The Lowdown
Alright, Rusty here. Let's have a look at the charts for Tengan.
Right off the bat, I gotta be straight with you: it's a grim spell. We're looking at a solid 7-day stretch of nothing worth paddling out for, from Saturday the 12th all the way through to Friday the 18th. It's one of those periods where the ocean just feels flat and messy, with weak swell and onshore breezes kicking up chop.
Things get a bit more interesting from Saturday the 19th. A healthy spike in energy hits, with combined swell energy climbing into the thousands, but the wind is a real letdown – strong cross-shore winds will make for a lumpy, blown-out mess. Sunday the 20th is worse again, with near gale-force cross-shore winds making it pretty much unsurfable. The swell's big, but the quality is junk.
Now, the real standout here is Tuesday the 22nd through Wednesday the 23rd. We get a proper window of clean surf. Offshore winds from the west will groom that 13ft of north-northwest groundswell coming in with a period of 13 seconds into something with real power and shape. However, that's a whole lot of water moving – well over 8ft – so this is strictly for the experienced crew who know how to handle a heavy reef. The combined energy is reading over 5000, which tells you there's serious grunt behind it. For the experts, Tuesday afternoon and Wednesday morning look the pick of the whole 16 days, with cleaner conditions and still plenty of size.
For the rest of us, it's a waiting game. After that clean pulse fades, we're back to onshore winds and choppy conditions through the end of the month.
Tengan is an inconsistent reef break, and a spot like that really needs the stars to align. This time around, they only do for a couple of days, and it's for the big-wave chargers.

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.
