The Lowdown

Rusty

Alright folks, Rusty here. Let's be real, looking at the next 16 days for Tengan, it's a tough watch. The forecast is a long, drawn-out run of mostly poor conditions with only a few brief windows that might be worth a look. We're starting with a gap of nothing but flat, weak surf from Saturday the 1st all the way through to late Sunday the 2nd. The first chance to get wet comes Sunday afternoon, but it's a real struggle.

Sunday the 2nd finally sees a little bit of life. The afternoon session brings a tiny 2 ft swell from the east with a period of 17 seconds. That's a long-period groundswell, which for a reef break like Tengan is a good sign for shape, but the size is barely there. The wind is a light cross-offshore breeze, which will keep the surface clean. It's surfable, but you'll be fighting for tiny, gutless waves. The combined energy is a paltry 165 (weak), so don't expect much push.

Monday the 3rd sees a slight bump in size, up to 3 ft – 3 ft from the east-southeast, with a period of 15-16 seconds. The combined energy moves into the moderate range at 294-422, but the wind turns cross-shore, putting a little chop on the face. It's still marginal, and the tide will be a factor. It's a speck of hope, but nothing to get excited about.

Tuesday the 4th is about the best we get. The morning session has a clean 4 ft east swell, an 18-second period, and combined energy of 903 (moderate). The wind is a light cross-shore, and the water is a touch warmer than normal at 86°F, which is a nice bonus. The afternoon picks up to 4 ft, but the wind swings cross-onshore with a risk of thunderstorms, so grab the morning window. Even then, the overall quality is still rated as marginal.

From Wednesday the 5th onwards, things get ugly. The swell pumps up, reaching 7 ft on Wednesday and 13 ft by Thursday, but the wind does the same, turning into a howling, choppy mess. By Friday the 7th, we're looking at a massive 33 ft swell from the north-northeast, but with a storm-force 95 km/h cross-shore wind. The combined energy at that point is a staggering 50,680 (very strong). That's not surfable, it's a survival situation. For an inconsistent reef break like Tengan, that's a hard pass for anyone with a paddleboard.

After that, the swell drops off a cliff, and we're back to tiny, messy windswell and brutal hurricane-force winds for the rest of the second week. There's honestly nothing worth chasing in that period.

The Bottom Line: The best chance is a short window on Tuesday morning, the 4th of August. It's not a classic, but it's the only window where the swell, wind, and energy line up enough to make it a real option. The rest of the 16 days is a right-off for anything decent.

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.
