The Lowdown
Alright folks, this is Rusty. Let's get into it.
Right off the bat, things are looking pretty grim at Suicide Cliffs for the first week. We’ve got a solid stretch of nothing but crossed-up wind and messy conditions. The water temp is sitting at a balmy 84°, which is bang on average for the time of year, so at least you won't be needing a thick wetsuit. But from Monday the 31st of August all the way through to the end of the first week, it’s a write-off. The wind is hammering out of the east at 19 mph, creating a lumpy cross-chop that'll have you fighting for every inch. The swell is there, but it’s junk. The combined energy is moderate at best (222), but it doesn't matter when the surface is that blown out.
Things start to show a glimmer of hope on Monday the 7th of September. That morning, the wind swings around to the north, blowing offshore at 9 mph. That’s a game-changer. The surf is small, only 4 ft from the south, but it’ll be clean as a whistle. The energy is weak (206), but the glassy conditions will make it a fun and easy session. Not a standout, but a nice reprieve.
Now, listen up, because this is where it gets interesting. The real gold is sitting way out at the back end of the forecast. The period from Friday the 11th of September through to Sunday the 13th of September is the one you want to circle on your calendar. We’ve got a massive pulse of SSW groundswell moving in, with a very long period of 12 to 14 seconds. This is serious energy. On Saturday the 12th of September, we’re looking at a solid 12 ft of swell from the SSW with a period of 14 seconds. The combined energy is a massive 4689, and the wind is blowing offshore from the north-northeast at 12 mph. This is going to be a day for experienced surfers only. That’s expert territory, and it’s going to be a freight train. The 12 ft swell is over 8 ft, so it’s strictly for the crew who know what they’re doing. The 14-second period will see the waves heaving up at Suicide Cliffs, a reef break, which is perfect for that kind of long-period groundswell. It’ll be a bit of a paddle, but the clean offshore breeze will keep the faces perfect. Crowds are likely here, as it’s a very consistent spot, but on a day like that, the lineup will be thinned out by the size.
The Sunday the 13th of September morning is almost as good, with another 12 ft from the SSW and a 13-second period, with clean conditions. The energy is still massive at 4637. After that, things slowly start to back off, but the wind stays clean for a few more days.
So, to wrap it up: the first week is a total bust. Forget it. The second week, Monday the 7th is a small, clean wave. The absolute standout, the one you need to plan for, is Saturday the 12th of September. That’s the big one. It’s a long-range call, so keep an eye on it, but right now, that’s the session to chase.
Stay safe out there.
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.
