The Lowdown

Alright, this is a tough one to call. I’ve been staring at the charts for Tengan, and honestly, it’s looking pretty bleak for the next 16 days.

We’re looking at a real dry spell here. For a spot that’s a reef break and pretty exposed, the wave energy just isn’t showing up. The water temp is sitting about average for this time of year, so that’s not giving us any tricks either. For most of the first week and beyond, the wave energy is weak, with combined energy values mostly in the low two-digit to low three-digit range (like 61 to 420), but the real kicker is that the wind and weather are just making a mess of things.

Let’s walk through it. Saturday the 5th has a bit of size in the morning, with a 7ft NW swell, but that’s coming with a 30 km/h cross-off wind that kills any quality. The energy reads 959, but it’s called “marginal” at best. That same afternoon, it drops to 4ft with a cross wind and a risk of thunderstorms—total write-off.

Sunday the 6th through the rest of the first week is just a parade of poor conditions: cross-on winds, cross-chops, and swell periods as short as 6 to 9 seconds. That’s windswell territory, and it’s not going to hold a shape on a reef like Tengan. The combined energy is moderate at best (131 to 420), but the “poor surf conditions” tag on every single session says it all.

The second week doesn’t offer any hope. From the 12th onwards, the swell drops to tiny 1.0ft to 1ft, with very long periods (14 seconds) on the 12th and 13th, which is a groundswell signal, but there’s almost no height to push it. By the 14th, we see a little bump back to 3ft, but it’s short-period (8 seconds) and cross-on. The energy is weak to moderate.

There’s a pulse on the 15th Tuesday morning—6ft of ESE swell at 10 seconds, with combined energy jumping to 652—but it’s blowing onshore at 30 km/h, so that’s going to be a choppy, blown-out mess. Not for paddling. If you’re a kite surfer, maybe that setup looks more interesting, but for a surfboard, it’s a no-go.

The last few days, from the 17th to the 20th, fizzle out completely. Glassy conditions pop up on the morning of the 20th, but with a 0.7ft ENE swell at 10 seconds and combined energy of just 13, there’s literally nothing to ride.

So, what’s the standout? Hard to pick one. Honestly, there isn’t a single good session in this whole 16-day window. The best you could hope for is maybe a very early paddle on Saturday the 5th morning, but even that’s a reach with that wind. This is one of those blank runs where the area just isn’t firing. Nothing to get excited about, folks. Forecasts can change, but for now, save your 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.
