Alright, Rusty here, and I gotta be straight with you—this Tengan (Pitcairn Islands) outlook is a total dud for the next couple weeks.
We kick off on Sunday, July 12th with thunderstorms and a 35 km/h cross-onshore breeze. No wave energy at all, just a lumpy, messy scene. That sets the mood. Monday the 13th brings a tiny 0.1m to 0.5m swell with a short period and next to no power (2 to 7 energy). It’s hopeless. Tuesday the 14th isn’t any better. By Wednesday the 15th, the wind eases and the conditions clean up a little, but the swell is still only 0.3m and the energy is low (31 to 36). It might look pretty out there, but you’d be bobbing around on barely a ripple.
Thursday the 16th stays clean, and by Friday the 17th it’s totally glassy with zero wind and a tiny 0.2m swell—perfect surface, but no waves to ride. That’s the tease. Saturday the 18th sees a light cross-onshore breeze, still tiny. On Sunday the 19th, the energy finally climbs to 106, but the swell is only 0.7m and coming straight from the east with an onshore wind. Not good. Monday the 20th brings the biggest waves of the whole forecast—1.2m from the east, still onshore wind, energy at 277. But it’s all poor quality. The period is only 9 to 10 seconds and the wind is never right for this reef break. Tengan needs a northeast swell, and we’re getting east or east-southeast the whole time.
From Monday the 20th through Wednesday the 22nd, we get 1.2m to 0.8m from the east with moderate onshore wind and moderate energy (110 to 277). It’s all lumpy and messy. Then it fades fast into tiny 0.5m to 0.3m junk, and by Sunday the 26th, it’s completely flat.
The only standout—if you can call it that—is the glassy conditions on Friday the 17th, but with 0.2m of swell, you’re not surfing anything. The biggest pulse from the 20th to the 22nd is ruined by onshore wind. No water temperature anomaly is given, so I can’t say if it’s unusual for the season.
Honestly, there isn’t a single surfable session in the whole 16 days. If you’re into kiting, that onshore wind and moderate chop from the 20th to the 22nd might be your jam, but for paddle surfing, this is a long, dry stretch. Forecasts can flip, but right now, don’t bother suiting up.
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.
