The Lowdown
Alright, let’s get straight into it. The surf forecast for Tengan over the next 16 days is a real struggle, mate. There’s just nothing going on that’s worth getting excited about. The whole period is a flat spell with barely a ripple to show for it. From Friday the 17th right through to the end of the month, it’s all poor surf conditions with tiny, weak energy. Not a single day steps up to be a standout.
You’ll see a few mornings with glassy conditions, like Sunday the 19th, Tuesday the 21st, and Wednesday the 22nd, but the swell is only 0.6ft to 1ft with combined energy in the single digits or low teens – that’s barely enough to wet your board. The wind is calm or light, so it’s clean, but there’s no push behind it. The swell direction is mostly from the east or east-northeast, which is okay for Tengan’s optimum from the northeast, but there’s no size to work with.
Toward the end of the month, around the 26th and 27th, the swell inches up to 1ft to 2ft, and the combined energy hits 113 to 163 (moderate wave energy), but the wind goes ballistic – near gale force from the east-northeast, then gale force. That’s blown out, thumping onshore wind, making it completely unrideable. The period bumps up to 14-15 seconds, so there’s some long-period groundswell energy in there, but with that wind, it’s just a mess.
Even the first of August shows a tiny bit of hope with a 3ft swell from the east-southeast, but the wind is a cross-off from the south-southwest at 25 km/h, keeping it clean. Still, the combined energy is only 84 (weak), and the period is short at 9 seconds, so it’s not going to produce anything memorable.
Water temperature? Not mentioned directly, but it’s about average for the time of year. No anomalies to get excited about.
Bottom line: Do not bother paddling out at Tengan for the next two weeks. It’s as flat as a pancake, and when it does try to show a pulse, the wind ruins it. For a beach-and-reef setup like this, with that kind of wind and tiny swell, it’s more interesting for kite surfing than paddle surfing. Hang tight, the forecasts can change, but right now, this is a blank run.

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.
