The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
The start of this run is a beast. The real highlight is Saturday afternoon, August 8th, at Suicide Cliffs.
Saturday, August 8th – That afternoon is the one. You’re looking at a 28 ft swell from the SW with a 12-second period. That’s a ton of water moving. The wind is howling onshore at 47 mph, but the forecast says the wind and tide are favorable for the break. The combined energy is massive – 19358. This is for experts only; anything over 8 ft is getting serious, and this is way beyond. The water is sitting at 86°F, which is a touch warmer than usual for this time of year.
The Saturday morning is a write-off. The same strong SW swell is there at 23 ft, but with 50 mph SSW winds, it’s just a mess.
Sunday, August 9th – The swell drops to 13 ft on Sunday morning, but the wind is still strong and onshore from the S at 31 mph. Poor conditions. The afternoon is similar with 15 ft swell and 28 mph winds.
Monday, August 10th – The swell is still hefty at 12 ft in the morning, but the wind is a bit lighter from the SSE at 22 mph. Still, the surf quality is poor. The afternoon sees 8 ft with the same wind.
Tuesday, August 11th – Things start to settle. Morning swell is 7 ft from the SW with a period of 11 seconds, and wind is 16 mph from the SSE. Still not great, but the energy is dropping (1826). The afternoon goes to 6 ft with a 10-second period.
Wednesday, August 12th – A bit of a shift. The morning has 5 ft swell from the SW, but the wind is cross-shore from the W at 16 mph, creating a bit of chop. The afternoon is cleaner – 5 ft from the WSW, with a 9-second period and a light cross-offshore wind from the WNW at 12 mph. The energy is down to 649. It’s marginal, but the cleanest we’ve seen in a while.
Thursday, August 13th – Now we’re talking. The morning has 3 ft of swell from the S, with a period of 9 seconds. The wind is light offshore from the NNW at 9 mph. That’s gentle, clean, and glassy. The energy is only 361, but for a little wave, that’s solid. The afternoon is similar, with a light cross-offshore breeze.
Friday, August 14th – The morning is a bit cross-shore, but the afternoon cleans up again. 4 ft from the SW with a 8-second period, and a light cross-offshore wind from the WNW at 6 mph. Clean conditions.
Saturday, August 15th – Back to poor conditions. Swell is small, wind is light, but it’s onshore or cross-onshore. Not worth it.
Sunday, August 16th – The morning looks promising again. 4 ft from the SW with a 8-second period, and a light cross-offshore wind from the ENE at 6 mph. Clean. The afternoon gets a bit messy with a cross-shore wind.
Monday, August 17th through to the end of the forecast (August 23rd) – The swell stays small, mostly under 3 ft, with periods between 8 and 13 seconds. The winds are mostly cross-offshore or cross-shore, keeping things clean or slightly choppy. The energy is low, often under 200. There are no real standouts here. It’s small, weak, and the quality is poor. The 23rd Sunday afternoon sees a bit of a pulse with a 13-second period and energy of 410, but it’s still only 3 ft and the report says poor surf conditions.
So, the only true standout is the Saturday afternoon, August 8th, at Suicide Cliffs. That’s a big, powerful, expert-only wave. After that, the 13th and 16th mornings offer the cleanest small waves, but nothing to get too excited about.
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.
