The Lowdown
Alright, Rusty here. Let’s break down what’s happening in our zone.
I’ll level with you: we are in a long, quiet stretch right now. Not much to get excited about until the tail end of the 16-day window.
The only wave that has any real pulse is Suicide Cliffs, a consistent reef break that needs a proper push to work.
Water temp is around 83°, so no real surprises there for this time of year.
Starting with this Saturday the 12th: weak and messy. You’ve got a 3ft SE windswell but with only 6 seconds between bumps, and a cross breeze chopping it up. Energy is barely noticeable at 56. Not worth the paddle.
Sunday the 13th brings 4ft from the east, still that short 6-second period. The wind goes clean, but the wave itself lacks any punch – call it weak. The whole rest of the week – the 14th, 15th, 16th, and 17th – is flat to ankle-high. Zero action.
Mid-week is even worse with gale force and storm force winds blowing through, but there’s still no swell to ride anyway. A total write-off.
The first real hope shows up on Saturday the 26th of September. We finally see a 2ft SW groundswell, but this time it’s got a long 12-second period. That’s proper groundswell energy. The combined energy is moderate (73), winds are light and off-shore, so the face should be clean. The afternoon bumps up to 2ft from the SW with 84 energy – still small, but easily the best in this whole forecast. It’s clean, lined up, with a glassy surface that afternoon.
Sunday the 27th keeps that good vibe going: 2ft of 10-second SW swell in the morning with offshore breezes. The afternoon goes dead glassy. Tiny but clean. For a longboard, that’s a winner.
So, to cut it short: the first week and a half is dead. If you want a wave, pencil in the last Saturday and Sunday of the month. Before that? This setup looks more like kite-surfing conditions. A tough run, but it’ll turn around eventually.
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.
