The Lowdown

Right, grab a coffee, and let’s talk about Tengan. I’ll be straight with you – this is a tough outlook. It’s looking like a real dry spell for the next 16 days. The first record starts on Saturday, 5th September, but honestly, the whole period is a struggle.

We kick off Saturday morning with a 6ft swell from the NNW, but it’s a messy one. The wind is a cross-offshore at 19 mph, and there’s a risk of thunderstorms. The combined energy is moderate (681), but the conditions are described as marginal. The water temperature is 84°, which is about average for this time of year. That first morning is the most interesting wave height we see, but it’s not clean. By Saturday afternoon, the swell drops to 4ft and the wind, while still cross-off, is a moderate breeze, but the surf is poor.

The rest of the first week is a washout. Sunday, the 6th, has a 6ft swell from the NE, but it’s a short-period 6s windswell, and the wind is a fresh cross-onshore at 19 mph. Lumpy, choppy, and no good. Monday and Tuesday are more of the same: 5ft to 6ft of swell, but the wind is cross or cross-off, and the period stays short. The wave energy fluctuates between moderate and strong (516 on Tuesday morning), but the wind keeps it ugly. The rest of the week just fades.

From Wednesday, 9th September, the swell drops under 5ft and never really recovers. The wind stays cross-on or cross-off, but it’s light to moderate, which is kinder. The problem is, the swell is small – 1ft to 2ft for most of the second week. For a break like Tengan, which is a reef setup and inconsistent, those tiny waves are just not going to work. The periods do get long (14s on the 13th and 12s on the 17th), but with barely any wave height, that long-period groundswell is just a ripple. The combined energy is weak (20-90) for most of those days.

Honestly, there isn’t a single standout session in this whole 16-day window. The conditions are poor, the swell is small or wind-affected, and the consistency isn’t there. The best you could hope for is a marginal, clean-ish morning on the 5th with that 6ft, but the trade-off is the wind and the storm risk. Other than that, it’s a long gap of flat or ugly surf. It’s a blank run for the area, and it’s pretty normal for Tengan to go quiet like this. Keep an eye on the forecasts, though – it tends not to stay this poor forever.

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.
