Updates in hr min s Forecast update imminent
Right, let's have a look here. We only got one spot on the map: Tengan. A beginner reef break, but honestly, the next couple of weeks are a tough watch.
First up, Monday the 6th of July, just forget it. We’re looking at ankle-snappers, maybe 1ft from the ESE. Winds are cross-offshore, but the energy is pathetic, reading just 71 in the morning. Not worth wetting your wetsuit.
Then, Tuesday the 7th of July, that’s your day. That’s the one. The morning goes glassy with a light SSW breeze at 3 mph. Swell bumps up to a clean 3ft from the ESE. The combined energy hits 318, a solid moderate push, and by the afternoon it’s even better at 436 with 3ft waves and still glassy. That 16-second period is pure groundswell, so expect long, beautiful lines wrapping into the reef. Water temp is 82°, dead average for the time of year. But remember, Tengan is an inconsistent break, so when it’s on, it’s on. This is your window.
After that, it’s all downhill. Wednesday the 8th of July brings swell up to 7ft, but the wind swings onshore from the NNE at 12 mph, making it a choppy, blown-out mess. The energy is huge at 2539, but it doesn’t matter if it looks like a washing machine. Thursday the 9th of July is worse, with 10ft to 11ft surf from the SE and onshore winds screaming at 22 mph with thunderstorms. That’s big-wave territory for experts only, and the quality is junk.
Friday the 10th of July is flat. Nothing. From Saturday the 11th all the way through to Tuesday the 21st of July, it’s a long, sad run of "poor surf conditions." Every day is either choppy, blown out, or just too weak to do anything with. You’ll see a 5ft day on the 11th, a 7ft day on the 13th, but every single one has onshore or cross-onshore wind ruining it.
So the takeaway from this whole 16-day forecast is simple: if you want a surf, your one and only shot is Tuesday the 7th of July. Don’t miss it.

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.
