The Lowdown

G’day, I’m Rusty. Alright, let’s be straight with you – this outlook for the Tengan area is a tough one to write. We’ve got a 16-day window ahead, but honestly, there’s not a single moment where the stars align for a decent paddle. The first real surf recommendation doesn’t pop up until late in the piece, and even then it’s only marginal. So, don’t go getting your hopes up for any epic sessions.

Right now, we’re looking at a long stretch of poor conditions. From Thursday the 20th of August right through to the end of the month, the story is much the same: cross-onshore winds, a lot of stormy weather, and messy, lumpy surf. The swell energy is all over the place, from weak readings of 146 (combined energy) up to a massive 2276 on the morning of Tuesday the 25th of August, but with that strong breeze and cross-onshore wind, it’s just blown-out chaos. The wave period is short too, mostly 7-8 seconds, so no real shape or power to speak of. For a reef break like Tengan, which is a beginner spot but inconsistent, this is a write-off.

The water temperature sits at 84°F, which is pretty normal for this time of year – the anomaly is only -0.2°F, so don’t stress about the water temp.

The only glimmer in the whole 16 days comes on Wednesday the 26th of August. It’s not a standout by any stretch, but it’s the one time we get a clean window. The morning sees a cross-offshore wind from the NW at 19 mph, with a 4 ft swell from the east at a long 14-second period. The wave energy is moderate at 585. Then in the afternoon, the wind shifts to a true offshore from the WNW at 19 mph, and the swell holds at 4 ft from the ENE, still with a nice 14-second period. The energy drops a bit to 433, but it’s clean and offshore. The guidance says this spot is only rated 2/5, it’s inconsistent, and it’s a beginner reef, so don’t expect a world-class session. But, if you’re keen for a paddle, this is your only shot. The swell direction is close to the optimum NE, so the break might offer a few fun ones.

After that, we’re back to poor conditions. A few days around the 27th and 28th of August have offshore winds and clean conditions, but the swell is tiny – only 3 ft to 4 ft from the north – and the energy is weak (151-172). It’s not enough to get excited about.

From the 29th of August into early September, the swell drops right off. We’re looking at waves under 3 ft, and from the 2nd of September onward, the swell pretty much vanishes. The wind turns cross or onshore, and the energy readings are in the 20s and 30s. It’s flat, plain and simple.

So, truth is, the only day worth even mentioning is Wednesday the 26th of August. If you can get out then, you might find a clean, long-period groundswell with offshore winds. But it’s a long time to wait for a marginal session. Fingers crossed the forecasts change, because this is a pretty blank run for the area.

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.
