The Lowdown

G’day, Rusty here, pickin’ through the Tengan forecast. Truth be told, the next week and a half looks like a real battle with the wind and slop, but there’s a flash of something wild right at the edge of the window that’s got my heart racing.

The whole opening stretch from the 26th of August right through to the 2nd of September is a write-off for clean, rideable surf—about a week of nothing but cross-shore junk and strong winds. The water’s sitting at a toasty 84°F, which is about as normal as it gets for this time of year, so at least the temperature’s not throwing any curveballs.

Then, on the 2nd of September, the whole game changes. That Wednesday afternoon sees a massive pulse of swell roar in: a solid 21ft from the NNE with a period of just 10 seconds. Now, that period isn’t the long, drawn-out groundswell we’d dream of at a point break, but the sheer size is staggering—the combined energy is reading a whopping 13738 (strong to very strong wave energy). For a reef setup exposed to the swell, this is going to be an absolute beast. The cross-off wind from the NW at 25 mph will be on your back, holding the face up, so it’ll be clean. But let’s be straight, 21ft is expert-only territory. This is not a day to be learning; this is for the chargers with a death wish and a lot of bottle. Tengan is a reef break that is inconsistent, so to see it fire like this is rare—but it’ll sure as hell be memorable. If the wind plays ball, this could be the session of the year, but it’s more than a week away, so keep an eye on it.

The rest of the window into the second week is mostly messy. There’s a bump on the 4th of September with a 7ft swell from the NW and a 10-second period, but the cross-onshore winds turn it into a lumpy, hard-to-manage mess. By the 10th of September, things quieten down again with a tiny 3ft swell from the ENE. The standout is undeniably that 2nd of September peak—but it’s a one-trick pony for the fearless.

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.
