The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s on offer for Tengan over the next couple of weeks. I gotta be straight with you – it’s a tough stretch for this spot. We’ve got a lot of poor surf conditions and not much to get excited about for the vast majority of the forecast.

We’re looking at a long, long gap with no decent surf options. The first 13 days are essentially a write-off for Tengan. For the first week, from Friday the 11th all the way through to the middle of the following week, we’re stuck with minimal swell. Swell heights are mostly between 1 ft and 3 ft, with short periods under 10 seconds, and the wind is a constant cross-onshore or onshore breeze. It’s choppy, weak, and just not worth paddling out. The combined wave energy is weak, hovering between 72 and 134 for that whole first week – just no power behind it.

Even when we start to see some bigger swell numbers around the 19th and 20th of September, it comes with a catch. By Saturday the 19th, the swell kicks up to 4 ft to 6 ft from the ESE with a very long 16-second period, and the energy jumps up to strong levels (924 to 1703). But that NNE wind is howling at 15 mph, cross-onshore, making it messy. By Sunday the 20th, it’s even bigger – 10 ft from the ESE – but that wind will be even stronger at 22 to 25 mph, turning the place into a lumpy, messy mess. This isn't surfable for a paddle, it’s more of a kite-surfing setup.

Then on Monday the 21st, it gets out of hand. The swell is predicted to be 20 ft from the ESE, with gale-force onshore winds at 43 mph. The energy reading is a massive 22970, so there’s plenty of ocean moving, but the wind and tide are only favorable if you’re talking about surviving a hold-down. It’s strictly for experts if anyone’s crazy enough. Tuesday the 22nd gets even more extreme offshore, with a 26 ft SE swell and storm-force offshore wind at 56 mph. The energy is a staggering 26146, but that offshore wind will be so strong you won't be able to paddle into it. It’s impossible.

After that storm passes, we finally get a clean-up. Wednesday the 23rd is still small with clean, strong offshore wind but hardly any swell. But then, Thursday the 24th of September is the standout. It’s your best shot by far. The morning brings a clean 7 ft swell from the NNW with a nice 12-second period, and light cross-offshore wind at 9 mph. The energy is strong at 2125. This is excellent for experienced surfers. The water temp is around 83° so it’s tropical, and that’s about average for this time of year. The afternoon gets even bigger, with a 16 ft NW swell, but that might be a bit much unless you’re really on it. Focus on that Thursday morning session. After that, the wind turns a bit messy again for the weekend, but the swell sticks around, just with a cross-shore wind.

So, the bottom line: it’s a long, quiet blank run until the 24th. That Thursday morning is the one to circle. The rest is either flat or blown out or too big. Forecasts can change, but right now, patience is the game for Tengan.

Stay safe out there.
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.
