The Lowdown
Alright, this is Rusty, and I’m looking at what’s on offer for Suicide Cliffs over the next couple of weeks.
First up, for the next few days, it’s a bit of a write-off. Monday the 31st of August through to the 8th of September is mostly poor, with no real surf to get excited about. The wind is all over the place, mostly cross or onshore, and the swell is small and messy. The water temperature is about average for the time of year, so no surprises there.
Things start to shift around Wednesday the 9th of September. The swell picks up a little, with cross-offshore winds starting to clean things up. It’s still marginal, but the morning of Thursday the 10th sees a 7ft SSW groundswell, period of 12 seconds, and those cross-offshore winds from the NE making for clean conditions. The combined wave energy is moderate (1290). This is a decent option for intermediate surfers, but it’s not a standout.
The real standout comes later. Friday the 11th of September afternoon, the swell jumps to 12ft from the S, period 14 seconds, with cross-offshore ENE winds at 12 mph. The water gets a bit lumpy, but it’s clean. The combined energy is strong (5023). This is getting into expert territory now, as it’s well over 8ft. Saturday the 12th, the swell is even bigger, 16ft to 18ft, with a 14-second period. The combined energy is massive (9967). This is big, powerful, and only for the experienced. The long period means it’s best suited to the reef setup here, as it’ll break a bit too straight for a beach break.
Sunday the 13th of September afternoon is the biggest of the lot, with a predicted 31ft SSE swell, 15-second period, and combined energy of 40325. That’s a massive, powerful swell, but the wind is a fresh cross-shore, making it lumpy. The file says it’s too big for this break, and I’d agree – this is a serious, expert-only event, and even then, it’s marginal.
The period from the 14th to the 15th of September continues with huge swells, but the wind remains cross-offshore, so it’s clean. The 36ft S swell on Monday the 14th morning is still too big, but the 28ft SW swell on the afternoon is a bit more manageable, though still huge. Wind is ENE at 19 mph, cross-offshore, so it’s clean. The 20ft W swell on Tuesday the 15th morning is also huge, with a strong breeze from the NE.
Overall, the best for most surfers will be the window from Thursday the 10th to Friday the 11th of September, with the 7ft to 12ft swells and clean conditions. If you’re expert and looking for a big, powerful wave, the afternoon of the 11th is your best bet. The later stuff is just too big for this spot.
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.
