The Lowdown

Alright, let’s talk Tengan in feet and knots. It’s a rough outlook, and I’m not sugar-coating it. This reef break is inconsistent and beginner-friendly, but the conditions are just not cooperating.

Starting Monday the 31st of August, we’ve got onshore winds and weak, short-period swell. Total waste of time. That same story keeps going through the first week—cross-onshore or onshore winds, tiny surf, and a lot of stormy weather. The wave energy is barely there, often under 100. Nothing to ride.

There’s a solid gap of several days with no decent surf. The wind doesn’t let up, and the swell direction is mostly from the east, which is onshore here. By the second week, the swell does get bigger—Tuesday the 8th of September has moderate energy (around 1165), but it’s still lumpy with a fresh cross-onshore breeze. The swell hits 8 feet on Wednesday the 9th, but again, the wind is messy and the surf quality is poor. That’s more for kite surfers than paddle surfers.

The only slight chance comes on Friday the 11th of September. Morning sees a 5 foot east swell, 11-second period, with a gentle cross-shore breeze. The energy is moderate (722), and it’s called marginal with questionable tide. It’s the best we’ve got, and that’s not saying much.

Bottom line: there’s no real surf to chase here. Water temp is about normal for the season, but that’s the only highlight. This area is in a dry spell, and it’s going to stay that way for a while.

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.
