The Lowdown

Alright, mates, Rusty here. Let's break down what's on offer for Tengan over the next couple of weeks. It's a real mixed bag, so listen up.

First thing, the water temp's around 84° – pretty standard for this time of year, nothing to write home about.

The forecast starts off real ugly. Wednesday the 26th and Thursday the 27th are completely blown out with strong, messy winds and tiny, weak waves. Friday and Saturday are no better – onshore junk. You'd be a fool to paddle out for the first few days. Don't even bother.

Things start to change as we move into the first week of September. Monday the 1st and Tuesday the 2nd see some serious energy pop up, with combined swell energy hitting the thousands (715 to 5959). We're talking solid 8ft to 18ft swell, mostly from the east and north-northwest, with clean cross-offshore winds. Tengan is a reef break, which usually likes a longer period, and this stuff has got some decent push (12-14 seconds). The quality is still a bit iffy, but for the big-wave hunters, it's getting interesting.

Here's the big one. Thursday the 3rd of September. Glassy morning, dead calm wind, and a solid 16ft northwest swell with a 12-second period. The combined energy is massive at 7695. This is powerful, long-period groundswell hitting a reef. For experts only – at 16ft, this is going to be a test of nerve and skill. It'll be clean and powerful, and you might not have hordes of people, but it's a reef, so the crowd will be there for the good ones. This is the session to circle.

After that, it drops off a cliff. Friday the 4th and the weekend of the 5th and 6th look poor again with onshore winds and weak, choppy surf.

Another window opens on Monday the 7th of September. We get glassy conditions again in the morning with a solid 10ft northwest swell. The wind stays clean and cross-offshore into the afternoon. The energy is strong (1344), but the period is a bit shorter at 8 seconds. It'll still be excellent for experienced surfers, but the shorter period might make it a bit fat on the reef.

The second week into September looks pretty average – a lot of onshore and cross-shore winds with moderate to strong swell, but the quality is gone. It's going to be choppy and messy from the 8th onwards, so it's not looking good.

In short: a long drought to start, then a massive, expert-only day on September 3rd, a decent but shorter-period option on the 7th, and then back to mediocrity.

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.
