The Lowdown

Alright folks, Rusty here. Let’s just get it out there – the next couple of weeks are gonna test your patience if you’re looking to paddle out at Tengan. We’ve got a long dry spell with barely a wave worth mentioning for the first ten days. The whole opening stretch from the 7th right through to the 19th is a write-off. Poor surf conditions day after day, cross-shore and onshore winds, and a lot of unstable weather with risk of thunderstorms. The swell stays weak and short-period, mostly around 3 ft to 6 ft, but the wind just ruins any chance of a clean wave. The combined energy is low to moderate at best, topping out around 505 on the 7th, but with that NNW wind howling at 19 mph, it’s just messy. Water temp is sitting at a warm 84°F, which is about average for this time of year, so no surprises there. For a beginner-friendly reef break that’s already inconsistent, this is a tough run.

Now, if you can wait, things start to look a little more interesting right at the end of the window. Monday the 21st of September finally brings a pulse of energy. We’re looking at a 6 ft to 7 ft swell pushing in from the NNE and NE, combined energy jumping up to 908, and the winds go light and cross-shore. That’s the best we’ll see – clean-ish conditions, decent size, but the period is still short at 7 to 9 seconds, so don’t expect much push. It’s a marginal call, but it’s the only real option. Then Tuesday the 22nd gets a little weird – a 5 ft to 6 ft swell from the ESE with a very long period of 18 to 19 seconds, and the energy skyrockets to 2118. That’s a proper groundswell, but for a reef like Tengan, that long period can make it break a bit straight and tricky. Still, with light cross-shore winds and glassy mornings, it’s the standout of the whole forecast. Just keep in mind the inconsistency of the break – it’s not every day Tengan fires, so when it does, you gotta be on it. But don’t get too excited – the forecast for these later days is less certain, so keep an eye on the updates.

That’s the long and short of it. Anything in the second week is promising but a gamble. No other spots to jump to here, so it’s all about Tengan or waiting for the next change.

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.
