The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks at Suicide Cliffs.
Right off the bat, I gotta be straight with you – for the first week and a half, there’s basically nothing going on. From now all the way through to Saturday the 26th of September, we’re looking at a long, flat gap. The wind’s clean enough, but without any real swell pushing in, it’s just a glassy lake out there. Don’t bother paddling out unless you’re keen on a flat-water paddle.
Then things finally start to get interesting. The first real sign of life shows up on the morning of Saturday the 26th of September, but this is not a session for the faint-hearted. A solid SE swell rolls in at 15 ft with a 12-second period. The combined energy is absolutely pumping at 5016 (strong wave energy). That’s a heavy, powerful groundswell, and with that period, it’ll be lining up and hitting the reef hard. The wind is a gentle breeze from the NNE, staying clean, but let’s be honest – at that size, this is strictly for experienced surfers. The crowds? At Suicide Cliffs, crowds are often a thing, but on a day like this, you’ll only see the crew with serious nerve out there. Water temp is about 84°, which is normal for this time of year, so you won’t need a thick suit.
Now, if you want the standout of the whole outlook, it’s the Sunday the 27th of September. Early morning sees a massive 21 ft swell from the SE, with a period of 11 seconds and combined energy hitting 9114 (very strong wave energy). That’s a beast. The wind is blowing offshore from the NNE at 16 mph, giving us clean, lined-up waves. But I’ve gotta add a major caveat: the guidance says this is predicted to be too big for this break. Even for experts, this could be closed-out on the reef or just plain dangerous. The afternoon drops to 15 ft, still solid, but with the wind picking up a bit, it stays heavy.
Monday the 28th of September stays big, but it’s dropping. Morning has 8 ft from the SE, but the period’s down to 8 seconds – short period windswell, less grunt. Combined energy is 1211 (moderate to strong). Still a solid day for experts. The wind remains offshore and clean. By the afternoon, it’s 7 ft SE, with energy at 680 (moderate), and the comment says “expect very good surf conditions,” so this might be the most user-friendly of the big days for advanced surfers.
After that, Tuesday the 29th of September sees the swell swing to the WSW at 5 ft with a longer 10-second period, but the wind cranks up to 19-22 mph offshore. The energy drops to around 466-520 (moderate). It’s clean, but the wind is strong, making it a bit messy, and the quality isn’t top-tier.
If you’re an expert looking for one day to circle, the morning of Sunday 27th is the most powerful, but it’s on the edge of being too much. For the best balance of size, shape, and wind, Monday 28th afternoon looks like the pick – clean offshore wind, dropping swell at 7 ft SE, and that “very good surf” call. That’s your window.
Stay safe out there.

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.
