The Lowdown

Hey, Rusty here. Alright, so this forecast for Tengan is a long 16-day stretch, and it's mostly a waiting game. The reef's got some pulses, but the wind keeps shutting it down.

Starting Sunday the 6th of September, there's a 6ft NNE swell, but it's cross-onshore at 19 mph with thunderstorms around. Water temp is 84°, which is normal for this time. Combined energy reads moderate (470), but the onshore makes it a write-off.

Monday the 7th is cleaner with a cross-off wind, a 7ft NNW swell, and moderate energy (521), but still marked poor. Tuesday the 8th drops to 4ft from the N, cross-off, but nothing special.

From Wednesday the 9th all the way through the 16th, it's grim. Onshore winds from the E at 22+ mph, lumpy chop, and swell mostly under 4ft. Energy drops to 54 (weak) by late September.

The first decent break is Thursday the 17th. Light cross-off wind from the SW, a 4ft ESE swell with a 10-second period, and moderate energy at 294. It's cleanish, but the wave comment says "marginal." This is your best shot.

Then Friday the 18th brings glassy conditions—wind from the WNW at just 3 mph, a 5ft N swell with a short 6-second period. Moderate energy at 225. It'll look smooth, but it's a short-period wave.

So, Thursday the 17th and maybe Friday the 18th are the only real options. Everything else is blown out or tiny. For Tengan, this is just one of those quiet runs.

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.
