Table - best surf conditions forecast for Tengan over the next 16 days.
Alright folks, let me tell you what we’ve got lookin’ at us for Tengan over the next couple weeks. I’m not gonna lie to you, it’s pretty grim for a while. The first week and a half is mostly a write-off, with a lot of strong wind and tiny or no surf.
We start off with Saturday the 11th and Sunday the 12th – just brutal. Severe gale to gale force cross-onshore winds, totally blown out. Nothin’ doin’. Monday the 13th through to Friday the 17th, we’ve got tiny waves, mostly 0.3ft to 1ft. The wind does ease, and we get some glassy moments on the mornings of Thursday the 16th and Friday the 17th, but the ocean’s nearly flat. The combined energy is single digits or low twenties (0 to 22). Hardly worth paddlin’ out.
Now, things finally change come Sunday the 19th. We see a pulse of swell arrive. It’s still not clean on account of a moderate onshore breeze, but the size jumps up. Sunday morning we’ve got 7ft from the southeast with a 9-second period, and the combined energy climbs to 753 – that’s a moderate, proper push. This is the best on offer for the whole outlook. It’s a little lumpy and onshore, but for Tengan, which is a reef break that likes swell from the northeast (that’s its optimum direction), this southeast swell is a bit off-angle. Still, 7ft is solid, so experienced surfers can have a crack.
After that, Monday the 20th drops a little, 4ft to 4ft from the east-southeast with a short 7-second period and energy around 131. Then Tuesday and Wednesday the 21st and 22nd get small and blown out again with fresh to near gale onshore winds.
Then we get one more interesting day: Thursday the 23rd. We see 5ft from the east with a nice 13-second period, pushing the combined energy to 808. That’s a quality groundswell, but the wind is a strong cross-onshore, messin’ it up. From Friday the 24th onwards, it drops back to small, clean but tiny stuff with minimal energy.
Honestly, the standout window is Sunday morning the 19th. It’s not perfect, but it’s the only time we get decent size. For the rest, you’re better off waiting for the next forecast.

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.
