The Lowdown

Alright folks, Rusty here. Let's break down this 16-day stretch for Tengan. I won't sugarcoat it: this is a rough run. We're looking at a long stretch of small, wind-battered surf. The bright side? A couple of windows where the wind finally plays nice.

Right from the start, there's a big gap. From Tuesday, September 15th through to Saturday, September 20th, it's basically a flat spell. Tiny waves, cross-onshore wind, and choppy conditions. The water is a warm 84°, which is about normal, but don't bother paddling out unless you just want to float.

The first real chance comes on Sunday, September 20th in the afternoon. The wind swings cross-offshore from the NNW, cleaning up the surface. We'll get a bump in swell to 5ft from the east, with a solid amount of energy. It's not perfect for Tengan's preferred NE direction, but it's the cleanest wave in the first week by a long shot.

The big standout of the whole outlook is Saturday, September 26th in the afternoon. The wind goes glassy out of the ENE. The swell is a modest 3ft from the ESE, with a short period, so the energy is moderate. But with a clean, glassy face on Tengan's reef, this is the best all-around session for a beginner or anyone wanting a smooth, easy paddle. That's your day.

After that, we get a bigger pulse of swell on Monday, September 28th, with waves hitting 5ft from the SE. The energy is strong, but the wind is ugly – cross-onshore and choppy, making it a messy, blown-out mess. Not worth it. The rest of the month drifts off into small, weak surf with onshore winds.

So, the bottom line: a long flat start, one quality glassy day on the 26th, and a few promising but ruined swells. Keep the 26th circled. The rest is a pass.

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.
