Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.
Right off the bat, I’ll be honest with you – it’s a tough stretch. The whole 16-day window is looking pretty flat for Tengan. We’re staring down a long run of tiny, weak waves and mostly poor surf conditions. The first real recommendation doesn’t show up until Wednesday the 15th, and even then it’s only tiny. There’s a big gap of nothing before that.
That first glimmer comes on Wednesday morning, July 15th. We’ve got a small 0.7ft swell from the east with a period of 9 seconds, and the combined energy is a weak 11. The wind is a light cross-offshore from the southwest, which is a nice change. It’ll be clean. By Wednesday afternoon, it bumps up slightly to 1.0ft from the east-southeast, with a period of 11 seconds. The combined energy is still just 36, and it’s clean again with a gentle cross-offshore breeze. It’s not going to be any kind of standout session, but it’s the closest we get to a clean wave.
Thursday the 16th and Friday the 17th are similar but even smaller. Thursday morning has 0.7ft east swell with a 9-second period and a clean offshore wind from the west-southwest. By Friday afternoon, we’re still looking at 0.7ft east swell, a 10-second period, and light offshore winds. Combined energy never gets above 10. It’s clean, but there’s just nothing to surf.
The only real bump in energy happens around Sunday the 19th of July. The swell lifts to 2ft from the east with a 10-second period, and the combined energy hits 96. That’s the most oomph we see in the whole period. But here’s the kicker – the wind is cross-onshore and then onshore, so it’s going to be choppy and messy. The water temp is sitting at 84°, which is right on average for the time of year, so no surprises there.
Because this is a reef break, and it’s inconsistent, and the swell is tiny, the whole setup is a bit of a buzzkill. The larger, more energetic swell that arrives around the 23rd of July (2ft, 11-second period, combined energy 115) is still ruined by onshore winds. Nothing here is shaping up for a proper paddle session.
So, plain and simple: there are no good surf options in this 16-day window for Tengan. The tiny, clean windows on Wednesday through Friday are the best bet, but only if you’re desperate. It’s a blank run, and that’s pretty normal for this area. Forecasts change, but for now, leave the boards 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.
