Alright, this is Rusty. Let’s talk about Tengan.
Alright, looking at the next couple of weeks, Tengan is a tricky spot. It’s an inconsistent reef break, so we gotta pick our moments. The first half of the outlook is honestly a bit of a write-off. We get a taste of something early on, but then a lot of wind and stormy weather messes things up for a long stretch. The real standout looks like it’s gonna be much further down the line.
We start off on Tuesday, July 7th with some small but clean surf. Tuesday morning brings a 3 ft ESE swell with a long 13-second period, and the wind is a light cross-off. The wave energy is weak (318), so it’s not gonna be pumping, but it’s tidy for a beginner wave. Then Tuesday afternoon gets even better—the wind goes glassy, the swell bumps up to 3 ft from the same ESE direction, and the period stretches out to 16 seconds. The energy is moderate (519), and it’s looking absolutely glassy. For a spot that’s inconsistent, that Tuesday afternoon session is a gem.
But then things fall apart. From Wednesday morning through the end of the first week and into the second, it’s pretty grim. We get hammered by strong onshore winds, storm risks, and lumpy, choppy conditions. A big pulse of 10 ft SE swell rolls in on Thursday, July 9th, but with 30-35 mph onshore winds, it’s a complete mess—only for experts if anyone’s silly enough to try. The energy is strong (4,036-4,889), but the quality is zero. We see a few small windows, like Monday afternoon, July 13th, when a 8 ft SE swell shows up with glassy conditions and strong energy (911). That’s a big wave for a beginner spot, and for experts it could be decent, but the run of poor conditions before and after makes it a risky call.
The real highlight is saved for the tail end. On Wednesday morning, July 22nd, things finally line up. We’ve got a 5 ft NE swell with a moderate period of 9 seconds, clean offshore wind from the west, and moderate wave energy (336). The “expect good surf conditions” label is the best we see in the whole run. The swell direction matches Tengan’s optimum from the NE, and with offshore winds, it’ll be clean. For an inconsistent reef, this is when you want to be there. The only catch is the crowd—since it’s noted as “sometimes” crowded, you might have some company, but for a wave that rarely fires, it’ll be worth it.
So, the plan? Sit tight through all the wind and storms. Tuesday afternoon, July 7th, gives you a taste of what’s possible. But the real one to circle on your calendar is Wednesday morning, July 22nd. That’s your best bet for a clean, fun session at Tengan.

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.
