The Lowdown

Alright folks, Rusty here. Let's get into it.

Right off the bat, I gotta say, this is a tough stretch for Tengan. We're looking at a whole lot of nothing for the next week and a half at least. The first real blip of surfable energy doesn't show up until the very end of the run, and even then it's barely a whisper. So, brace yourselves for a long flat spell.

Let's talk about the one and only break we've got to work with: Tengan. It's a reef setup, but it's inconsistent and only really works with a NE swell. The water temp is sitting at a warm 86°, which is a touch warmer than usual for this time of year, so you'll be comfortable in boardies or a spring suit.

The first few days are a write-off. Small waves, cross-shore winds, and a lot of energy that's just not directed our way. From Sunday the 2nd through to the end of the first week, we're looking at poor surf with marginal conditions. The swell is tiny, and the wind is mostly cross or cross-onshore, making it a messy picture. The combined energy values are all over the place, but even when they spike, like on Wednesday the 5th with a 7 ft swell from the east and a combined energy of 3096, the wind is choppy and onshore, ruining any chance of a decent wave. The standouts from the 7th to the 8th are a whole different problem. We get a massive pulse of swell, like 30 ft from the north, combined energy hitting 31100. Way too big for this spot. The wind is actually clean, but you'd be a fool to paddle out. That's a big-wave tow-in zone, not a paddle session. The period is short, around 11-13 seconds, so it's a messy windswell anyway.

After that, the surf drops off a cliff. From the 9th of August until the 16th, we get nothing but tiny, inconsistent waves. The wind is all over the shop, from hurricane-force to light breezes, but none of it matters because the swell is essentially non-existent. The combined energy drops to double digits and single digits. There's a brief flicker of life on the 13th and 14th with a tiny 1 ft swell from the ENE, but the period is 11 seconds and the energy is only 41, so it's just lakey dribble.

The best of the best, if you can even call it that, is the very last day in the forecast. Sunday the 16th of August. Tengan is looking at a tiny 1 ft swell from the east-northeast with a period of 10 seconds. The combined energy is a pathetic 35. But, and this is a big but, the wind is glassy. Absolute flat calm. That means the surface will be like a mirror. If you're a complete beginner, or you just want to bob around on a foamie, this is your window. It's not a wave you'll get barrelled on, but it's clean. The swell direction is east-northeast, which is close to the optimum NE, so it might just wrap in with a little bit of shape.

Honestly, the first 14 days are a total write-off. The surf is either too small, too messy, or too big. The only real standout, and I'm being generous, is that glassy Sunday afternoon on the 16th. For a beginner, that's a solid option. For anyone else, it's a time to wax your longboard and enjoy the sun.

Rusty out.

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.
