The Lowdown
Alright, let's switch to feet and Fahrenheit. Rusty here again.
So, Suicide Cliffs (reef) is the only game in town, and it's a rough one. The first week is a total bust. From Monday the 24th through to Sunday the 30th of August, it's a complete dead zone – a solid week of poor surf. You can leave the board in the garage.
We scrape a little life on Monday the 31st of August afternoon. The wind goes cross-offshore and it's clean, but it's a marginal call. There's a 10ft swell from the SE, with a combined energy of 2476, but it's not quite on.
Then Tuesday the 1st of September gets wild. The morning is still iffy with a 10ft SSE swell and a 12-second period. The afternoon though? A massive 28ft SE swell with a 14-second period and a combined energy of 27801. That is a monster. But the file says that's too big for Suicide Cliffs. Only the absolutely crazy experts should look at it.
Wednesday the 2nd of September is better. The afternoon has a 10ft SSE swell with a 9-second period. The wind goes offshore from the NNE, and it's "excellent surf conditions for experienced surfers." Clean, offshore conditions. That's the pick for the confident crew.
Thursday the 3rd of September is another one. The morning has an 12ft SSE swell with offshore winds, perfect for the experienced surfer. The afternoon holds with a 10ft S swell. Both are clean and moderate offshore.
After that, Friday the 4th and Saturday the 5th of September drop off into smaller, more ordinary waves. Sunday the 6th is tiny and glassy.
Looking to the second week, the big standout is Monday the 7th of September morning. A 15ft south swell with a long 13-second period. Combined energy jumps to 6339. The wind is a gentle offshore from the NNW. This is labelled as "exceptional surf conditions for expert surfers" – a score of 7. It's a week away, so it's promising but not locked in. The afternoon that day hits 18ft from SSE but has a tide issue.
Tuesday the 8th of September morning sees another massive 20ft swell from SSW at 13 seconds, with an energy reading of 11677. Clean cross-off winds, but again, only for the hardcore.
So, first week is a complete miss. For the experts, the key windows are the afternoon of Wednesday 2nd of September, the mornings of Thursday 3rd and Monday 7th of September. Get it while it's good.
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.
