Right, gather 'round… Rusty here. I’ve had a good look at the numbers for this spot, and honestly, it’s a pretty flat spell we’re staring down. Don’t expect to be surfing much for the next couple of weeks.
First thing, the only break on the cards is Tengan, a reef setup that’s inconsistent and really only for the beginners when it does get something. The water’s sitting at a warm 84°, which is pretty average for the time of year, so no surprises there.
The outlook starts on Monday, 13 July, and it’s a real struggle. We’ve got a tiny 0.3 ft easterly swell with a weak 9-second period, and a crosswind blowing at 16 mph. The combined energy is a measly 2, which is basically nothing. It’s "poor surf conditions" all the way through. Tuesday through Thursday of that first week stays tiny, with 0.7 ft to 1.0 ft, and the wind flips around but stays mostly cross or light offshore. The energy figures are in the single digits for most of that, so it’s all flat and clean but useless for paddling.
Friday, 17 July, and through the weekend, it’s the same story. Some 0.7 ft to 1.0 ft east-southeast swell, short period around 9 to 10 seconds, and energy figures barely cracking the teens. The wind goes light offshore or cross-off, so it’s clean, but there’s just no push. You’d be doing more floating than surfing.
We hit the second week, around Monday, 20 July, and the wind starts turning onshore, making it even less appealing. The swell stays tiny, 0.7 ft to 1 ft, with energy figures still in the low double digits. By Thursday, 23 July, it’s a similar deal with onshore winds. The best we see is a hint of a 1 ft east-northeast swell on the 24th with an 11-second period, but the energy is only 41, and it’s straight onshore, so it’s all messy.
The last few days of the outlook, from 25 July through to 28 July, show a slight lift in the swell to 2 ft and 2 ft with an 11-second period and energy figures hitting 60 and 90. It’s still labeled "poor surf conditions" though, with onshore or cross-onshore winds. The period is enough to suggest a bit of shape, but it’s breaking straight on that reef with the wind, so it’s not a pretty picture.
Honestly, there’s no standout session here. Not a single one. The entire 16-day window is a gap of flatness and poor conditions. For a spot like Tengan that’s already inconsistent, this blank run is pretty normal for the area. Sometimes the ocean just takes a holiday. Keep the board waxed, but don’t rush to the water.
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.
