The Lowdown

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

Well, I gotta be straight with you. The next couple of weeks are looking pretty flat and grim for the Tengan reef break. We’re in for a long, quiet stretch. From now until about the 19th of August, there's barely a ripple to get excited about. We're talking tiny waves, weak energy, and just poor conditions all round. It's a proper dry spell, so don't bother checking the charts too closely for a while.

The first real hint of something happening doesn't show up until Thursday the 20th of August. We finally get a pulse of swell, with the combined energy jumping to 383, which is moderate energy, but it's a messy one. The swell will be coming from the ESE at 6ft, but with a short period of 8 seconds and a strong cross-onshore wind from the SE at 25 km/h. It'll be choppy and lumpy, making for pretty poor surf. The wave comment says it all, really. This one's probably more interesting for the kite surfers than us paddle guys.

Then, on Sunday the 23rd of August, another pulse shows up. The swell direction is from the ESE at 3ft, but with a very long 15-second period. The combined energy is a solid 375. The problem? Howling cross-shore winds from the north at 30 km/h. That long-period groundswell will offer some lines, but the wind is going to chop it up. It's a frustrating one.

Now, Monday the 24th of August is where things get a bit more interesting. We see a cleaner setup. The swell is still ESE at 4ft with a long 15-second period, and combined energy is a strong 661. The wind goes cross-offshore from the north at a stiff 45 km/h, keeping the surface clean. This would be the standout period for experts, as the swell is big enough to have some punch. It will be clean, but those strong winds will be a challenge.

By Tuesday the 26th of August, the winds become a serious problem. We get a pure offshore from the WNW, but it's a gale at 70 km/h. The wave comment says it perfectly: "gale force offshore and extremely hard to paddle into." The waves will be clean but essentially unrideable for most people. The same goes for Wednesday, with severe gale force winds. It's a total mission to even get out.

As we head into the final days of the forecast, things settle down. Thursday the 27th and Friday the 28th see cleaner, cross-offshore winds, but the swell drops right back down to tiny, weak levels. It's a case of better conditions, but no waves to ride.

So, for the whole 16 days, don't get your hopes up. The only window for something a little more interesting is Monday the 24th of August, but that's for experts who don't mind a battle with the wind.

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.
