The Lowdown

Alright, grab a coffee, I’ve had a look at the charts for Tengan. I’m not gonna lie, it’s a tough stretch ahead. The whole 16-day window looks like a write-off, so don’t be planning any trips just yet. The first solid recommendation doesn’t even pop up – in fact, there’s nothing worth paddling out for at all. We’ve got a long, empty gap of poor conditions from the start right through to the end of the forecast. For Tengan, this kind of blank run is more normal than unusual, so it’s not a huge shock, but it’s still a bummer.

Let’s break it down. The one spot on the radar is Tengan, a reef break that’s inconsistent and only really works for beginners. The water’s sitting at 83°F, which is about average for this time of year, so no thermal shock there.

Monday the 24th kicks off with some clouds and a gentle breeze from the east, but it’s onshore. We’ve got a tiny 2ft to 3ft swell from the ESE with a long 16-17 second period – that’s groundswell, but it’s weak, with combined energy values of 240 and 592 (moderate). The wave comment says “poor surf conditions” and the score is a flat zero. Not worth a second look.

Tuesday the 25th gets a bit bigger with a 10ft to 12ft swell from the ESE/E, but the wind swings north and gets cross-shore, blowing 15 to 22 mph. The combined energy rockets up to 4980 and 5733 (strong), but the wave state is described as “marginal surf forecast or questionable tide conditions” with a “moderate cross-shore with a cross-chop”. That’s messy, not clean. For a beginner spot, this is too big anyway.

Wednesday the 26th is a complete mess. Morning brings an 18ft swell from the NW with a short 9-second period, but the wind is howling from the west at 37 mph – that’s near-gale force and offshore, but the comment says “near gale offshore and very hard to paddle into.” The energy is 5746 (strong), but it’s dangerous and unsurfable. Afternoon drops to a pathetic 2ft from the east, with a south-west wind at 37 mph cross-offshore. Energy drops to 93 (weak). Still a zero.

From the 27th of August through to the 8th of September, it’s a relentless parade of poor surf conditions. You’ll see small swells, mostly under 4ft, with short periods (6-10 seconds), and winds are almost always onshore or cross-onshore, often fresh to strong. The combined energy rarely gets above 200 (weak). There’s a brief moment on Monday the 31st of August where the swell bumps up to 7ft to 7ft from the ESE with a 9-second period and energy around 658 to 750 (moderate), but the wind is onshore from the east at 15 mph, and the wave comment is still “poor surf conditions.” Same story on Tuesday the 1st of September: 10ft to 13ft from the east with cross-onshore winds, but the quality is shot – “moderate cross-onshore and choppy.” Too big for beginners, too messy for anyone else.

Later in the second week, it just fades into weak, blown-out dribble. The best you’ll see is on Monday the 7th of September afternoon – a 4ft swell from the east, 8-second period, with a light cross-offshore breeze from the south-west at 12 mph. The comment says “clean,” and energy is 177 (weak). It’s the least bad of a bad lot, but still a zero score. Not worth a paddle.

Honestly, there’s nothing here. No standouts, no hidden gems. The whole set-up looks more interesting for kite surfing than paddle surfing if you’re into that, but for surfers? Save your energy. Forecasts can change, but for now, it’s a solid pass.

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.
