The Lowdown
G'day, Rusty here. Look, I've got to be straight with you—this stretch is a tough one. We're looking at Tengan, a reef break, but the whole 16-day window is a write-off for any decent surf. It's a bit of a bummer, but it happens.
Let's run through it. The first week is a total dud. From Sunday the 19th right through to Saturday the 26th of July, the swell is tiny, barely pushing 1ft to 1ft from the east and southeast. The energy is weak as, with combined energy values down between 7 and 27. You'd be floating around more than surfing. The water is sitting at 82°F, which is a bit colder than normal for this time of year, so that's something to note. There are some glassy moments on the 23rd, but with no swell, it's just a flat, pretty lake.
Things get a bit spicy in the second week, but not in a good way. On the 26th of July, there's a hint of a pulse, with a 3ft southeast swell at 14 seconds (a moderate energy of 358), but it's onshore and messy. Then on the 27th, we get a 5ft groundswell from the southeast, period hitting 15 seconds. The energy jumps to 1093, so there's power. But the wind is a 9 mph cross-on, and it's choppy. Plus, the swell direction is southeast, and Tengan really wants it from the northeast. That combo means it's not going to line up well.
Later in the week, it gets wild. The 28th of July brings a 15ft southeast swell with a 15-second period and a massive 7839 energy reading. That's a lot of water moving. But the wind is a nasty 34 mph cross-on from the northeast, and it's a stormy mess. That's expert-only territory, and even then, the wind will ruin it. For the rest of the run into early August, we get clean offshore winds (WNW to W at 19-43 mph), but the swell is almost non-existent except for a few pulses of 3ft to 4ft groundswell from the east. The energy is there (536 to 755), but the wind is so strong it's a gale-force offshore. That makes paddling out a nightmare, and the waves would be impossible to get into.
So, the bottom line: there are no good surf options in this 16-day window. Tengan is inconsistent at the best of times, and this forecast is a blank run. It's more normal for this area to have quiet spells like this, so don't lose hope. Forecasts can change. For now, leave the board at home.
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.
