The Lowdown
Alright, this is Rusty. Let me tell you, it’s been a rough stretch here at Tengan. Looking out over the next couple weeks, we’ve got a whole lot of nothing to get excited about. For a reef setup like this, we need the stars to line up, and right now, they’re just not doing it.
The first couple of days are a write-off. Thursday the 3rd and Friday the 4th are a total bust with messy, poor surf conditions. About the best you could say is that the water temp is right at 84°—pretty standard for this time of year—so at least you won’t be cold while you’re sitting there getting frustrated.
You’re looking at a long, blank wait. It isn’t until Saturday the 5th of September that we see even a flicker of life, and even then, it’s a marginal call. The morning has some chest-high swell from the NNW at about 4ft, with a clean cross-offshore breeze. The combined wave energy is decent (323), but the conditions are still just ‘marginal’—questionable tide, not a full green light.
After that, it’s back to a terrible run. Sunday the 6th through to Wednesday the 17th is all just poor quality surf, with onshore winds, chop, and messy conditions. There’s some size on the 8th and 9th of September (swells around 5-6ft), but the wind is blowing hard from the north and it’s just a lumpy mess. Not worth paddling out for a beating.
Finally, on Thursday the 18th of September, something that almost counts. A clean offshore wind from the WSW, and a tiny 2ft swell from the east. The energy is weak (124) and the wave comment is “surfable waves but very ordinary conditions”. It’s not a standout, it’s just the least ugly day in a very ugly forecast.
Bottom line, this is one of those stretches where the ocean is just saying ‘no’. Don’t hold your breath; forecasts can flip, but based on what’s here, we’re not getting any good rides for a long time.

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.
