The Lowdown
Alright, let’s get this straight right off the bat – the next week and a half at Tengan is looking pretty grim. We’re talking day after day of tiny, gutless surf. The swell just isn’t showing up. From Tuesday the 14th right through to the morning of Monday the 27th, it’s pretty much all 0.7ft to 1.0ft of weak, short-period windswell. The combined energy barely scrapes double digits, mostly sitting between 6 and 22 (weak energy). You’d be scratching for anything rideable. The water is sitting at 82°, which is a bit colder than normal for this time of year, so you might want a thicker spring suit if you’re committed.
Now, there is a little flicker of hope right at the tail end. Monday afternoon the 27th, we finally see a bump. The swell pushes up to 2ft from the ESE with a period of 13 seconds, and the combined energy jumps to 118 (moderate energy). It’s still described as “ordinary” conditions, but it’s the first real sign of life. The wind goes glassy, so it’ll be clean. This is a reef setup, Tengan, and it’s inconsistent, so don’t expect a lineup. But for a beginner-friendly spot, that’s your best window.
Then Tuesday the 28th is the real standout. The swell builds to 3ft from the SE, period 10 seconds, and the combined energy hits 242 (moderate energy). By Tuesday afternoon, we’re looking at 4ft from the SE with a 10-second period and energy of 337, with a clean cross-offshore wind. That’s the best on offer in the whole 16 days. It’s still small enough for beginners, but it’ll actually have some push. The wind is light and clean, so the reef should be working nicely.
Wednesday the 29th morning drops back to 3ft from the ESE, still surfable but ordinary. By Wednesday afternoon, the swell collapses back to 0.7ft, and the period jumps to 19 seconds, but with that tiny size and super long period, it’s not going to do much for you here.
So, to sum it up: a long, flat run from the 14th to the 27th July, then a brief, promising pulse on the 28th. That Tuesday afternoon is the one to circle. Conditions look clean, the swell is there, and for a break that’s usually inconsistent, this is a rare moment of decent surf. Don’t hold your breath for the rest of the window.

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.
