The Lowdown

Alright folks, Rusty here. Let's get into it. Honestly, it is a bit of a slow start at Tengan. We’re looking at a long stretch of tiny, weak swell that just won't get out of first gear. We’re talking about a full week of barely anything to ride. It's a tough run for a reef break that’s already on the inconsistent side.

Monday the 20th and Tuesday the 21st, you’re looking at tiny 0.7ft to 1.0ft waves from the east-northeast, with cross-off winds. The combined energy is barely there (7-16). It’s clean but there’s just nothing to push you around.

Wednesday the 22nd through to Friday the 24th, the swell stays microscopic, around 1.0ft. We do get a couple of nice glassy moments, especially early Wednesday and all of Thursday, with that combined energy creeping up a bit (15-23). But with that little juice, it’s a tough ask to get a ride. Friday turns a bit bumpy with a cross-on wind.

Saturday the 25th, still tiny, and the wind goes onshore.

Now, things finally start to stir on Sunday the 26th. The swell bumps up to 3ft from the southeast, with a 13-second period, and the energy jumps to a moderate 205. The wind is onshore though, so it won't be pretty.

Monday the 27th gets a bit messy. That southeast groundswell builds to 7ft with a long 14-second period, kicking up a strong combined energy (1733). Problem is, it's blowing a fresh 30 km/h cross-onshore, so expect lumpy, blown-out conditions. This one’s for experts only given the size, and the wind kills it.

Tuesday the 28th is a serious weather day. A massive 15ft swell from the southeast arrives with a storm-force 90 km/h cross-onshore wind. That's a total mess (12200 energy). Avoid the water.

But here’s where it gets interesting. Tuesday afternoon, as things begin to change, the wind swings to the northwest and drops to a cross-off 30 km/h. We get a 23ft wave from the northeast. That's a massive, powerful (17624 energy) pulse. The report says "marginal," but with that shift, the reef could get a window of clean, giant surf for the brave. This is the real deal, but you need to be a top-tier surfer.

The island then gets hammered by gale-force offshore winds from the west-southwest on Wednesday the 29th. The models are showing zero swell energy, so that’s a complete washout.

Thursday the 30th and Friday the 31st settle down with strong, clean offshore winds. The swell is still huge, running 12ft to 16ft from the northwest and north-northwest. That's serious groundswell (4218-7807 energy) with a very long 13-second period. The wind is strong offshore (40 km/h), so it will hold the face, but it’s going to be a battle to paddle out and get into position. This is expert territory only.

Into the first week of August, things start to ease off but stay solid. Saturday the 1st has 10ft from the north, still with a strong cross-off wind. Sunday the 2nd drops a bit to 7ft from the north with a moderate breeze and a shorter period.

The standout of the entire forecast is Monday the 3rd of August. We’ve got an 12ft groundswell from the north with a 13-second period (3690 energy). The wind is a gentle 15 km/h cross-off from the southwest. The report calls it “excellent surf conditions for experienced surfers,” and I agree. That's a clean, powerful day for the reef at Tengan. It’s not for the faint-hearted, but for those who can handle it, that’s your day.

Then Tuesday the 4th of August shows a classic drop-off: a much smaller 3ft swell but with a very, very long 17-second period from the east. The wind is a gentle offshore. That’s a clean, lined-up day for a longboard if the reef can pick it up, but the energy dips to moderate levels (388).

So, the bottom line: you wait through a week of nothing, survive a stormy mess, then you get that window from Tuesday the 28th through to Monday the 3rd for big-wave crew. The clear best day is Monday the 3rd of August. Mark it.

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.
