Alright, let me tell you how it’s shaping up for Tengan.
Honestly, the next couple of weeks are looking pretty bleak for us. There's a big gap of flat, windy, or stormy days ahead, so you'll have to be patient. Let’s walk through it.
We start off with nothing on Sunday the 5th of July – just some weak, short-period junk at 1.0ft from the ESE, with a cross-off breeze. Combined wave energy is a paltry 16, and the conditions are poor.
Monday the 6th isn't any better. The morning is flat and poor, with energy only at 57. The afternoon bumps up to a tiny 1ft and 102 energy, but the forecast still calls it ordinary.
Then we get the only real window of hope. Tuesday the 7th of July. This is the standout. By Tuesday morning it goes glassy, with a clean 3ft from the ESE at a long 13-second period. Combined energy jumps to a solid 318. By the afternoon, it’s even better: still glassy, with the swell building to 3ft from the ESE and the period stretching out to a nice 16 seconds. The energy climbs to 519. For a beginner-friendly reef break that’s normally inconsistent, getting this with glassy conditions is a rare treat. The water temperature is about 82°, which is pretty normal for this time of year.
Don’t get too excited for what follows, though. Wednesday the 8th turns messy. The swell jumps up to 7ft from the SE with a long 18-second period, but the wind swings cross-on from the NE, making it choppy. The energy is huge, over 2600, but the quality drops. By Thursday the 9th, it’s 10ft SE with strong onshore winds and storms – dangerous and poor.
From Friday the 10th right through until Monday the 20th of July, the surf is essentially flat or blown out. Strong winds, thunderstorms, and tiny, short-period leftover swell dominate the forecast. The combined energy drops to single digits and low teens for days at a time. There are a few glassy moments on the 14th, 17th, and 18th, but the swell is just too small (0.7ft to 1ft) to do anything with. It’s a dry run.
So, if you want the only wave worth paddling for, make it Tuesday the 7th of July at Tengan. Get it while it’s glassy and clean, because after that, it’s a long wait.

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.
