The Lowdown

Alright, this is Rusty. Let's get into it for the Tengan area.

Honestly, the first few days are a total loss. Tuesday the 4th and Wednesday the 5th are blown out with onshore wind and stormy weather. There's a solid gap of nothing surfable to start.

The first real event is Thursday the 6th in the morning. The wind switches to a clean cross-offshore, but the swell is a solid 12ft out of the east. That's a deep, powerful groundswell with a 18-second period, and the energy reading is 7526 – that's huge. For a reef break like Tengan, this is way too big for anyone but experts. The afternoon gets even windier, so the window is short.

Friday the 7th is the big one, and it's a monster. We're talking a 31ft to 39ft swell from the north. The energy numbers are insane – 37,301 in the morning, hitting 61,149 by the afternoon. The wind is clean, but it's violent storm force to hurricane-force. The forecast literally says it's too big for this break. This is a once-in-a-decade size event. Total spectacle, but for a reef, it's deadly. Only the most hardcore chargers.

After that, it drops off a cliff. Saturday the 8th has a 10ft leftover from the NNW, but the wind turns messy. Then from Sunday the 9th all the way through the 16th, it's a long stretch of tiny, weak, or flat conditions. A few bumps of knee-high swell with offshore winds on the 17th and 18th might give you a clean, small wave on a longboard, but the energy is low and the period is short.

The standout is the Friday the 7th swell, but it's a danger warning, not a call to paddle out. For everyone else, there's a long dry spell. Keep an eye on the forecasts.

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.
