The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up.

First up, we’re looking at Tengan. This is a reef break, and it’s inconsistent, so it doesn’t always fire. The water temperature is sitting at 81°, which is a bit colder than normal for this time of year – about 3° cooler than average, so you’ll want a thin suit if you’ve got one.

Now, to be straight with you, the start of the forecast is a real struggle. From Saturday the 18th of July right through to the end of the month, the surf is mostly tiny and really poor. We’re talking waves around 0.7ft to 1.0ft – basically flat – with weak energy readings in the single digits and teens (like 11 to 28). The winds are cross-off or cross-on for most of that period, and even though there’s a glassy morning on Thursday the 23rd, there’s just no swell to work with. It’s a long, dry gap of about 9 days with nothing worth paddling out for.

The first real change comes on Monday the 27th of July. We get a jump in energy, with a 2ft swell from the ESE, but it’s onshore and lumpy from a fresh breeze. The next day, Tuesday the 28th, shows a bit more size at 5ft from the ESE, but the wind is howling at 28-34 mph, creating messy cross-chop. That’s kite-surfing territory, not paddle surfing.

Wednesday the 29th of July is the standout – but it’s a wild one. The swell hits 6ft from the E, with a period of 16 seconds, and the combined energy is massive at 1723 (strong). That’s a proper groundswell. The problem is the wind – it’s a severe gale offshore at 50 mph. That’s clean, sure, but it’s ridiculous to paddle into. This is strictly for experts only, and even then, it’s a battle. The swell direction is from the E, which is off the optimum NE for Tengan, and with that long period, it might break a bit straight, but it’s still the biggest wave of the window.

By the 30th of July, the swell drops to 3ft, and the wind backs off to a strong breeze, staying clean. Then on the 31st of July, we finally get a surfable but ordinary session: 3ft from the N, moderate offshore wind, clean conditions. The energy is moderate at 161, and the period is short at 8 seconds, so don’t expect much push. This is the closest we get to a decent paddle.

After that, it fades away again into the first days of August, with tiny waves and no real energy.

So, the honest truth is, there’s no classic day on offer. The only real standout is Wednesday the 29th of July if you’re an expert looking for a big, windy challenge. Otherwise, it’s a long wait for very little.

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.
