The Lowdown

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 gotta be straight with you – this is a tough one. The forecast is looking pretty grim for the entire 16-day window. We’re looking at a long, dry spell with barely a ripple to get excited about. The first few days are a total write-off, and honestly, it doesn't get much better after that.

Starting off on Monday the 20th of July, we’ve got tiny 0.7ft swell from the east with a period of 10 seconds. The water is sitting at 83°, which is about average for this time of year, but that’s the only thing that’s normal. The wind is a cross-offshore, but with no swell, it doesn’t matter. The combined wave energy is a measly 10 – that’s weak, real weak. We’re calling it “poor surf” and it’s a score of 0.

Tuesday the 21st and Wednesday the 22nd are much the same story. Swell bumps up to a tiny 1ft, periods around 9 seconds, and the energy is still pathetic at 15-16. Winds are light and cross-off, but there’s just nothing to ride. Thursday the 23rd stays flat with 1ft and a 10-second period, though we do get a moment of glassy conditions Thursday afternoon. Still, with 20 energy, it’s not enough to paddle for.

Friday the 24th through Sunday the 27th of July is a mess. The swell is still tiny, but the wind swings onshore, and by Sunday we’ve got a 3ft to 3ft windswell from the east with a terrible 4-second period. That’s just a bumpy, choppy mess with 30 energy – not for surfing, maybe interesting for a kite if you’re into that, but for a paddle surfer? Hard pass.

The rest of the week into the start of August is more of the same – flat, onshore, or just plain ugly. There’s a brief moment on the 30th of July where we get a 0.7ft with a 12-second period and offshore wind, but the energy is only 10. It’s clean, but there’s no wave to surf.

The only faint glimmer comes on the 1st of August, Saturday afternoon, when a 0.7ft swell from the east jumps to an 18-second period, pushing the energy to 37. That’s a long-period groundswell, but it’s tiny. Then on Monday the 3rd of August, we see a 1ft swell from the east-northeast with a 16-second period and energy hitting 50 to 53. Still, it’s only 1ft. For a reef break like Tengan, a long-period groundswell that small might just break straight and not offer much shape. The wind is onshore, too, so it’s not looking clean.

So, to be honest, there’s nothing here to recommend. There are no standout days, no hidden gems. It’s a blank run. The guidance shows Tengan is an inconsistent, beginner-friendly reef that needs a northeast swell, and we just aren’t getting it. This is a normal dry spell for this area – sometimes the ocean just shuts off. Keep your eyes on the charts, but for now, leave the board in the shed.

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.
