The Lowdown
Right, well, there ain't much on the menu comin' up for Tengan, and that's a bit of a bummer, hey? It's a reef setup over here, and it's inconsistent by nature, so when it's flat, it's flat. The next 16 days are gonna be a real test of patience. For the first solid week and a half, from Saturday the 25th of July right through to Monday the 3rd of August, it's lookin' pretty grim. The combined swell energy is super weak, sittin' in the low double digits (14 to 92), and it's just not enough to get excited about. We're starin' at a long blank run of poor surf and very ordinary conditions. It's a bit of a drought, but that's the way it goes sometimes around here.
Now, there's a bit of a glimmer of hope way out there in the second week. It's a long-range call, so don't go planning your life around it yet, but keep an eye on the 3rd of August. Monday afternoon sees a pulse of new swell rollin' in from the east. We're talkin' a 2ft east swell with a pretty long period of 13 seconds, which is a groundswell. The combined energy bumps up to 166 (moderate), and the wind goes glassy with an east-northeast breeze. It's the first time we've seen a score above zero, and while it's only "surfable waves but very ordinary conditions," it's a step in the right direction.
If that swell holds, Tuesday the 4th of August is the real stand-out, and it's the best on offer. The swell jumps to 4ft to 4ft from the east, and the period stretches out to 16 to 18 seconds – that's some serious long-period energy. The combined energy roars up to 651 on Tuesday morning and 889 in the arvo (strong to very strong). Now, this is a reef break, and a long-period east swell like this is exactly what it wants. The water temperature is about average for the time of year. The only catch is the wind. Tuesday morning has a 15 km/h east-southeast onshore breeze, and the afternoon has a 10 km/h southeast cross-on. It's not ideal, but for a reef, it might still be clean enough. This is expert territory though, with the swell over 5ft.
Wednesday the 5th and Thursday the 6th of August keep the swell goin' strong, with 5ft to 6ft from the east and east-northeast, and periods of 17 to 19 seconds. The energy is huge, hitting 1512 to 1910 (very strong). But the wind stays cross-onshore, which is gonna mess with the surface. The size pushes it into expert-only zone. It's a lot of power, but the wind is the enemy here.
After that, the swell backs right off again on Friday the 7th of August, droppin' to 2ft and then 3ft with short period junk, and it's back to poor conditions. The run ends with a whimper.
So, bottom line: it's a long wait. The only real chance for a decent wave is on Tuesday the 4th of August, with that big, long-period east swell. Don't get your hopes up too much for the rest of it.

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.
