The Lowdown

G’day, Rusty here. Let’s be straight – the next two weeks at Tengan are a bit of a tough watch. This is a reef break that’s inconsistent at the best of times, and right now there’s a long, long gap of nothing worth paddling out for. The first sign of anything rideable doesn’t show up until Saturday the 20th of September, so there’s a solid week of flat or junky conditions before that.

Right now, through the start of the period, it’s all weak, onshore wind, and tiny – mostly 1 foot to 2 feet with short period slop. The combined wave energy is pitiful – values in the low double digits and triple digits under 150 (like 104 down to just 14). Wind’s blowing from the ESE or ENE, straight on or cross-onshore, and the water temp is sitting at 83°, which is about average for this time of year. But it’s all poor surf, no two ways about it. Even the reef can’t save this.

Moving through the week, there’s no real improvement. Tuesday the 16th through Friday the 19th stays small and messy – 2 feet to 2 feet, short period, combined energy still mostly under 100 or barely over 100. Wind stays onshore or cross-onshore, often moderate, with some lumpy chop. Not a single standout in there. Just flat waiting.

Then we hit Saturday the 20th of September – and here’s where the energy finally shows up. Swell jumps to 7 feet from the east, with a 15-second period. That’s proper groundswell. Combined energy rockets to 1989 – that’s strong, deep ocean energy. BUT – wind is ripping from the north at 31 mph, cross-shore. That’s near gale. For Tengan, a reef break, that much wind will make it a wild, blown-out mess. This one’s for experts only if they’ve got the nerve, and honestly, the setup looks more interesting for kite surfing than paddle surfing in those conditions.

Sunday the 21st of September stays heavy: 6 feet from the north, 10-second period, combined energy 686, but again wind is screaming – 43 mph from the SSW, cross-off. That cross-off wind cleans it up, but 43 mph is gale territory. Ripping current, gnarly paddle out. Not a fun one for most.

Monday the 22nd of September drops a bit: 6 feet from the north, period 10 seconds, combined energy 573, but still gale-force SSW wind at 40 mph, cross-off. Clean but terrifying.

After that, the swell winds down. Tuesday the 23rd of September shows 2 feet from the north, 8-second period, but now we get west wind at 19 mph, which is offshore for Tengan – that’s glassy, clean. Combined energy is only 107 though, so it’s tiny, weak. Not a standout, but a little window of clean small waves for the patient ones.

The final days of the outlook peter out into nothing – Saturday the 27th of September morning has 0.6 feet, glassy, with combined energy just 16. Flat calm.

So, if you want my honest call: there’s no true standout in this 16-day window. The only real pulse of size is Saturday the 20th of September through Monday the 22nd of September, but wind is dangerous, and the break is inconsistent anyway. Beginners, steer clear. Experienced surfers might find a window on the 23rd morning with offshore wind, but it’s ankle to knee high. A long blank run like this is not unusual for Tengan – when it’s off, it’s really off. Forecasts can change, but right now, it’s one to sit out.

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.
