The Lowdown

Alright folks, Rusty here. Let’s be straight with you. It’s a bit of a tough stretch ahead for Tengan. We’ve got a lot of swell on the way, but the winds and conditions are going to be fighting us for most of the next two weeks. Don’t get too excited about the size—it won't be clean.

The whole window starts off slow, with only knee-high dribble through the 31st and into the 1st. There’s a bit of energy tryin’ to build, but it’s just not there. Saturday morning you’ll find clean, but tiny waves. The wind is light, so it’s a good time for a paddle, but not much more.

We finally see a pulse arrive on Sunday the 2nd, with waves building to 2 ft. The energy is still weak, only registering at 165, but it’s a start. A few small, clean waves are rideable, but you’ll be working for them. Still, the light, cross-off wind leaves things tidy.

Monday the 3rd, we get a little more push into the 3 ft range with moderate energy (294). The morning clean, but as the day goes on, a cross-breeze kicks up and messes with the surface, making it a bit grovelly.

The real size shows up on Tuesday the 4th, with waves pushing up to 4-5 ft and energy jumping big time (over 1080-1431). The wind is mostly cross-off to cross-on though, and with the chance of storms, the surface is pretty ordinary. It’s a bit of a funky day. If you’re a beginner, this size is getting to your limit.

Then things go a little sideways. Wednesday the 5th sees bigger surf, up to 7-8 ft, and the wind picks up strong, making it lumpy and choppy. Not great. This is followed by a proper pulse of swell on Thursday the 6th, with massive 15 ft waves and energy readings through the roof (over 15,000-18,000). But hold your horses—the wind is screaming near gale force. It’s a complete mess and dangerous for anyone. Not a paddle.

That storm doesn't want to quit. Friday the 7th brings storm-force winds over 62 mph, and while the swell is still solid, it’s pure chaos. By the afternoon, the swell drops right off. The tail end of that system on Saturday and Sunday leaves behind some long-period energy, but the wind is howling out of the south, creating a severe gale with big, messy cross-shore waves. Total write-off.

The beginning of the second week finally lets things settle a bit. From Monday the 10th, we see waves in the 2 ft to 3 ft range, but it’s still sleepy and cross-shore winds keep it messy. The next few days are marginal, with short-period chop and nothing exciting.

Midweek, the 13th and 14th see conditions trying to turn onshore. A new, weak, and short-period swell shows up around 3 ft on Friday the 14th, but the onshore wind kills any chance of it being clean.

To close out, the 15th brings a small, short-period swell up to 4 ft, but the wind is cross-on. It’s a frustrating pattern, more about fighting the elements than getting a good wave.

Look, the standout here isn't a perfect day, it's the clean, small windows early on. Sunday morning the 2nd, with light winds and rideable, clean lines at 2 ft, is as good as it gets. The energy is weak (165), but it’ll be the most user-friendly surf. Also worth a look is Tuesday morning the 4th, when we have 4 ft waves and still light, cross-off wind, making for some fun, clean, and punchier waves. But with the risk of storms, it’s a gamble.

Overall, this run is more about reading the conditions and being patient, with a couple of short windows of clean surf before the weather turns on us.

Rusty out.

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.
