G’day, Rusty here, checking the Tengan zone for the next couple of weeks. It’s a slow start, but there’s a little window of magic mid-week if you’re patient.
Right now and through the first few days, it’s flat and forgettable. Tiny 0.3ft to 0.4ft ESE swell with weak energy (15 to 102), cross-off winds, and the wave comment is “poor surf conditions” – not worth paddling out for. The water’s at 81°, which is a bit colder than normal for this time of year, but nothing extreme.
The real standout is Tuesday, 7 July. Tuesday morning sees that ESE swell bump up to 3ft with a 13-second period, and the wind swings to a glassy north-northeast at just 3 mph. The combined energy hits 328 (moderate), and the wave comment says “expect good surf conditions.” Then Tuesday afternoon is the pick of the entire period. The swell holds at 4ft from the ESE, but the period lengthens to a very long 18 seconds – proper groundswell. The wind goes dead calm, 0 mph from the north-northeast, and the conditions are glassy. The wave comment reads “expect very good surf conditions,” and the energy is a solid 768 (moderate). This is the session to chase. The reef at Tengan should handle that long-period swell well, and with clean, glassy conditions, it’ll be a ripper. Just keep in mind that long-period swells can be a bit straight at beach breaks, but for a reef setup like this, it’s ideal.
From Wednesday, 8 July, things get messy. The swell jumps to 8ft to 8ft from the SE with an 18-second period, but the wind turns cross-on from the north-northeast at 9 to 12 mph, and the energy climbs into the thousands (3442 to 3579). The wave comments go to “marginal” and then “poor” – it’s lumpy and choppy. By Thursday and Friday, that swell peaks at 18ft on Friday morning with onshore wind from the east at 28 mph and energy over 18,000 – that’s dangerous, not surfable. It’s a write-off after Wednesday.
The rest of the second week from 13 July onward is a gap of flat, weak windswell with tiny 0.7ft to 2ft pulses and poor conditions. There’s nothing to recommend after Tuesday, 7 July. The setup is more interesting for kitesurfing than paddle surfing during the big, windy days.
So, in short: the only real standout is Tuesday, 7 July, especially the afternoon. That’s your window. The rest is a long, quiet stretch.
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.
