The Lowdown
Alright, Rusty here, talkin' Tengan. Let's cut to the chase.
The next ten days or so are a total bust. We're looking at piddly little 1ft waves, with combined energy barely hitting 20 (16 to 20). It's just weak. The wind's all over the place, but it doesn't matter when there's nothing to push. Don't even think about paddling out.
Now, fast forward to the start of August. That's the window. On Sunday, August 2nd, a real groundswell rolls in. We're talking 5ft to 5ft from the ESE with a 15-second period. The energy jumps to 936 to 1045 – that's moderate to strong. The wind is light and offshore to cross-off from the NNW and NW. That'll keep the reef at Tegan glassy and clean. That's the standout. It's a long wait, but it's worth it.
Monday, August 3rd, gets even bigger, with 7ft to 8ft swell from the ESE and E, still with that long 15-second period. The energy is massive, hitting 2043 then 3309 – that's strong to very strong. But the wind goes cross-shore, and that size is for experts only. The tide might mess with the lineup too.
The water's a warm 83°, which is pretty average for this time of year.
So, forget the near future. Your best bet is Sunday, August 2nd, for the cleanest, most manageable waves. Monday the 3rd is for the brave and the skilled.
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.
