The Lowdown

Alright, Rusty here, and I'm gonna give you the straight-up on the next couple of weeks. It's a bit of a waiting game, so don't get your hopes up too early.

The water temp is 84°F, which is pretty average for this time of year, so at least the water will be nice while you're waiting for the surf to show up.

The first four days, from Thursday the 27th of August through Sunday the 30th, are a total bust. The swell is tiny, barely breaking 1 ft, with weak energy (30-165), and the wind is a mess of onshore and cross-shore stuff. Choppy and lumpy is the name of the game.

Monday the 31st of August and Tuesday the 1st of September see a jump in size. Monday has about 5 ft to 5 ft of ESE swell, but with a risk of thunderstorms and a 35 km/h breeze. The energy is moderate (529-726). Tuesday the 1st gets bigger, around 8 ft, but the wind is howling from the NNW at 40 km/h, then 55 km/h from the NW. The energy is strong (923-1048), but it's all blown out. Better for kite surfers than for a clean session.

Then Wednesday the 2nd and Thursday the 3rd of September, the wind finally goes offshore, but it's strong. Westerly winds at 35-40 km/h will keep things clean, but the swell is inconsistent. Wednesday has 5 ft to 6 ft from the ESE, and Thursday morning has 5 ft from the E. It's a "marginal" call, but for the dedicated crew, it's worth a look.

Now, the one to get excited about. Saturday the 5th of September. This is the highlight. Tengan is a reef, so it needs a clean swell, and this is it. The morning has a 8 ft groundswell from the N, with a 12-second period. The energy is huge, 1578, and the wind is glassy, dead calm. The afternoon is similar, with a 8 ft swell from the NNW, 12-second period, and a glassy 5 km/h breeze. The energy is even stronger at 1622. This is for experts only, that size is serious, but the conditions are going to be excellent. The swell direction from the N is a good match for the NE optimum, and that long period gives it some real punch. This is the one.

After that, it's a bit of a letdown. Sunday the 6th of September through the end of the period, the wind swings back onshore, and the swells get messy. There are some huge swells in there, like 12 ft on the 8th and 18 ft on the 9th, but they are all accompanied by strong cross-onshore winds, making the conditions poor. The energy numbers are massive (3230, 6277), but it's just not going to be clean.

So, to put it simply: the first half is a dud, the middle has a couple of days for the hardcore, and the one clear winner is Saturday the 5th of September at Tengan. Be there if you've got the skills.

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.
