The Lowdown

Righto, let’s have a look at what Tengan’s got cookin’.

To be straight with you, the next 16 days start off flat as a pancake. There’s a real gap here with no surf to speak of through the first few days. Sunday the 2nd and Monday the 3rd are barely a whisper, with swell under 3 feet and a weak combined energy of only 48. That’s not worth wetting a suit for. Tuesday the 4th shows a bit more push with 4 feet east swell and energy climbing to 1087, but the wind is cross and conditions are marginal. Not a standout.

Wednesday the 5th sees the swell bump up to 7 feet east at 18 seconds, which is a nice long period groundswell, but the cross wind is 16 mph and it’s lumpy. Energy is moderate at 2639, but it’s not clean. Then Thursday the 6th gets messy – 13 feet east swell but with a 34 mph cross wind making it a total no-go. Energy hits 14057, but that’s just power you can’t ride.

Friday the 7th morning is a real warning: 41 feet north-northeast swell, storm-force 59 mph cross-onshore wind. That’s dangerous, not surfable. The energy is 71657, which is extreme. After that, it’s a write-off for days. Saturday the 8th through to Monday the 11th are all poor, with onshore gales and messy surf. Even the calmest day in that stretch, Tuesday the 12th morning, has only 3 feet east swell and clean cross-offshore wind, but the energy is just 314 and the swell is weak.

The one true stand-out in this whole forecast is Tengan itself, but it’s not until Saturday the 15th morning. We get a clean 2 feet east-northeast swell, period 12 seconds, with a gentle cross-offshore breeze from the north-northwest. The energy is a modest 169, but the conditions will be glassy and clean. This is a beginner-friendly reef break that’s inconsistent and picks up east-northeast swell best. Crowds are possible here. Water temps are about average for this time of year. It’s not a big day, but it’s the only window where the wind and swell line up for a proper session. Everything before that is blown out or flat.

So, if you’re keen, pencil in that Saturday 15th morning. The rest of the run is a waiting game. Forecasts can change, but right now, it’s slim pickings.

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.
