The Lowdown
G’day, Rusty here. Let’s be straight with you – this 16-day stretch for Suicide Cliffs is a tough one. We’re looking at a long, flat spell for the most part, with a massive pulse of energy right at the very end that’s ruined by nasty wind. The start is a total washout, and honestly, there’s not one session I’d get excited about for a paddle.
The first real flicker of swell doesn’t show until Friday the 18th of September, with a tiny 1 ft S swell pushing in, but it’s short-period (8 seconds) and the combined wave energy is a weak 22. Cross-off winds from the ENE will keep things clean, but with that size, you’re barely getting a knee-high ripple. Saturday morning the 19th sees a slight bump to 2 ft from the south with light offshore N winds (10 km/h), offering the cleanest little wave of this whole dry period, but it’s still weak soup (34 energy). After that, it’s back to tiny bits of S swell or flatness.
From the 22nd right through to the morning of the 28th of September, it’s almost totally flat. There’s a glassy day on the 23rd with a 1 ft SE swell, but that’s it. This is a proper dead run.
Now, Monday the 28th of September is where things get interesting, but not for us. A massive WNW groundswell hits, 16 ft in the morning (13 ft in the arvo) with a period of 10 seconds and a combined energy reading of 4821 – that’s a serious, powerful, solid ocean. The problem? It’s accompanied by a strong onshore E wind at 22 mph, making it a cross-shore mess. For a reef break, this is just dangerous and blown out. Tuesday the 29th still has size (6 ft to 6 ft) but with the same cross/cross-on wind, the quality is shot. This setup would be more interesting for kite surfing than paddle surfing.
In short, nothing worth paddling out for. The water temp sits around 84° on the 16th, which is about normal for the time of year, but you won’t feel it on a flat board. That last swell is a monster, but it’s completely unsurfable for us. Hang tight.
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.
