G’day, Rusty here, and I gotta be straight with you—this stretch we’re looking at for Tengan is a tough one. We’ve got a big 16-day window, but there’s a serious dry spell to start. The first real chance to paddle out doesn’t pop up until the morning of Wednesday, July 9th, and even then, it’s a bit of a rough ride. The water’s sitting at about 83°, which is pretty much bang on average for this time of year, so no surprises there.

The outlook kicks off on Wednesday, July 8th, with some small, choppy ESE swell around 5 ft, but the cross-onshore wind is making it messy. It’s not worth your time. Thursday, July 9th, sees the swell jump up to 10 ft with a solid 16-second period, but the wind is howling onshore at 18-22 mph, and it’s just a total write-off for safe surfing. By Friday, July 10th, we get a massive pulse—20 ft of SE swell, and the combined energy is a whopping 22,897 (strong energy), but here’s the catch: the wind is screaming near-gale force from the east at 34 mph, and the waves are predicted to be too big for this reef break. This is expert-only territory, and even then, it’s borderline dangerous. The afternoon drops to 12 ft with a short 9-second period, but the wind is still up. Not a good look.

From Saturday, July 11th, right through to the morning of Sunday, July 20th, we’re in a dead zone. There’s a gap of about 9 days with no real surfable waves. The wind is a mess—gale-force cross-onshore to begin with, then easing to fresh breezes, but the swell is tiny, often under 3 ft, and the combined energy is mostly under 100 (weak energy). A few days, like July 15th and 16th, flirt with knee-high waves around 4 ft, but the conditions are poor. It’s a blank run, and for an area like this, it’s not that unusual—when the trade winds set in, it can get pretty quiet.

The one standout, and it’s a distant one, arrives on Monday, July 20th. The morning brings a clean 2 ft E swell with a 12-second period, and the wind is light and cross-offshore from the southwest at 6 mph. The combined energy is 172 (moderate energy), and while it’s not big, it’s the cleanest we’ll see. The afternoon gets even better: 3 ft with a light breeze from the southwest at just 3 mph, and the combined energy nudges up to 226 (moderate energy). This is your best bet—a small, glassy day at Tengan with peelable lines. The swell direction (E) isn’t a perfect match for the optimum (NE), but with the wind so light, it’ll still offer some fun, slow waves. It’s inconsistent here, so you’ll need patience, but the lack of crowds (sometimes) means you might have it mostly to yourself.

After that, it fades again. The 21st and 22nd are small and choppy, and by the 23rd, it’s back to tiny cross-shore slop. So, to sum it up: the window is mostly empty, but if you’re hungry, that Monday, July 20th, is the one to circle. It’s not a classic, but it’s clean and quiet.

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.
