Alright, Rusty here. Let's have a look at what's cookin' for Tengan.
Honestly, it's a pretty quiet start for the next week or so. We've got a solid run of small, weak, and just poor surf conditions through the weekend and into the start of next week. The swell energy is barely registering, with a combined energy of just 25 (weak energy) on Friday the 3rd of July, and it only gets smaller from there. The wind is mostly a light cross-offshore, which would be nice if there were any waves to ride. It's a real frustrating stretch of flatness.
Monday the 6th of July afternoon sees the period jump to 15 seconds, suggesting some long-period groundswell energy is starting to trickle in, but the height is still only 1.0 feet with a combined energy of 43 (weak energy), so it's not doing anything. A real teaser.
The Standout Window: Okay, pay attention now. Tuesday the 7th of July is the one to circle. The morning shows a clean 3 feet swell from the ESE with that long 15-second period and a combined energy of 503 (moderate wave energy). The wind is a light cross-offshore. Then, Tuesday afternoon looks like the absolute peak. The wind goes glassy, and the swell builds to a clean 4 feet from the ESE with an incredible 18-second period. The combined energy jumps up to 1118 (moderate wave energy). This is the best on offer. For an inconsistent reef break like Tengan, getting a window of clean, glassy, groundswell is a rare treat. That 18-second period means proper, powerful lines. It's not huge, but perfectly manageable for a broader range of surfers—not beginner small, but not gnarly either. Tengan, being a fairly exposed reef, should handle that long-period energy beautifully, giving some nice, well-shaped walls. Just be aware that it's an inconsistent spot, so you might have to be patient between sets.
Wednesday the 8th of July morning is still pumping with 7 feet of that long-period swell, but the wind swings onshore from the NE, making it choppy. That one is for experts only if you go out, as it'll be a difficult, bumpy mess. It gets worse from there. By Thursday and Friday the 9th and 10th, the swell is massive (over 12 feet) but the wind is howling onshore or from the east. Those days are blown out and dangerous—a kite surfer's dream, not a paddler's. We then hit another quiet spell from the 11th of July through the end of the forecast.
So, bottom line? If you can get to Tengan on Tuesday the 7th of July, you’re golden. That afternoon glass-off is the one. After that, we’re back to waiting.

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.
