The Lowdown
Alright, listen up. Rusty here, giving you the straight talk on Suicide Cliffs for the next couple of weeks.
First off, I gotta be honest with you – it’s a rough start. We’re looking at a solid stretch of nothing much to get excited about. Sunday the 23rd kicks off with a 6-foot SW swell but that cross-shore wind is a buzzkill, making it choppy and messy. The water temp is about average for this time of year, so no surprises there.
Monday the 24th is a write-off with thunderstorms and more wind. Tuesday the 25th morning sees a tiny glimmer of hope – a 4-foot SW swell with a clean offshore breeze from the north. That’s surfable, but it’s small and ordinary. By the afternoon, it’s gone again.
Then things get wild, but not in a good way. Wednesday the 26th brings a massive jump in energy – combined energy hits 1120 – but it’s a 10-foot W windswell with gale-force winds. That’s a full-on washing machine. And Thursday the 27th? Forget it. A 15-foot to 21-foot SW groundswell with a 12-second period and a combined energy of 9030 and 12657 is just dangerous. The wind is onshore and the waves are huge and lumpy. This is expert-only territory, and even then it’s a hard pass. This setup is more interesting for the kite surfers than paddle surfers.
We finally get a window of opportunity on Friday the 28th. The swell drops to a still-chunky 15-foot from the SW, period is 12 seconds, and the wind eases to a gentle cross-onshore breeze. The combined energy is still strong at 5390. It’s still a big, powerful groundswell that will be breaking straight at the beach, but it’s clean enough to be the standout of the whole forecast. Get on it if you’re an experienced charger.
Saturday the 29th is smaller at 8-foot from the SSW, but it’s a bit messy with the cross-onshore breeze. The rest of the first week into the second week is a slow fade. From Sunday the 30th right through to the 7th of September, the swell is consistently under 5 feet, mostly with cross-shore winds. The energy is weak, with combined energy values mostly under 1000. The morning of the 7th of September looks clean with a 3-foot S swell and offshore wind, but it’s tiny.
So, to sum it up: the best bet is Friday the 28th for the big, clean, powerful swell. After that, the surf is small and average for the rest of the 16 days. It’s a long wait for a short window.
Rusty, signing off.

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.
