The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Tengan over the next couple of weeks.

Gotta be straight with you – the first week is a write-off. From Monday the 27th of July right through to Sunday the 2nd of August, it's just flat. Tiny waves, barely a ripple. The water temp is sitting at a warm 85°, which is about normal for this time of year, but there's no juice to go with it. You're better off finding something else to do.

Things start to stir on Monday the 3rd of August. A new swell bumps up to 3 ft from the east, with a long 15-second period. The energy is moderate (282), but the wind is howling cross-shore from the north-northeast at 12 mph, so it'll be a bumpy, choppy mess. Not worth paddling out.

Tuesday the 4th sees the swell push to 4 ft from the east, period stretching to 17 seconds. The energy is climbing into strong territory (809), but that cross-shore wind is still a problem. The afternoon session gets a slight downgrade from "poor" to "marginal" – still not great.

The real story unfolds from Wednesday the 5th. The swell builds steadily, hitting 6 ft from the east on Wednesday afternoon, with a massive 18-second period and very strong energy (1760). These are groundswell pulses, but the wind is cross-onshore, keeping the quality down. The waves are there, but it's not clean.

The standout window opens on Saturday the 8th of August. The morning brings a solid 8 ft swell from the east-northeast, with an 18-second period. The energy is enormous (4404). But the kicker is the wind – it finally swings offshore from the west-northwest at 9 mph. That's the recipe for clean, groomed lines at Tengan. This is a reef break, so that long-period groundswell will wrap in nicely. It's a powerful wave, over 8 ft, so this is strictly for experienced surfers. Crowds are a possibility here, so get there early.

Sunday the 9th of August is a monster. The swell jacks up to 16 ft from the northwest in the morning, with a shorter 10-second period. The energy is off the charts (7157). The wind is still offshore from the west. This is huge, raw power. It's exceptional, but only for experts. The afternoon swings to a 15 ft swell from the north, still with clean offshore winds. This is the big one.

Monday the 10th of August is another gem. The swell drops to a still-very-large 13 ft from the north, with a 14-second period. The morning is glassy – winds are light and variable from the east-southeast. For a few hours, Tengan will be absolutely perfect. The energy is still very strong (6043). This is the best of the best for experienced surfers. After the morning, the wind picks up onshore, so the window is short.

After that, the swell starts to fade fast through Tuesday the 11th, with the wind turning onshore and chopping it up. The window closes.

So, for the best on offer, I'm calling it: Saturday morning the 8th of August for the clean, powerful 8 ft groundswell, and Monday morning the 10th of August for that glassy, 13 ft beast. Both are expert-only, but the quality will be unforgettable.

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.
