experts only—16ft waves are huge, and you’d need a death wish or a jet ski. The water temp is 84° and the anomaly is -0.2°, so basically average for the time of year. Tengan is a reef break, so that long-period swell will wrap in nicely, but the direction is off-optimum—it’s coming from the NW, while the optimum for Tengan is NE. The crowds are sometimes an issue here, but on a day like this, you’ll have the place to yourself. Still, it’s a big, gnarly day.

For the rest of the period, it’s a write-off. From August 26th right through to September 3rd, there’s no surf worth mentioning—wind is howling, swells are tiny or blown out. Then after the 4th, it’s consistent but poor, with onshore winds and messy conditions right through to the 10th. No other standout breaks are on offer.

In short, Thursday the 3rd of September is the only proper session for the big dogs, but even then, it’s a battle. For everyone else, leave the boards at home and maybe take up kite surfing—that south-east wind on the 2nd and 10th would be perfect for that.

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.
