The Lowdown
G’day, Rusty here. Not gonna lie, I’ve been staring at the charts for a while, and this is a tough one. For the next two weeks, Suicide Cliffs is all we’ve got to talk about, and the first week is basically a write-off. We’re looking at a long, dry spell with some serious weather ripping through.
It’s not until Wednesday the 2nd of September that anything interesting happens. For days before that, the wind is howling straight onshore or cross-onshore, the swell is blown to bits, and the whole setup is a mess. There’s a moment on Tuesday the 1st of September morning when the wind goes offshore but it’s a near gale at 28 mph, so you’re not surfing; you’re just getting sandblasted.
Now, the standouts are all in the second week. The real event kicks off on Wednesday the 2nd of September afternoon. We get a massive pulse of swell from the southeast at 30ft, with a long 12-second period. The combined swell energy is absolutely nuts at 24325 – that’s serious power. But here’s the kicker: the forecast says it’s predicted to be too big for the break. For a reef like Suicide Cliffs, anything over 8ft is already expert territory, and 30ft is just terrifying. Only the most seasoned chargers with a death wish would even look at it. The wind is a near gale cross-off, so it’d be clean, but you’d be paddling into a freight train.
After that, things clean up nicely. Saturday the 5th of September is where I’d park the tray. Saturday morning you’ve got a clean 8ft swell from the southwest, period at 9 seconds. The real beauty is the wind: light, offshore from the north-northeast at only 3 mph – glassy conditions. The combined swell energy is a solid 1169, so there’s plenty of push. This is excellent surf for experienced surfers. The afternoon is just as good, with a 5ft southwest swell and a longer 11-second period, still clean and cross-off. Sunday the 6th of September morning is another cracker: 6ft of southwest swell with a very long 14-second period. That long period tells you it’s a proper groundswell, and for a reef like Suicide Cliffs, that means deep, powerful lines. Also light winds at 6 mph. The energy is 1514.
Just keep in mind, this place can get crowded – it’s listed as “often” busy. For a standout spot like this, on a day with those conditions, expect a pack out there.
Alright, hold tight, we’ll have to sit through a lot of junk before the good stuff shows up. Stay keen.
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.
