The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Straight up, I’ll be honest with you – this is a rough stretch. From now through the entire 16-day window, we’ve got no real surf on offer here. The data shows a long, dry run of 'poor surf conditions' with scores that just don’t stack up for a proper paddle. We’re looking at a solid blank run, which isn't unheard of for this area when the winds and swell just don’t line up.

We start on Monday the 10th of August with a bit of a messy scene. A risk of thunderstorms, a cross-onshore breeze from the southeast at 16 mph, and a weak 3 ft easterly swell with a 14-second period. The energy is low at 239, and it’s choppy. Not your day. That trend continues through the week with tiny, weak swell, mostly under 2 ft, and cross-onshore winds. There’s a brief moment of clean conditions on Wednesday afternoon the 12th with a light cross-offshore breeze, but the swell is still only 1 ft from the ENE with a period of 11 seconds and energy down at 39. Hardly enough to get out of first gear.

The weekend of the 15th and 16th is more of the same. Small, weak ENE pulses, but on Sunday the 16th we get a glassy afternoon. Still, the swell is just 1 ft with a 10-second period and 33 energy. It’s calm, but there’s nothing to ride.

The second week gets a bit more interesting, but not in a good way for paddle surfing. From the 21st of August, a larger swell arrives – 5 ft from the southeast on Friday morning, with a period of 8 seconds and energy jumping to 267. But the wind is a cross-onshore 12 mph, making it choppy and lumpy. That swell builds, with the biggest pulse hitting on Tuesday the 25th of August: 6 ft from the east, 12-second period, and a strong energy reading of 952. That’s a proper groundswell, but it’s arriving with a fresh onshore wind from the ESE at 22 mph. The conditions are just blown out.

For a break like Tengan, which is a reef setup that does best with a NE swell direction, none of this is working. The swell is coming from the wrong directions, and the wind is constantly onshore or cross-onshore. If you’re into kite surfing, those bigger, windier days from the 21st onward might look a bit more appealing, but for a paddle surfer, there’s nothing to get excited about.

So, keep your gear waxed, don’t bother rushing down here. The forecasts change, and it won’t stay this flat forever, but for now, it’s a solid no-go.

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.
