Alright, let’s take a look at what we’ve got for Tengan over the next couple of weeks.

Honestly mate, it’s a tough stretch. The first week is pretty much a write-off. We’ve got solid swell pulsing in from Wednesday the 9th onwards, with waves pushing well over 8 feet and into the 16-20 foot range by the 10th, but the wind is absolutely murdering it – strong onshore and near gale-force. That’s not surfable, that’s survival. The combined energy readings are massive – but with those winds, forget it. This setup at a reef break with that much power and wind? Probably more of a kite-surfing scene than a paddle session.

Then from the 11th to about the 15th, it goes flat or tiny. We’re looking at waves that barely push 1 foot to 4 feet, with short, weak periods and still messy winds. The energy drops right off. There’s nothing worth paddling out for there.

There’s a tiny glimmer of hope around Thursday the 16th morning – a little pulse of about 4 feet from the ESE, period around 10 seconds, light breeze. It’s marginal at best, but it’s the cleanest window in a bad run. The wind is light cross-onshore, so it might be okay if the tide lines up, but don’t expect much.

The second week is a slow burn. By Tuesday the 21st, we start seeing a better pulse – 5 to 6 feet from the ENE, with a long 16-17 second period. That’s proper groundswell energy. The wind is onshore but light to moderate, so it’s not blown out. A reef break like Tengan can handle that long-period energy well, but it might make it a bit straight. Still, that’s the best looking window in the whole 16 days – I’d be watching Tuesday the 21st afternoon closely.

By the 22nd and 23rd, the swell gets bigger again – up to 11-12 feet – but the winds turn fresh and cross-onshore, and with the direction swinging more NW, it’s likely lumpy and ugly.

Water temp at Tengan is currently 83°, which is about average for this time of year – nothing unusual there.

So overall, the standout is Tuesday the 21st into maybe Wednesday morning, with chest-to-head high swell and long-period energy. If the wind holds light, that’s your best bet. The rest of the window is either too big and windy, or too small and weak. Hang in there.

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.
