The Lowdown

Alright folks, Rusty here. Let's have a look at what Tengan has in store for us over the next couple of weeks. Honestly, it's a bit of a rough stretch. The water temp is sitting at 83.5°F, which is pretty much average for this time of year, so nothing unusual there.

We’ve got a long dry spell to get through. From the 22nd right through to the 24th of August, it’s tiny and lumpy with fresh cross-onshore winds, making it pretty much unsurfable. You're looking at waves barely pushing 1ft with weak energy readings. Not worth paddling out for.

Things start to change on Monday the 24th afternoon. The wind switches to onshore, but the swell starts to pick up, hitting 4ft from the ESE with a moderate energy. It’s still labelled as poor, but you can see the ocean starting to wake up.

Now, the standout window looks to be Tuesday the 25th of August. The morning brings a solid 10ft swell from the ESE with a long period of 17 seconds. The combined energy jumps to a very strong level. The winds are cross-shore from the NNE at 15 mph, which is still going to put a bit of a chop on it. This is big, powerful groundswell, but with that long period, expect some longer lulls between sets. That size and power makes it strictly for experienced surfers only—beginners should sit this one out. The direction is a bit off Tengan's optimum NE, but the sheer size is hard to ignore.

Wednesday the 26th sees the biggest numbers, with a 15ft swell from the NNW on the morning. However, that comes with a near gale offshore wind at 31 mph. The energy is massive, but that wind, while offshore, is so strong it’ll be nearly impossible to paddle into and make it a battle for experts only. The afternoon drops a bit to 11ft, but with the same brutal wind. It’s more of a windsurfing or tow-in show than a paddling session.

After that big pulse, it drops off fast. From Thursday the 27th of August all the way through to Wednesday the 3rd of September, it’s a messy mix of small swell, cross-onshore winds, and crap conditions. We get another pulse on Thursday the 3rd of September with a 5ft swell from the E and a decent period of 15 seconds, and moderate energy, but the cross-shore winds from the NNE will keep it choppy and uninviting.

The last week of the forecast, from the 3rd to the 6th of September, is a washout of poor surf and onshore winds. Honestly, for this entire 16-day outlook, the only real window for a proper, heavy session is Tuesday the 25th of August. It's a big, powerful, and challenging day for those with the skill to handle it.

Stay salty.

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.
