The Lowdown

Alright folks, Rusty here. Let’s look at what’s on the cards for the Tengan stretch.

Right now, the whole 16-day window is a tough one for the area. The reef at Tengan is a beginner spot, but it’s inconsistent and only exposed to a NE swell. For the vast majority of the period, we’re looking at a lot of flat spells or choppy, wind-affected conditions. The one little window of interest comes around August 4th, but even that’s a bit of a stretch.

From the start, through the end of July and into the first days of August, it’s mostly tiny wave energy. The combined energy is weak, sitting in the single or low double digits (9 to 17), and the swell heights are barely registering at 0.7 ft to 1 ft. The wind is light, sometimes glassy, but there’s just no swell to work with.

Then we get a slow build. On August 2nd, the swell picks up a notch, but the energy is still low (97) with a 1 ft wave. The wind is clean and cross-off, so it’s not a total write-off, but it’s still pretty gutless. August 3rd sees a jump in combined energy (329 to 443) with a 3 ft to 3 ft swell from the ESE, but the wind turns cross-shore and moderate, putting a chop on it.

August 4th is the standout, but it comes with a big caveat. The morning of August 4th, the swell builds to 5 ft from the East with a long 18-second period, and the combined energy hits 1289. It’s a moderate energy groundswell. The problem is the wind – a moderate cross-shore breeze. The surfing is marginal, and the tide might be a factor. The afternoon sees the swell tick up to 5 ft and energy jumps to 1620, but the wind strengthens to 16 mph, making it choppy. This is the best the outlook has to offer, but it’s far from perfect. For a beginner zone, the 5 ft to 5 ft swell is pushing the limit. The long period (18s) means the sets will have some punch and there will be long lulls, which can make paddling out easier, but at a reef break, it might be a bit tricky.

After that, it gets messy. August 5th is too big for beginners at 8 ft to 10 ft, with a strong cross-shore wind and a lumpy chop. From August 6th onwards, it’s a write-off. We’re talking about a severe gale, hurricane-force winds, and dangerous storm conditions. August 7th has a 20 ft swell with violent storm force winds. Do not even think about it. The forecast then settles a bit after the 8th, but the swell drops back to a tiny 2 ft to 3 ft with strong onshore winds and poor quality.

So, to be brutally honest, there’s a tiny, marginal window on August 4th. The rest of the 16 days is a flat, windy, or stormy mess. This is one of those stretches where the area just doesn’t have the right wind and swell alignment. You’re better off waiting for the next cycle.

Keep your head up, the forecasts can always change.
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.
