The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this outlook for the upcoming stretch is a tough one. We're looking at a long, dry spell with barely a window of decent surf. The first real recommendation doesn't even pop up until Thursday afternoon, the 3rd of September, so we've got a couple of days of flat or poor conditions to sit through first.
Wednesday the 2nd is a write-off. Onshore easterly winds are blowing straight into Tengan, a reef setup, with a messy 5ft east swell. The energy is weak (382), and it's just poor out there. Thursday morning stays marginal with a cross-offshore wind, but the real flicker of hope comes Thursday afternoon. The wind swings offshore from the west at 12 mph, cleaning up a 4ft easterly swell. The energy is moderate (340), and the wave comment says "expect good surf conditions." It's a beginner-friendly spot, but it's inconsistent, so don't expect a constant line-up. The water temp is a balmy 84°, which is bang on average for this time of year, so you won't need a wetsuit.
Friday the 4th rolls in with a risk of thunderstorms and a small, short-period 4ft northerly swell. The wind is cross-offshore in the morning, but the energy is weak (211) and the conditions are just "ordinary." By the afternoon, the swell drops to 3ft and the energy fades to 108 – it's a paddling session at best.
From Saturday the 5th right through to Tuesday the 15th of September, it's a grim run. The wind is almost always onshore, cross-onshore, or cross-shore with chop, and the swell quality is consistently rated as "poor surf conditions." The energy levels bounce around, but the wind ruins it every time. There's a brief spike on Thursday the 10th with an 8ft NNW swell, but it's accompanied by a fresh 22 mph north wind that creates a lumpy cross-chop. That's kite-surfing territory, not paddle surfing. The period is short (9-10 seconds), so it's a messy, bumpy windswell.
The last week of the outlook is more of the same. On Wednesday the 16th, we get a 7ft NNW swell with a short 8-second period, but the wind is again a fresh cross-shore, making it lumpy. The 17th of September sees a solid 8ft northerly swell with a longer 11-second period, and the energy is very strong (1546). But again, the wind is a strong 22-25 mph cross-shore, creating a messy cross-chop. That's a big, unruly wave for experts only, and the wind is going to make it a battle. For a reef break like Tengan, that long-period swell can be good, but not with that wind.
Honestly, the only standout in this whole 16-day window is that Thursday afternoon on the 3rd of September. It's a short window, but if you can get out there, you'll have clean, offshore waves on a beginner-friendly reef. Everything else is a write-off. The crowds here are listed as "sometimes," so you might have some company, but it won't be a zoo. Don't hold your breath for the rest of the run.
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.
