The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at the surf outlook for Tengan. I’ll be straight with you – the next couple of weeks are a real mixed bag, with a long, quiet stretch before things get seriously big and wild.

Right now, and for the rest of July, the surf is basically a no-go. We’re looking at tiny, weak waves. For the first week, from Saturday the 18th right through to the end of July, the swell is mostly 0.3ft to 1ft from the SE or E. The combined energy is pitiful, sitting between 3 and 40 (weak energy). It’s labelled “poor surf conditions” across the board. There’s just no power to work with. You’ll see a few nice mornings with glassy conditions, like Wednesday the 22nd and Thursday the 23rd, but with nothing to ride, it’s just a flat, pretty ocean.

Then, things take a turn for the angry. From the 28th of July, the wind really fires up. We get a strong cross-onshore blow from the ENE, ramping up to gale force by the 28th, with 5ft swell but messy, blown-out conditions. The energy picks up to a moderate 609, but the quality is zero. Into the 29th and 30th, the wind swings offshore from the WSW, but it’s storm force – 50 to 60 mph. The swell builds to 5ft, and the energy is strong (766 to 1162), but it’s completely unsurfable. You’d be mad to paddle out. This setup is more interesting for kite surfing than paddle surfing.

The real standout, and the only one worth your time, is at the very end of the forecast. On Saturday the 1st of August, Tengan (a reef break that’s inconsistent and best for beginners) starts to pump. The swell jumps to 15ft from the N, with a very long period of 13 seconds. The combined energy is a massive 6926 (very strong wave energy) in the morning, building to 8700 in the afternoon. It’s a groundswell, and with that long period, it will be better-shaped with more energy, but it might break a bit straight at this reef setup. The wind is strong offshore from the WNW, keeping it clean, though paddling out will be a mission. This is big, powerful stuff – over 8ft, so it’s only for experts. The rating for the morning is a 4/10, but by the afternoon with a fresh offshore breeze, it hits a 6/10, and conditions are described as “excellent for experienced surfers.” It’s a long way off, so treat it as promising but not locked in.

Then on Sunday the 2nd of August, we’ve got 12ft from the NNW with a moderate offshore wind, and the energy is still huge at 4011. Still big, still clean, but still only for the experts.

So, the best on offer is clearly the 1st and 2nd of August. A massive, long-period groundswell with clean, offshore winds. It’s a proper event, but it’s not for the faint of heart.

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.
