Alright, Rusty here. Let's have a look at what's comin' our way for Tengan. Gotta be straight with you, it's a slow start and a tricky stretch, but there might be a couple of windows if you're patient.
Tengan
Alright mate, so for Tengan, the opening days are a bit of a flat spell. We're looking at Friday the 3rd through Monday the 6th, with tiny waves around 1 to 2 feet and a light cross-offshore breeze. The water temp is sittin' at 81°, which is a touch cooler than usual for this time of year – about a degree and a half off, but nothing too wild. The energy in the water is real weak, only ticking over at 25 (weak energy) on that first day, so honestly, it's a paddle and a tan, not a surf. Not much to get excited about.
Now, the first real glimmer of hope shows up on Tuesday the 7th. Tuesday morning we get a bit of glass – wind goes dead calm from the southeast at just 3 mph, and that swell starts to push in a bit. We're lookin' at a clean 3 feet from the ESE with a solid 13-second period. That's a proper groundswell and the combined energy jumps to 320 (moderate wave energy). It's still small, but glassy and clean – a good morning for a longboard or a fun shape. Tuesday afternoon, the swell pushes up to 4 feet from the ESE with an even longer 18-second period, energy hitting 777 (moderate wave energy), and the wind is a light cross-offshore from the SW. That's the standout of the whole outlook, right there. Clean, building swell, nice long lines – a real treat.
But then, don't get too attached. Wednesday the 8th gets a bit more size but the wind starts to mess with it. Morning shows 7 feet from the SE with that long 18-second period and a solid 2812 energy (strong wave energy), but the wind is onshore from the ENE. That onshore wind at a beach-reef setup like Tengan will chop it up. That afternoon we're lookin' at 8 feet from the SE, but the wind clocks around to a cross-onshore from the NE, making it lumpy. It's too big for beginners and the quality drops off fast. By Thursday the 9th, it gets messy – 10 to 12 feet from the SE, strong cross-onshore winds at 16-19 mph, and the energy is huge at over 5300 (strong to very strong wave energy), but it's just a blown-out, choppy mess. Honestly, that setup might be more fun for a kite surfer than a paddle surfer.
After that, from the 10th through to the 18th, it's pretty grim. We get a run of strong onshore winds, some thunderstorms, and the swell just disappears again. A few tiny bumps here and there with some glassy moments on the morning of the 16th (2 feet from the SSE) but the period is a short 4 seconds, so it's weak and won't hold up. The energy barely cracks 65 (weak energy). It's a long, flat, and windy patch.
So, bottom line: The best on offer is Tuesday the 7th – that morning glassy session and that afternoon clean 4-foot groundswell. That's your window. The rest is either flat, too small, or blown out. Keep your eye on that Tuesday.

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.
