The Lowdown

Alright, mates, let's get into it. Rusty here, and I've got the full 16-day picture for you. The short of it is, we're looking at a pretty grim stretch for a while. The first bit, into the middle of the month, is a write-off. Then, we get a sniff of something in the distance, but it's a long way off and not a sure thing.

The first real recommendation doesn't show up until Thursday, August 6th, but it's a total pass. Tengan's got a 10ft swell coming from the East, with a very long period of 16 seconds. That's a lot of water moving, but it's being hammered by a 25 mph north wind, making it a cross-shore mess. The water is a touch warmer than normal at 86°F.

That big swell is followed by a serious storm on Friday the 7th, with a 20ft swell from the North and 47 mph winds. It's just not safe. The whole weekend into the next week is a washout; we're talking days of gale-force winds, heavy rain, and tiny, chopped-out surf. From the 8th of August until the 19th, the swell is mostly under 3ft, and the wind is howling. It's a proper blank run for any kind of decent wave.

Now, we start to see some life on the 20th of August, Thursday. The swell picks up to 3ft from the East with a period of 9 seconds, and the combined energy is a moderate 136. The wind is light onshore, so it's not clean, but it's a start. The 21st of August, Friday, is very similar, with 3ft from the east-northeast and a 130 energy reading. The wind is still onshore, so you're dealing with chop.

The best of the whole 16-day window is a tough call, but I'd have to point to the 20th and 21st of August. The swell is small, but it's the most consistent energy we've seen all period. The combined energy of 136 and 130 is the highest we've had since the storm. The wind is light, which is about the best we can hope for. The break is Tengan, a reef. It's a beginner spot, and it's inconsistent, so it's not for everyone, but it's the only game in town. The swell direction is east, which is a solid match for the break's optimum.

For the rest of the period, from the 22nd onward, the data goes quiet, but the pattern suggests we're still waiting for a proper swell. The near-term is a total loss, and the long-range looks promising, but it's a long way out, so keep your fingers crossed.

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.
