The Lowdown

Alright, crew, let’s have a look at what’s coming our way for Tengan. This spot is a reef break, and it’s a bit of a fickle one – it’s inconsistent and rarely breaks, so when it’s on, it’s a treat. But I gotta be straight with you: the next several days are a write-off. We’ve got a long stretch of nothing much happening, with poor conditions and hardly any swell to speak of. From Saturday the 22nd right through to the end of the month, it’s mostly cross-onshore winds, lumpy, choppy, and tiny surf. Not even worth paddling out for. The combined wave energy is weak, well under 100 most of that time, and the swell heights barely hit 3 ft.

Then, things start to get interesting around Tuesday the 25th. We’ve got a decent pulse of swell arriving – 10 ft from the east, with a long period of 17 seconds. That’s proper groundswell. The energy jumps to a very strong 4733, which is a lot of power. But the wind is cross-shore, and it’s rated as marginal, not clean. The tide might be a factor too. So it’s more of a “keep an eye on it” day than a go-out-and-charge day.

The real standout window opens up on Wednesday the 26th. Wednesday morning, the wind swings light offshore from the west, at just 10 km/h. The swell is still solid at 8 ft, coming from the north with a 12-second period. The combined energy is strong at 2028. This is excellent surf for experienced surfers – it’s a bit too big for beginners. The reef should be handling that north swell well, and with clean, glassy conditions, it’s going to be a session to remember. The offshore wind holds through the afternoon, keeping the waves clean. Thursday the 27th is also very good, with 7 ft swell from the NNW and light offshore winds, but the energy drops a bit to 1001. Still, that’s a solid day.

After that, the wind turns against us again. Friday the 28th sees cross-onshore winds and a drop in quality, and from there it’s back to poor conditions through the first week of September. There’s a spike in swell on the 3rd of September – 8 ft to 10 ft from the north – but with fresh cross-onshore winds at 30 km/h, the surf will be lumpy and messy. Not recommended.

So, to sum it up: the first week is a bust, then we get a nice clean window mid-week from Wednesday the 26th through Thursday the 27th. That’s the best of the lot. After that, it’s back to the waiting game.

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.
