The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Suicide Cliffs over the next couple of weeks.
First up, the water temp is sitting right around 84°F—pretty standard for this time of year, so no surprises there.
The outlook is a tough one. We've got a 16-day window, but the truth is, the first week and a half is pretty much a write-off. There's a stretch from August 30th all the way through to the morning of September 10th where the conditions are just no good for a paddle. The surf quality is consistently poor, with either strong cross-onshore winds, lumpy chop, or just messy conditions. You're looking at mostly poor surf flags across the board, and the energy levels are weak too, mostly hanging around 200-300 (for the combined energy of all swells directed here) for the first week. It’s a long, flat, blown-out run with nothing worth getting wet for.
Now, the first real glimmer of hope shows up on Thursday, September 10th, in the morning. That’s where we finally get a bit of a pulse. A moderate offshore breeze from the north will be cleaning things up nicely. The swell is from the west at about 7ft, with a solid 11-second period – that's proper groundswell energy. The combined energy reading hits 972, which is a good sign. This is the standout option. It's got decent size, good shape potential from that long-period W swell, and clean conditions thanks to the offshore wind. It’s a reef break that's very consistent, so you know it’ll be breaking. Just keep in mind that 7ft is getting into the intermediate-plus zone, so it might be a bit much for beginners. Also, crowds are "often" there, so expect some company. This Thursday morning window is the best on offer.
After that, the afternoon of the 10th sees the wind pick up and the swell drop, and then it gets wild. The 12th brings storm-force winds – that’s kite-surfing territory, not paddle surfing. And from the 13th onwards, we’re back to onshore gales and tiny, lumpy waves.
So, to sum it up: don’t bother for the first week and a half. Your one shot is the morning of September 10th at Suicide Cliffs. It’s a bit of a wait, but that window looks promising for those who can handle it.
Rusty.

Information about the Suicide Cliffs Surf forecast
The above surf forecast table for Suicide Cliffs provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Suicide Cliffs can be found by selecting the local surf guide option on the grey menu. Our Suicide Cliffs 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 (Suicide Cliffs) 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 Suicide Cliffs 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.
Suicide Cliffs is 7 km (4 miles) from the city of Itoman. If you plan a holiday in Okinawa, look for hotels and other accommodation in Itoman. Itoman has rooms for a wide range of budgets as well as car hire and transport links.
