Alright mates, Rusty here, giving you the lowdown in feet and miles.
Honestly, for the next couple of weeks, the surf at Tengan is lookin’ like a bit of a tough stretch. We got a long gap of nothing, then some action that’s best left to the experienced crew.
Right now, things are flat and pretty grim. There’s a solid 8-day stretch from Saturday, July 6th, right through to Sunday, July 14th, where it’s just not worth paddling out. We do have a small window on Monday, July 7th and Tuesday, July 8th that’s interesting for the right person.
The standout, and I mean the only real window for a beginner, is Tuesday, July 8th. The morning is looking magic with glassy conditions and clean 3ft swell from the ESE, with a 13-second period giving it some decent grunt. The combined energy is moderate at (318), and Tengan is fairly exposed to that direction. It’s an inconsistent reef break, so you’ll be waiting for sets, but when they come, you’ll have clean little waves. The afternoon is even better with 3ft swell from the ESE, a very long 16-second period, and still glassy (combined energy 519). Water temp is about average for the time of year.
After Tuesday, July 8th, things get messy. Wednesday, July 9th, through Thursday, July 10th, the swell jumps up over 8ft from the SE and ESE with 18-second periods—that’s expert territory only, and the wind is howling cross-on, making it choppy and lumpy. Combined energy is strong to very strong (2973 to 7231). It’s a poor surf setup, honestly looking more like it’d be fun for kite surfing than paddle surfing.
Then from Friday, July 11th, to Sunday, July 14th, it’s a washout with storms and strong winds, and the swell all but disappears. There’s a tiny 0.7ft pulse from the E on Sunday afternoon with a 10-second period (combined energy 8), but with cross-shore winds, it’s barely a ripple.
We get a few tiny pulses of 3ft and 4ft swell towards the end of the forecast (around July 20th and 21st), but the onshore winds ruin any chance of quality. Overall, unless you’re an expert looking for big, messy power on July 9th, give it a miss until the forecasts change.
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.
