The Lowdown

Alright folks, Rusty here with the outlook in feet and miles.

Let’s be real – this is a tough stretch of water. The first decent chance doesn’t roll in until the morning of Wednesday, September 16th, and even then it’s a long shot. Before that, it’s a whole lot of close-outs and flat spells.

We’re looking at Tengan as the only real option. It’s a reef break that’s inconsistent and likes a northeast swell. The water temp is about par for the course.

So, starting Sunday the 6th and Monday the 7th, we see some chest to head-high swell (6ft to 6ft) but it’s coming from the north-northeast with a weak, short period. The wind is blowing a fresh 30 km/h cross-onshore and cross-shore, making it lumpy and choppy. A total washout.

Tuesday the 8th has a bump in energy (717) with a 5ft north-northwest swell, but that cross-shore wind is still creating a nasty cross-chop. The same messy, poor conditions stick around through Wednesday and Thursday the 9th and 10th, with the swell dropping.

Then we hit a dead zone. From Friday the 11th to Tuesday the 15th, the swell is knee-high or smaller, the wind is onshore, and the energy is weak. A full week of nothing.

The first real spark is on Wednesday morning, the 16th of September. The wind finally shifts to a clean cross-offshore from the south-southwest at 30 km/h. The swell is small (2ft) but has a decent 10-second period from the east. The energy is still low (153). By the afternoon, the swell pushes to 3ft and the energy picks up to 301. It’s only a marginal call, but the clean conditions are a huge win. This is your best window, but it’s a longboard session.

After that, it’s back to flat. The 17th, 18th, and 19th have tiny, weak swell. The last week of the forecast is dead, with wave heights under 1ft. A long, quiet run.

So, the only real standout is the morning of Wednesday, September 16th at Tengan. The clean wind makes it the most rideable option, even if the swell is small. Don’t expect much else.

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.
