The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you – it's gonna be a long, flat spell. We're looking at a real quiet stretch for the next week or so at Tengan. The tiny bumps that show up are barely making a whisper, with combined energy sitting at a measly (7) to (40) for most of it. It's all small, weak stuff, and even the cleanest windows won't give you a ride worth paddling for. You'll see a few glassy moments on the morning of the 22nd of July, and then again on the afternoon, with the wind going totally light, but with only 0.7ft of swell, it's just a lake. We're talking at least a solid week of nothing to write home about.
Hang in there, because things might start to look a little more interesting right at the end of the run. Towards the end of the month, around the 27th and 28th of July, we finally see a pulse of energy pushing through. The swell height ticks up to 1.0ft, but more importantly, the wave period extends out to 13 seconds. That's a proper groundswell window, and the combined energy jumps to (48). For a spot that's been snoozing, that's a significant change. The direction is straight easterly, which is a bit off the optimum for Tengan (they like it from the NE), and the wind is looking onshore, so it won't be perfect. This is a long-range hint, so keep your fingers crossed, but it's the only light at the end of the tunnel. For now, save your energy and wax.

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.
