The Lowdown
Alright folks, Rusty here. Gutting news for Tengan – there’s absolutely no surf worth paddling out for in the entire 16-day window, from July 16 through July 31. This reef break is already an inconsistent beginner spot, and the forecast just confirms it’s staying flat or messy.
Through the first week and a half, you’re looking at tiny 0.7ft to 2ft east-southeast swell with short periods – combined energy barely reaching 111 (moderate) at best. The wind? Mostly cross-off or cross-on, but even when it’s offshore it’s not enough to make a wave out of that much nothing.
Then come July 27 and 28, the swell jumps dramatically – 6ft to 16ft from the southeast with long 14‑ to 16‑second periods – but it’s accompanied by strong onshore winds from the east and southeast at 15 to 22 mph. That’s a massive 10352 combined energy reading, but it’s just big, messy, onshore chop. Perfect for kitesurfing, maybe, but for a traditional surfboard? No chance.
The optimum swell direction for Tengan is northeast, and we’re getting nothing close to that. Crowds? Sometimes it can get busy, but with no waves it’ll be empty. Water temp? No anomaly data, so assume average for the time of year.
Look, it’s a rare blank stretch for this area, but forecasts can shift. Keep an eye on 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.
