The Lowdown

Alright, this is Rusty. Let's take a look at what Tengan has in store over the next couple of weeks.

Honestly, mate, it’s a pretty grim run for Tengan for a good stretch here. This is a reef break that’s inconsistent at the best of times, and for the first week and a half, the conditions are just plain ugly. We’re lookin’ at a long, dry spell with basically no surf worth paddling out for until we hit the very end of the first week of September. The water temp is about average for this time of year, so no surprises there.

The first real glimmer of anything decent doesn’t pop up until Saturday the 5th of September. That morning, we get a clean, 3.3ft wave from the NNW with a moderate offshore wind out of the west. The combined swell energy is moderate (300). It’s not huge, but it’s the first time the wind is actually workin’ with the wave. The afternoon drops off a bit to a 2.3ft E’ly swell, but still clean.

Sunday the 6th of September is the standout. The morning session is your best bet with a clean 3.6ft wave from the north, a period of 10 seconds, and a light offshore wind from the NW. The combined energy is moderate (356). It’s a proper, clean little wave. The afternoon stays clean with a 3.3ft north swell, though it's a touch smaller. This is the one to circle on the calendar—it’s the best we’re gonna get in this whole outlook.

Before that, don’t even bother. The middle of the second week, around the 3rd and 4th of September, we get some proper sized swell—9.8ft to 13.1ft—but it's accompanied by severe gale-force winds and stormy conditions. That’s a hard pass. The setup there is more interesting for kite surfers than for a regular paddle surfer.

So, to sum it up: a whole lot of nothing, then one tidy little window on the 5th and especially the 6th of September. Get on it if you can.

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.
