The Lowdown

Hey, it’s Rusty. Gotta be honest, the next 16 days at Tengan look pretty bleak. We’ve got a long stretch of poor surf ahead with only a couple of brief moments that might be worth a paddle if you’re really jonesing.

Right from the start, Monday, September 14th through Friday, September 19th, we’re stuck with tiny, weak windswell. Wave heights are barely 2ft with a short, powerless period around 9 seconds, coming from the east. The combined wave energy is weak, only just hitting triple digits at best. Winds are onshore or cross-onshore, keeping the surface a mess. Water temp is a warm 84°, which is about average for this time of year, but you won’t be feeling it because you won’t be out there.

The first little flicker of hope comes on the morning of Saturday, September 19th. We get a bump to about 3ft, and the period jumps to a very long 18 seconds. That’s real groundswell energy from the east, and the combined energy reading is a solid 695. The problem is the wind is blowing a solid 12 mph cross-shore, and this is an inconsistent reef break. That long-period swell is going to be a handful here, breaking a bit too straight. It’s a marginal call at best – keep your expectations low.

The next morning, Sunday September 20th, shows more size but worse conditions. Swell hits 6ft to 7ft with that same long 16-second period, and the energy is thumping (2031). But the wind is a fresh 22 mph cross-shore, making it lumpy and choppy. This is for experts only; too big and messy for the average surfer. Honestly, it looks more interesting for kite surfing than a paddle session.

The rest of the second week into late September is a total washout. We see a few clean spells with cross-offshore winds on the 21st and 22nd, but the swell drops off a cliff – back to 5ft or less, with periods dropping to a weak 8 seconds or worse. The energy fades fast. By the end, we’re talking tiny 0.7ft to 1ft dribble with strong onshore winds.

Look, if you’re a surfer around here, you might as well wax the board for later. Forecasts can change, but this dry spell looks pretty set in stone.

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.
