The Lowdown
Alright folks, Rusty here. Gotta be straight with ya – the outlook for the next 16 days is a real tough one for surfers. The whole period is basically a blank run, and there's no good surf on offer right now or for the foreseeable future. That’s just how it goes sometimes in this area – when the conditions don't line up, they really don't line up.
Looking at the whole stretch, it’s a long, quiet grind. The first few days are a write-off. Monday, August 31st, we’ve got a clean 3 ft swell from the ESE, but the wind is howling onshore at 16 mph, so it's just a mess. That pattern of onshore winds and messy conditions pretty much sticks with us for the first week.
There’s a tiny flicker of hope on Thursday, September 3rd. The afternoon shows a light 3 ft east swell with a cross-offshore breeze, which is about as clean as it gets in this window. The combined energy is weak (123), so it’s barely a ripple. The swell direction is east, but the optimum here is from the NE, so it’s not a great match. It’s the only day that gets a "surfable" nod, but it’s pretty ordinary.
After that, it’s back to the same story. We get a bit of a lift in size around September 7th and 8th, with waves hitting 5 ft to 6 ft, but the period is a short 6 seconds, and the winds are all onshore or cross-onshore, trashing any quality. The energy gets up to moderate levels (243), but it's all windswell junk. Not worth paddling out for.
The second week looks even more hopeless. The swell drops off, the winds stay messy, and there’s nothing to recommend. Even the long-period groundswell that shows up on September 9th (12 seconds) gets blown out by onshore wind. All in all, this is a solid 16-day stretch of no-good surf. Hold tight, check the forecasts again in a few days – things can change.
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.
