The Lowdown

G’day, Rusty here. Look, I’ll level with you – the next week or so is a real struggle for Tengan (reef). We’ve got a pretty grim run of poor surf conditions, with strong onshore winds and lumpy, messy waves. The water temp is sitting at 84°, which is bang on average for this time of year, so no surprises there.

The first good news doesn’t show up until Wednesday the 26th of August. That morning, we see a big shift – a clean 7ft swell from the ESE, with a very long period of 16 seconds, and a fresh cross-offshore wind from the NNW to clean it up. The combined energy is strong at 2451. That’s a serious groundswell, but on a reef, this long-period stuff can line up beautifully. It’s a standout for the forecast, but it’s a ways out, so keep an eye on it.

Thursday the 27th of August morning is also looking solid. We’ve got a 6ft E swell with a 14-second period, and a fresh offshore wind from the W. The combined energy is still strong at 1756, and the clean conditions should make it a ripper. The afternoon holds a similar 6ft ENE swell with a 15-second period and offshore WNW wind – another quality session.

Then, Friday the 28th of August is a real mixed bag. The morning brings a 8ft NW swell, but with a short period of 7 seconds. It’s clean with a moderate offshore wind, but that short period means it’s going to be a bit fat and less punchy. The combined energy is moderate at 704. Still, it’s surfable and clean.

The absolute gem of the whole forecast looks like Saturday the 29th of August afternoon. The wind drops to glassy, with a light SSE breeze of just 5 km/h. The swell is a solid 7ft from the NNW with a 11-second period, giving strong combined energy of 1066. It’s glassy, clean, and that’s about as good as it gets. The morning is also good with a light cross-shore wind and a 8ft NNW swell, but the afternoon is the real podium.

After that, it drops off again. Sunday the 30th of August is back to poor, cross-onshore and choppy, and the start of September looks like a lot of clean but very large swell. On the 1st of September, we’re looking at 10ft ESE swells but with a moderate cross-shore wind – that’s big, over 8ft, so experts only. Then the 2nd and 3rd of September bring 13ft to 15ft ENE swells with clean cross-offshore winds, but that’s massive, powerful energy in the thousands. That’s big-wave territory, not for the faint-hearted.

So, your best windows are clear: Wednesday 26th and Thursday 27th of August for the clean, long-period groundswell, and the absolute standout is Saturday 29th of August afternoon for the glassy, quality surf. Don’t bother paddling out much before then unless you love a beating from the wind.

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.
