The Lowdown
Alright, Rusty here. Let's chew the fat on what's coming our way over the next couple of weeks.
First off, the water's running about 29°, which is dead average for the season, so no surprises there.
We're staring down a pretty grim start. From Thursday the 27th right through to Tuesday the 1st of September, it's a flat spell. The swell is tiny, the wind is a mess, and the wave energy is weak, barely scratching triple digits. It's a full week of nothing doing.
Then things get wild, but it's a double-edged sword. On Tuesday the 1st of September, the swell hits hard, but it's a monster. We're talking a 23-foot swell from the SE with a combined energy of 11,244. That's not just big, that's a beast. The wind is cross-shore, but it's honestly too much water for Suicide Cliffs. The guidance says it's too big, and I'm with that. It's a day to watch from the cliff.
Wednesday the 2nd is a bit more manageable, with a 8 to 10-foot SSW swell, but it's still a solid, powerful groundswell with an 11-second period. The combined energy is still strong at 1,714 to 2,469. The wind is a clean cross-off shore, so the conditions will be beautiful, but the wave size is pushing into expert-only territory. It's a "marginal" call, so only for the very experienced.
The real standout, and the one I'd circle on the calendar, is Thursday the 3rd of September. The morning shows a 21-foot S swell, and the afternoon jumps to a massive 30-foot S swell with a 12-second period. The combined energy hits an insane 23,651. Wind is offshore and clean, which is a gift. But let's be real, this is a life-or-death kind of day. It's a true expert-only, big-wave session. For the rest of us, it's a spectator sport.
Friday the 4th of September is still pumping, but down to a more manageable 13 to 16-foot W swell. The combined energy is still strong at 2,823 to 5,132. The wind stays offshore, and the conditions are clean. This is the best window for experienced surfers, with "exceptional" conditions noted. It's still big, but it's a step down from the chaos of Thursday.
Saturday the 5th of September sees the swell drop to 7 feet from the W with a shorter 7-second period. The combined energy falls to around 600, which is much more moderate. The wind is light and cross-off, making for clean, fun waves. This is the best day for intermediate surfers, with "very good" conditions. It's a solid session.
Then it's back to the doldrums. From Sunday the 6th through to Friday the 11th of September, the swell drops right off, the energy is weak (under 350), and the waves are small. It's a long, flat spell to end the forecast. The wind is often clean, but there's just no swell to work with.
So, the pick of the litter is Thursday the 3rd of September for the big-wave crew, and Friday the 4th for the experienced. Saturday the 5th is the one for the rest of us.
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.
