The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, it's a tough stretch. The overall pattern is a long, drawn-out wait for very little reward. We're looking at a major gap with no real surf on offer. The first truly usable window doesn't appear until Thursday afternoon, the 10th of September, and even then it's just a glimpse. The rest of the period is mostly a write-off due to poor conditions, strong winds, or tiny swell.
The first chance to get wet is at Tengan, a reef break. It's an inconsistent spot, so you have to pick your moments. The standout session is Thursday afternoon, the 10th. We'll see a clean 5ft swell from the north, with a period of 10 seconds. The wind will be glassy, which is a huge plus, making for a clean, smooth surface. The combined wave energy is moderate at 500. It's a beginner-friendly break, but with that 5ft swell, it might be a bit much for absolute novices. Get on it while you can because after that, it's a long dry spell.
From Friday the 11th right through to the end of the run, every forecast is for poor surf conditions. The wind is a constant problem – mostly onshore or cross-onshore, with some strong breezes and even a near gale by the 23rd and 24th. The swell gets bigger towards the end, with a 5ft to 6ft swell from the south-east around the 22nd and 23rd, and the wave energy is high (over 1300), but it's accompanied by 25 to 31 mph winds, making it an absolute mess. That's more interesting for the kite surfers than anyone with a paddle. The water temperature is about average for the time of year.
This is a classic case of a blank run for the area. It doesn't stay poor forever, but this window is a tough one to crack. Keep your eyes on the sky, but don't get your hopes up.
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.
