The Lowdown

Alright, Rusty here again. Let's talk about what's coming up for Tengan.

First up, the water is sitting at 86°, which is a touch warmer than what we’d usually expect for this time of year. Not a massive shift, but noticeable.

Honestly, the next couple of weeks look pretty grim for getting a decent wave at Tengan. The only real flicker of something happening comes early on Monday morning, August 3rd. We’ve got a small 3 ft swell from the east, with a super long 15-second period. The combined energy is weak, sitting at 369. It’s a groundswell, which means clean lines, but it's small and the wind is a light cross-shore. It’s surfable, but it’s marginal. The afternoon holds the same size with a slightly longer period, but the wind is still cross. It’s not great.

Things take a turn for the worse from Tuesday, August 4th onwards. The swell picks up, but the wind swings cross-onshore and gets messy. By Wednesday, August 5th, the swell is up to 6 ft from the east, but the wind is a choppy cross-onshore, so it’s a bumpy mess. The energy is building (2014), but it’s not clean surf.

The real excitement, and the only standout in this entire run, is a massive spike on Friday, August 7th. The swell gets absolutely hammered by a storm, rising to 26 ft from the NNW. The wind is a clean cross-offshore but it’s a storm force 56 mph blow. The combined energy is a massive 24983. The period is a shorter 12 seconds, so it’s a windswell. This is a big, dangerous, and powerful wave. The forecast even says it’s too big for this break. This is expert-only territory, and even then, it’s a dicey prospect. The afternoon gets even crazier with 38 ft swell and hurricane-force winds. This is less a surf session and more a survival exercise.

After that peak, the swell drops off a cliff. Saturday morning, August 8th, sees a tiny 2 ft swell from the NNE with clean offshore winds, but the energy is only 180. It’s a tiny clean wave, nothing to get excited about.

From Saturday afternoon all the way through to the end of the forecast on August 18th, it’s a dead zone. Cross-shore winds, onshore winds, hurricane-force southerlies, and flat spells with zero swell energy. There are a few days with a tiny 1 ft or 2 ft swell, but with poor wind and conditions, it’s not worth a paddle. The surf is just not on.

So, in short: the only real event is the massive, dangerous, and unsurfable swell on Friday, August 7th. Everything else is flat or blown out. It’s a blank run for Tengan.

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.
