The Lowdown

Alright, Rusty here, givin’ you the skinny on this stretch in feet and knots. Look, it’s a rough 16 days for Tengan. There’s a long dry spell, and only the very start shows any kind of glimmer, but it fades fast.

First thing Tuesday afternoon the 8th, we get a pulse at 7 ft from the NNW, but the wind’s a fresh 30 km/h cross-off. The energy’s middlin’ (593), but the call is poor. Not one to chase.

Wednesday the 9th sees the swell drop to 5 ft and then 5 ft from the north, but the wind is a cross-shore at 25 km/h, choppin’ it up. Energy’s in the 250-297 range. Still no good.

Thursday the 10th is the best of a bad bunch. Swell sits at 5 ft from the north, period around 9-10 seconds. The energy bumps up to 444-496, which is moderate. In the morning the wind dies to a light breeze at 10 km/h, and the surf is called marginal. There’s a tiny window for clean-ish waves, but something with the tide is wrong. It’s the only thing on the menu, but it’s a pretty sad meal.

From Friday the 11th, it’s all downhill. Swell drops below 4 ft, and by the 13th it’s a sad 1 ft with a long 14-second period, but the energy is weak (74), and it’s all blown out by cross-onshore winds. Water temp is a balmy 84°F, which is normal for the area.

The second week is a ghost town. From the 14th through the 23rd, the swell never reaches 2 ft, the wind is mostly onshore, and the energy readings are all under 120, in the weak zone. That glassy moment on Tuesday afternoon the 15th with 2 ft from the east is pretty, but the energy is only 90, and the wave comment is still “poor surf conditions.” Clean glass on nothing is still nothing.

Your only, and I mean only, standout is Thursday the 10th morning, with that north swell and light wind givin’ you a marginal shot. For the rest, leave the board at home. It’s a kite surfer’s dream for a few days, but for us, it’s a bust.

Rusty, out.

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.
