The Lowdown

Alright folks, Rusty here. Let's see what Tengan has in store for us over the next couple of weeks.

Right off the bat, we're looking at a pretty grim start. The water is sitting at 84°F, which is dead average for this time of year, so that's no consolation. From Thursday the 27th right through to the end of the month, it's a write-off. We've got a mix of cross-onshore and onshore wind, mainly from the south and east, with surf barely reaching 1ft to 5ft and a weak combined energy (31 to 502). The wave comment is consistently "poor surf conditions." You’d be better off doing something else.

Even when we hit the first of September, the action is still pretty marginal. The standout, if you can call it that, is Tuesday afternoon, the 1st of September. The swell jumps up to 15ft from the SE, with a solid 11-second period and a massive combined energy of 5308. That's some serious grunt. The wind goes offshore from the west at 22 mph, which should scrub the face up nicely. But let's be real, that's a big, powerful swell for a reef break. It's going to be a heavy, expert-only affair. The Tengan (Big Island) reef will be cranking, but only for the chargers.

We get a little window on Wednesday morning, the 2nd of September, with 6ft ESE swell, offshore wind from the WNW, and a clean look. The energy is a moderate 302, so it's much more manageable. That's your best bet for something a bit more user-friendly, but the score only calls it a "2," so it's not a classic.

The rest of the first week of September is a mixed bag of messy cross-shore winds and poor surf, with a few spikes of big, unmanageable swell. The 3rd of September afternoon sees another 15ft spike, this time from the ESE, but it's a short 8-second period, making it more of a washing machine than a wave.

For the second week, things don't really improve. The pattern sticks to small, weak swells with cross-shore winds, and the forecasts are less certain. You might get a small, clean window on the morning of the 10th of September with a light breeze, but it's only 3ft from the north. It's surfable, but nothing to get excited about.

Honestly, this is a tough outlook. The only real standout is that Tuesday afternoon on the 1st of September for the hardcore crew. For everyone else, it's a long wait with not much to show for it.

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.
