The Lowdown

Alright, Rusty here. Let's have a look at what’s cooking for Tengan.

First up, this is a reef break that’s inconsistent and pretty exposed to the swell, but it needs the wind to play nice. Unfortunately, we're looking at a long, frustrating stretch of onshore and cross-shore winds that are going to trash the waves for the better part of a week. From Monday the 17th right through to Sunday the 23rd, it’s mostly poor surf conditions, with sloppy, choppy lineups and not much height. The combined energy is often weak (30 to 65 range) and the swell is short-period, so you’re not getting any real push. It’s a frustrating start.

Then, on Monday the 24th, things finally turn. We get a gorgeous shift: glassy conditions, the wind goes light, and a long-period groundswell arrives from the ESE at 16 seconds. The combined energy jumps to 164 in the morning and 375 by the afternoon. The wave height is only 3ft in the arvo, but that long period means it’ll have some real grunt for a reef. This is your first true standout. The water temp is pretty average for the time of year, nothing unusual.

The standout window really lights up on Monday the 24th afternoon and into Tuesday the 25th. That 16-second groundswell pushes the energy up to 822 on Tuesday morning, with 4ft surf. Wind stays light, mostly cross-shore, but it’s clean enough. The big issue is that this is an inconsistent spot, and with long-period swell at a beach or reef setup, it might not be the best shape for everyone. Still, if it lines up, Tuesday is the pick of the first week.

From Wednesday the 26th through Friday the 28th, the swell builds more. Heights hit 5ft to 7ft, with strong energy readings (1230 to 2107). The wind goes cross-offshore and then clean offshore on the 28th, which is prime. But the forecast notes “marginal surf forecast” each day, so there’s a tide or quality issue that might hold it back. Still, Friday the 28th afternoon with offshore wind and 7ft from the east is worth a look for anyone who knows the reef.

Now, the real monster shows up on Saturday the 29th. The morning has 12ft from the east with huge energy (9215), and by the afternoon it’s a staggering 25ft from the north with energy over 17500. The period drops to 11 seconds, so it’s a big, powerful swell. This is for experts only – 25ft is no joke, and even the 12ft morning is too big for most. The wind is cross-offshore, keeping it clean. If you're a charger, this is your standout, but be warned: this break is inconsistent, so when it fires this big, it’s a rare beast. It’s also the sort of day where, with that power and size at a reef, it could be more of a tow-in or even a kite-surfing setup if the shape gets too gnarly for paddle.

After that, the surf drops back to nothing really. Sunday the 30th has a glassy morning with 2ft, but it’s not worth paddling out for. The rest of the run has onshore winds and weak, short-period swell. The forecast ends on a flat note.

So, your best bets: Monday 24th afternoon for a clean, long-period ride if you can handle the inconsistency, and Friday 28th afternoon for solid overhead waves with offshore wind. The 29th is a massive, expert-only event if you’re keen on a real adrenaline hit.

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.
