The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s brewing for your local line-up. I gotta be straight with you – the next two weeks look pretty grim for a proper paddle. There’s nothing that gets the heart pumping until we get deep into September, so you might want to find something else to do for a while.

We’re looking at Tengan, a reef break that’s pretty exposed to swell, but it’s inconsistent and best for beginners when it’s small. The water temp is sitting at a warm 84°F, which is bang on average for this time of year, so no surprises there.

The first real glimpse of anything rideable shows up on the morning of Thursday September 3rd. We’ve got a 5 ft swell from the north with a period of 9 seconds, pushing 343 units of energy. The wind is blowing fresh offshore from the WNW, which will clean things right up. It’s still a bit marginal, and only a 1 out of 10 on the quality scale, but it’s the best we’ve seen in a long dry spell.

Honestly though, the standout moment is the morning of Tuesday September 8th. We get a cleaner 4 ft swell from the ESE with a period of 9 seconds, delivering 272 units of energy. The wind drops right out to a gentle breeze from the NW, giving us a cross-offshore flow that will leave the surface glassy. The forecast says “expect good surf conditions,” and for this stretch, that’s as good as it gets. The swell direction (ESE) lines up nicely with the optimum from the northeast for Tengan, so the reef should handle it well. Just remember it’s an inconsistent break, so you’ll be waiting for the sets.

The morning of Wednesday September 9th is also worth a mention. Another 5 ft from the SE with a 9-second period, bumping the energy up to 437. The wind stays light and cross-off from the north, keeping it tidy. The waves will have a bit more punch.

The rest of the window is a write-off. We’ve got several days of strong winds, lumpy cross-chop, and onshore junk from August 25th right through to September 2nd. Don’t even bother. After the 9th, it trails off again into poor, weak conditions.

So, to sum it up: hang tight. September 3rd might give you a few, but September 8th is your best bet for a clean session at Tengan. Long-range, so keep an eye on it, but this one has promise.

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.
