Alright, let me break it down for ya. It’s Rusty here, and I’ve got the lowdown on the local waves. Look, straight up, it’s a pretty grim stretch ahead for Tengan. We’ve got a real long, dry patch before anything even vaguely rideable shows up, and even then, it’s not exactly gonna set the world on fire.
We’re looking at a big gap here. No real surf to speak of for the first few days. The only time we get any sort of pulse is on Monday the 6th of July into Tuesday the 7th of July. Monday afternoon is tiny, just ankle-snappers at 1ft from the ESE, but the wind is a light cross-offshore, so it’ll be clean. The energy is weak, only (102) in the water. The water temp is sitting at 83°, which is about average for this time of year, so nothing weird going on there. It’s surfable but very ordinary.
Then on Tuesday the 7th of July morning, it’s still small at 3ft and a bit cross, but Tuesday afternoon picks up to 3ft from the ESE with a nice long 16-second period. The wind swings light and cross-off from the NW, making conditions clean. That’s your best chance in the whole outlook, and it’s still nothing special. The combined energy jumps to (519), so there’s a bit more push, but it’s not a standout. It’s just… the least bad.
After that, it all goes south. From Wednesday the 8th of July, the swell starts to climb, but the wind turns nasty. Wednesday morning sees 6ft from the ESE (17-second period, very long), but it’s cross-on and messy (1533 energy). By Wednesday afternoon it’s 7ft but choppy. Thursday the 9th of July brings a 10ft swell from the SE with a 16-second period, but it’s totally blown out by a fresh onshore wind and risk of thunderstorms. The energy is massive at (3985), but it’s unsurfable. For a reef break like Tengan, that long-period swell might look good on paper, but with that wind, it’s a no-go. And a 10ft wave? That’s expert-only territory anyway, but the conditions are just vile.
Then we hit a wall. From Friday the 10th of July all the way through to Monday the 20th of July, the forecast is just poor. We’re talking days of onshore gales, risk of thunderstorms, and tiny, weak swell or no swell at all. The energy values are pitiful, often below (100). There’s a few days of 0.7ft to 2ft slop. There’s a brief moment on Saturday the 18th of July morning where it’s clean with a light cross-offshore from the SSW, but the swell is only 2ft from the E, so it’s pretty much a flat day.
In short, the only window that’s even worth paddling out is Monday the 6th afternoon and Tuesday the 7th afternoon. The rest of the 16 days is a write-off. For a spot that’s inconsistent, this kind of blank run is more normal than you’d hope. Don’t hold your breath; forecasts can change, but right now, it’s looking very 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.
