The Lowdown
Alright, Rusty here. Let's get into it.
Alright, truth be told, this 16-day window is a bit of a struggle for Tengan. The start is basically a write-off, with the first decent opportunity not showing up until Friday morning the 4th. Let's break down the long slog to get there.
For the first few days, it's pretty grim. Wednesday and Thursday are ruled out by onshore winds and messy conditions. Hold your horses, it's a washout.
Then, on Friday the 4th, we finally see a glimmer of hope. The morning is the pick of this first week. We've got a clean, moderate offshore wind from the west, and a 5ft swell out of the north. The period is short at 8 seconds, so it'll be a bit crumbly, but the moderate energy (391) and light offshore breeze will make for some rideable, if not epic, waves. This is likely the best you're going to get for a while. The afternoon gets a bit more questionable with a cross-offshore breeze.
The weekend (5th and 6th) is a no-go. Strong winds from the north-west really kill any chance of clean surf, even though there's swell around. It'll be a frothy mess and might be more interesting for kite surfers than us paddle surfers.
The following week is a real desert. From Monday the 7th right through to Tuesday the 15th, every day is rated as poor. It's just one of those blank runs that's more normal for this area with the inconsistent nature of the reef. The swell drops right off, and when it does show up, the wind is always on it, either onshore or cross-onshore.
Now, for the far end of the forecast, there’s a glimmer of something interesting, but it's a long way out. On Wednesday the 16th of September, we have a potential standout. The morning is marginal, but the afternoon session looks legitimately special. The wind goes glassy, and a groundswell arrives from the east-northeast with a very long 14-second period. The combined energy is strong at 1374. This is the kind of long-period, powerful swell that will wrap into Tengan (Tengan) with serious push. The swell will be 5ft, but that long period makes it a lot more serious. This is definitely for experienced surfers only; beginners should watch from the shore. The ocean temperature is around 84°F which is about average for this time of year, nothing unusual there.
The next day, Thursday the 17th, still has some solid energy (1031) with a 7ft north swell, but the onshore wind comes back, making it chunky and messy again.
So, to sum it up: the only real windows are a brief, clean-ish session on Friday the 4th morning, and a very promising, glassy afternoon on Wednesday the 16th. That Wednesday is the one to circle on the calendar, but it's a long-range call so keep the hope in check.
Stay stoked, but patient.
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.
