Updates in hr min s Forecast update imminent
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks. There’s a clear run of flat or weak days first, so don’t bother paddling out just yet. The real action is a one-day window mid-week, then it gets frustrating again.
The first real chance to get wet doesn’t arrive until Tuesday, July 7th. Things will be quiet before that, with just tiny, weak leftovers and poor conditions through Sunday the 5th and Monday the 6th. On Tuesday morning at Tengan, we start to see some life. The swell is moving in from the ESE at 3 ft, with a period of 13 seconds. That’s groundswell energy building, and the combined energy reads 273 (moderate). Wind is light cross-off from the NNW at only 3 mph, so it’ll be clean. Conditions are “expect good surf conditions.” It’s a reef break that’s inconsistent and mainly for beginners, but the quality is on the up.
The standout moment is Tuesday afternoon, July 7th. That’s the pick of the whole forecast. Swell jumps to 4 ft from the ESE, period stretching to 17 seconds – that’s a proper groundswell with real energy. The combined energy hits 717 (moderate to strong). And the wind? Glassy. Dead calm from the NW at 3 mph, described as “glass.” The note says “expect very good surf conditions.” This is your session. The swell direction from the ESE matches the optimum direction for Tengan (NE) reasonably well. Being a reef, that long-period swell will wrap in nicely. Water temperature is about average for the time of year.
Wednesday, July 8th is a step up in size but a steep drop in quality. The morning brings 7 ft from the SE at 18 seconds (very long period), with combined energy at 2842 (strong). But the wind turns cross-on from the NNE at 9 mph, making it choppy and marginal. That’s expert-only territory at 7 ft and messy. By the afternoon, it’s 8 ft and even more onshore. Not recommended for paddle surfing – if anything, this setup is more interesting for kite surfing with that strong cross-onshore wind. Then Thursday the 9th sees the swell spike to 10 ft and 12 ft with fresh onshore winds over 18 mph, and the energy reading is 5673 and 6962 (very strong). Poor conditions and dangerous. This is expert-only at best but looks unmanageable.
After that, from Friday, July 10th through to Sunday, July 19th, there’s a long, frustrating gap with next to no surf or just tiny, weak waves with onshore or cross-onshore winds. The energy values are low, often zero or single digits. There’s a small blip on Friday, July 17th with 3 ft to 6 ft from the east, but the wind is onshore to moderate breeze, and the quality is still rated poor. Nothing worth paddling out for. The spell of poor conditions stretches over a week with no solid recommendation.
So, in short: wait for Tuesday afternoon, July 7th at Tengan. That’s the only true gem in the whole 16 days. Glassy, clean, solid groundswell. Everything else is either too small, too windy, or too big and messy.
Stay patient,
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.
