The Lowdown
Alright folks, Rusty here. Let's get straight into what's on the table for Suicide Cliffs.
The first thing you need to know is that this isn't a typical surf window. We've got a massive pulse of energy coming through, but it's way too big for anyone who isn't a seasoned expert. The water here is sitting at a warm 86°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home.
The real action, if you can call it that, is this weekend. Friday the 7th is a total write-off: 20ft of WNW swell with a severe gale blowing cross-shore. That's not surf, that's a survival mission. The swell energy is massive at 7278, but the conditions are pure chaos.
Now, Saturday the 8th is where it gets crazy. The swell is coming from the SSW, right on the optimum direction for this spot. We're looking at a 26ft to 30ft swell with a period of 12 to 13 seconds, and the wind is howling onshore at 80 to 85 km/h from the south. The combined energy is off the charts at 18473 and 25072. The file says the wind and tide are favorable, but let's be real: at 26ft to 30ft, this is only for the absolute elite. Beginners and intermediates should not even think about it.
Sunday the 9th drops to 16ft with a near gale, but it's still showing poor surf conditions. The energy is still massive at 12407 and 10436, but the wind is making a mess of it. The same goes for Monday and Tuesday the 10th and 11th, with 15ft to 8ft of swell, but it's all blown out and messy.
We finally get a bit of a breather mid-week. By Wednesday the 12th, the swell drops to 5ft, and the wind goes light and cross-off from the WNW. The energy is down to 589 to 774, which is weak, but the surf is clean. It's a marginal call, but it's the first real chance for a paddle.
Thursday the 13th stays clean with 4ft to 5ft of swell, but the size is small and the energy is down to 411 to 482. The best window in the first week, and honestly the whole forecast, looks like Saturday the 15th and Sunday the 16th. On the 15th, we get 4ft of swell from the SW with a period of 8 to 9 seconds, and glassy, clean conditions with light winds from the east and east-northeast at 10 to 15 km/h. The energy is low at 227 to 238, but it's the cleanest, most user-friendly surf in the entire 16-day window.
After that Sunday, it drops off. The rest of the run from the 17th through the 22nd is mostly small, weak, and blown out by cross-shore winds. There's a blip on the 21st with a jump in swell to 5ft, but it's from the SE, which is a poor direction, and the wind is a fresh cross-shore. It's a bit of a gap from the 17th to the 22nd with only marginal or poor options.
So, to sum it up: the standout is the weekend of the 15th and 16th. It's not big, but it's the cleanest, most manageable surf we've got. If you're an expert and want to stare down a monster, Saturday the 8th is a thing of legend, but you better be able to handle a 30ft wave. For everyone else, wait for that glassy window on the 15th or 16th.
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.
