The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve scanned the charts for our stretch of coast, and it’s a bit of a heartbreaker. We’ve got a long, long window of flat and messy conditions ahead, and only a couple of fleeting moments that will get you even slightly excited.
The whole 16-day stretch is a real test of patience. The water is a touch warmer than normal for this time of year, which is something, but that’s about the only highlight for a while. We start off with tiny, weak surf that’s barely a ripple, and we’re looking at a run of poor, ordinary, and marginal days that just seem to blend together. The first week is a write-off for any decent waves. A few of these pulses get close to 3 feet but they’re crossed-up and junky, not worth paddling out for.
The big drama hits on the 7th. A massive swell shows up, absolutely ripping, but it’s way too big for this break. We’re talking 39 feet of raw power with a gale-force cross-shore wind. That’s not a day for surfing; that’s a day for watching from a cliff and thanking your lucky stars you’re not out there.
After that monster, the ocean spends the rest of the outlook trying to settle. The 8th is a complete washout with hurricane-force winds, and things stay messy for the next several days. There’s a brief moment on the 9th afternoon and the 10th morning where the wind goes offshore and blows the surface clean, but the swell’s gone. It’s just small, stormy leftovers, not enough to ride. That long, empty gap runs right through until the middle of the month. The 12th and 13th have a slight lift to maybe 2 feet but it’s weak and the periods are short, so it won't have any push.
The only real standout, if you can call it that, is a promise on the 10th. That’s a full week away, so we’re just talking about potential here, not guarantees. For that day, there’s a forecast for a 4-foot east swell with a decent period and a strong offshore wind. That should clean things up nicely after the storm, making Tengan (Tengan) look like a proper point break. The swell direction is right in that NE window the spot loves, and the energy readings are moderate. But remember, this place is inconsistent and it’s a beginner reef break, so this is still a fickle promise. That’s the one you’d circle on the calendar, but only if you’re flexible and willing to take a gamble.
Other than that burst, there’s a couple of days around the 15th and 16th with a clean, cross-off breeze, but the swell is tiny and weak, with periods of 6 seconds, which isn’t worth the paddle. The overall energy in the water is just anemic. It’s a rough stretch, my friends. Patience, and a lot of checking the forecast, is the name of the game.

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.
