The Lowdown
Alright folks, Rusty here. Let’s talk about Tengan. It’s a reef setup that’s a beginner-friendly spot, but it’s inconsistent – it doesn’t just fire up out of the blue. The water temp is sitting at 85°, which is about bang on average for this time of year, so no surprises there.
The next couple of weeks are looking pretty bleak for Tengan, to be honest. We’re looking at a long stretch of tiny, weak surf. From Monday the 27th of July all the way through to Sunday the 2nd of August, the swell is just a piddly 0.7 ft to 1 ft. The energy is laughable, rarely cracking double digits (9-27). Monday afternoon the 27th has a light cross-onshore breeze, making it a bit choppy, but it’s so small it doesn’t matter. Wednesday the 29th offers a brief moment of glassy conditions in the afternoon with a light WNW breeze, but again, the swell is only 1.0 ft with a short period.
You’re looking at nearly a full week of nothing worth paddling out for. It’s a blank run.
Things start to get a bit more interesting from Monday the 3rd of August. The swell bumps up to 2 ft from the east with a period of 15 seconds, and the combined energy jumps to 155 (moderate). The conditions are still a bit mixed with a cross wind, but it’s a sign of life. Tuesday the 4th of August sees the swell push to 3 ft to 4 ft from the east, with a long 17-second period. The energy is building into the moderate range (593-699), but it’s a cross-shore wind, so it’s a bit bumpy.
Now, the highlight of this whole outlook is the afternoon of Wednesday the 5th of August. We’ve got a 5 ft east swell at a 17-second period, which is a proper groundswell. The energy is strong (1329). The real kicker is the wind: it’s glassy with a light NNE breeze. That’s a major positive. For a reef break like Tengan, this long period, east swell is going to wrap in nicely, offering some clean, long lines. It’s the standout session. It’s a bit on the bigger side, so it’s not for beginners, but for the rest of you, that’s the one to circle on the calendar.
Thursday the 6th of August keeps the goods going with a 5 ft east swell (17s) and clean offshore wind from the west in the morning. The energy is still strong (1100+). The afternoon picks up a moderate cross-offshore breeze, but it stays clean. The surf hangs around through Friday the 7th and Saturday the 8th, dropping slowly from 5 ft to 3 ft, with clean conditions and glassy moments on Saturday morning. By Sunday the 9th, it’s all fading back to tiny, weak 2 ft waves with poor onshore winds.
So, to sum it up: the first week is a complete write-off for Tengan. The second week delivers a solid, clean groundswell window from the 5th to the 8th of August. The absolute best bet is the glassy Wednesday afternoon. Don’t sleep on that Thursday morning either. After that, it’s back to the waiting game.
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.
