Alright, Rusty here. Let’s talk about what’s cookin’ for Tengan.
Right off the bat, Tuesday afternoon is your only real window in the whole 16-day run, and it’s a beauty. We’ve got a clean 3ft swell coming from the ESE, with a long 16-second period – that’s proper groundswell energy, and the wave energy is sitting at a solid 519 (moderate). The water is 83°, which is pretty much right on the money for this time of year, no weirdness there. And the wind? Glassy, mate, from the WNW at just 3 mph. That reef setup at Tengan will be smooth as silk. It’s a beginner-friendly wave, but it’s inconsistent, so don’t expect a wave every minute. For that one afternoon, it’s about as good as it gets here.
After that, it’s a long, grim stretch. Wednesday the 8th, the swell jumps to 5ft, but the wind swings to a cross-onshore NE at 9 mph, making things choppy. By Wednesday afternoon and right through the rest of the week, the swell builds way up – 10ft to 16ft – but it’s all onshore wind, gale-force at times, with thunderstorms. Combined energy hits 17078 (strong to very strong) on Friday morning, but that’s just raw, messy power. That’s kite-surfing territory, not paddle surfing.
We’ve got a total flat spell from Saturday the 11th all the way to Monday the 13th morning, with zero swell and blown-out conditions. Then from Monday afternoon through to the end of the forecast on the 22nd of July, we get tiny dribbles of surf – 0.3ft to 2ft – mostly with poor winds. There are brief moments of glassy conditions on the 15th and 19th, but the swell is just too small to bother paddling out for.
So, bottom line: Tuesday afternoon, 7 July, is your one standout. Get it while it’s glassy and clean, because after that, the coast goes quiet and angry for a long while.
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.
