The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for Tengan over the next couple of weeks. Honestly, this is a tough one to write because the surf window is basically closed for days on end. We’ve got a solid 16-day run ahead but the first real chance of anything rideable doesn’t show up until Saturday, August 16th. That’s a long, quiet stretch to sit through.
Let’s break it down. The first few days are a write-off. We get some swell pushing through Monday the 3rd with an ESE swell at 3 ft, but the period is a touch short and the wind is messy. The wave energy is weak (303) and conditions are chopped out. The water temp is about average for this time of year, nothing unusual. Tuesday and Wednesday see the swell build, but the wind swings onshore and stays there, ruining any chance of a clean wave. By Thursday the 6th, the swell is over 12 ft and the wind is strong, making it a complete mess for a paddle. Then Friday the 7th through to Monday the 11th brings a monster pulse – we’re talking 25 ft to 34 ft of north swell with serious gale-force winds. That’s too big for anyone but the most experienced chargers, and even then, the wind and tide don’t line up for this break. The combined energy is astronomical (50308), but it’s not for surfing. We then go into a dead spell from the 12th through the 15th where there’s nothing on offer at all.
The only light at the end of the tunnel is Sunday, August 16th, early. That morning we get a 5 ft NNW swell with a short period of 8 seconds, and the wind is light out of the NNW – that’s offshore and clean. The wave energy is moderate (218). It’s not going to be epic, but it’s surfable. The break is a reef, and the swell direction is from the NNW which is cross-off, so it should hold shape. The trouble is Tengan is inconsistent, so you need the stars to align, and this is a short-period swell, so expect a bit of a chop on the face. Still, it’s the only real opportunity in the whole run. After that, it drops back to flat or tiny.
So, the one standout here is Tengan on Sunday morning, August 16th. If you can wait that long, you’ll get clean 5 ft waves from the NNW with light offshore winds. It’s not a classic, but it’s the best we’ve got. For the rest of the month, you’re better off checking the forecast again.
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.
