The Lowdown
Alright, this is Rusty comin' at ya from the surf check. Listen, we gotta be straight up with each other. The next couple of weeks are a real mixed bag, and you're gonna have to be patient. The swell window is wide open, but the wind is gonna be a pain in the arse for most of it.
The first real bit of action we're looking at is Suicide Cliffs, and it's a classic case of "so close, yet so far." The water temp is sittin' at a warm 84°, about average for this time of year, so you won't need the thickest rubber.
The opening days from the 18th through the 21st are a write-off. We've got tiny swell, under 3ft, and the wind is howling from the east and southeast, creating lumpy, choppy, cross-shore junk. It's not worth paddling out for.
Now, we get a glimmer of hope on Saturday the 22nd. The morning is still messy with a cross-shore wind, but hold on for the afternoon. The wind swings around to the west-northwest, going light and cross-offshore. We've got a solid 7ft of SW groundswell pumping in, with a moderate combined energy of 1406. The period is 10 seconds, so it's got some push. The report says it's excellent for experienced surfers. This is the one true standout in the first week. Suicide Cliffs with that clean offshore wind and a solid SW swell is gonna be a proper session. Keep in mind, this spot can get crowded, and it's a very consistent reef break, so you'll be sharing the peak.
But don't get too excited. The next day, Sunday the 23rd, the wind turns back onshore from the southeast, and the swell gets lumpy again. Monday the 24th is the same story with a strong cross-shore ESE wind. The surf is there, but it's messy.
We get a few small, clean days from the 25th to the 28th, but the swell drops right off. We're talkin' tiny 2ft to 3ft waves with glassy conditions. It's surfable, but straight-up ordinary. Not worth a special trip.
Then, we hit the big one. From the 29th of August through to the 1st of September, the swell goes absolutely mental. We're talkin' 20ft to 26ft of swell with a very long period of 14 to 16 seconds. The combined energy readings are off the charts, hitting 30,995 and even 52,258. The wind is offshore, the conditions are clean, but the forecast is clear: this swell is predicted to be too big for this break. This is not a paddle session, my friends. This is a "watch from the cliff" or "rig up the kite" situation. For a beach and reef setup like this, that kind of power with that long period is just a washing machine for most surfers. Only a complete lunatic with a death wish would be out there.
Finally, on the 2nd of September, Wednesday morning, the swell drops to a still-massive 18ft to 20ft, but the wind goes light and cross-offshore, and then glassy. The report says it's "exceptional surf conditions for expert surfers." This is your second standout. If you are an expert, that Wednesday morning is the window. The swell is still huge, very long period from the SSW (13 seconds), and the conditions will be perfect. But I cannot stress enough, this is for experts only. Anyone else, stay on the beach.
So, to wrap it up: The first week is mostly a bust. The standout is Saturday the 22nd afternoon for the experienced crew. Then we have a long gap of small, ordinary surf. The second week brings a massive, dangerous swell that is too big for the spot, followed by a final window on the 2nd of September for expert-level surfing only. Be patient, pick your moment, and don't be a hero.
Rusty, out.

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.
