The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, I’m looking at a pretty flat spell for Tengan, and it’s a bit of a bummer. The whole 16-day window is basically a bust for any kind of decent surf. We’ve got a solid week and a half of nothing happening, from Wednesday the 15th right through to the end of the month. The combined swell energy is absolutely tiny, barely hitting double digits (7 to 11) for the first week, and even when it picks up a bit, it’s still weak. The water is a bit colder than normal, sitting at 81°F on the 15th, which is a touch cooler than usual for this time of year.
The best of a bad bunch might be the glassy conditions on the 24th of July, a Friday morning and afternoon. The wind is dead calm, which would make the water look like a mirror, but the swell is only 0.7 ft from the ENE shifting to SE, so it’s more of a paddle-around than a surf. The waves are just too small and weak to do anything with.
For the rest of the period, it’s a mix of tiny 0.7 ft to 1 ft waves with onshore or cross-off winds. By the 28th, the swell does bump up to 4 ft, with combined energy hitting 217, but it’s coming with risk of thunderstorms and a fresh onshore breeze, making it lumpy and unappealing. It’s a classic case of ‘lots of energy, no clean shape’. The direction is from the ESE, but the optimum for Tengan is NE, so it’s not even lined up right.
Honestly, if you’re keen on getting wet, this setup might be better for a kite than a paddleboard, especially when the wind picks up late in the month. There’s just no stand-out session here. The breaks are inconsistent, and with so little swell, it’s a quiet time. Forecasts can change, but right now, I’d be hanging up the board for a bit.

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.
