The Lowdown

Alright folks, let’s be straight with you about Tengan. This 16-day forecast is about as bare as a winter beach. There’s simply no good surf on offer for the foreseeable future.

We’re starting off with a whole lot of nothing – through the 20th, the waves are struggling to reach 2 feet, and the winds are mostly cross-shore or onshore, chopping up what little there is. There’s even a few thunderstorms in the mix early on. You won’t need your board for that.

There is one faint glimmer of hope around the 22nd and 23rd. The swell bumps up slightly to around 4 feet from the north, and on the morning of the 23rd, we finally see some glassy conditions with light winds. That’s the only clean window in the whole period. But don’t get too excited – the period is short, around 7 seconds, so it’s going to be soft and a bit crumbly. It’s rideable, but you’ll be working for every scrap.

The energy through this whole stretch is weak. Nothing really gets moving, and most days are well under 200 in the energy department. After that one clean morning, the wind turns nasty. We’re talking strong cross-shore breezes, and by the 28th, there’s a proper gale blowing – 50-plus mph. The ocean will be churned up and the waves, while a little bigger, will be completely unsurfable. From the 29th onward, it fades right back down to tiny 2-foot dribble with onshore winds.

Water temp is pretty standard for this time of year, so no need to change your rubber.

The bottom line: if you’re a kiter, the gale days might get your heart racing, but for a surfer, this is a solid two-week blank. It’s a normal part of the rhythm out here, but it doesn’t make it any easier to swallow. Keep the board in the shed and stay patient – this won’t last forever.

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.
