The Lowdown
Alright, crew, Rusty here. Let's get into it.
The next couple of days are a total flat spell. We're looking at a bit of dribble, nothing with any real push, so it’s probably best to find something else to do for the first part of the week. Then, things get properly wild.
By Friday the 7th, the ocean’s gonna wake up with a serious roar. We've got a solid, clean building swell at Suicide Cliffs (Hawaii), but it's going to be a raw, powerful one. The energy readings are off the charts – up to 6873 in the morning. It’s not just big; it’s going to be massive, with the swell cranking 20ft at 10 seconds. By the afternoon, that jumps to a mean 30ft with an 11-second period, and that’s just the start. The wave energy value hits a scary 20737. This is not a day for the faint of heart. The wind is going to be ripping with storm-force gusts, so while it’s clean, it's going to be a battle to even get out. This is heavy, expert-only territory.
Saturday the 8th is when it truly maxes out. The swell peaks at an enormous 43ft to 48ft on Saturday afternoon, with a strong 14-second period. The combined energy is just staggering – values like 63480 and then 82317. This is a life-changing, horizon-bending kind of swell. The wind is howling, going from gale-force to a full-on cross-shore on Saturday afternoon, which will make for some crazy, freight-train waves. This is purely for the most experienced big-wave chargers; for everyone else, it’s a spectator sport. It’s way over the 8ft mark, so it’s only for those who truly know what they're doing.
Sunday the 9th and Monday the 10th will still be huge and dangerous. We're looking at 21ft to 23ft swells with strong onshores and hurricane-force winds on Sunday morning. It stays unruly and blown out, and while the size remains considerable, it’s not going to be clean.
The swell slowly backs off through the middle of the next week, but the wind turns onshore, making things a stormy, lumpy mess. By Wednesday the 12th, it's still a solid 11ft to 13ft but with a fresh to strong cross-onshore, so expect some chop and mess.
Now, looking further into the horizon, there’s a light at the end of the tunnel. Things start to get interesting around Thursday the 13th, when the swell drops to a more manageable 8ft to 8ft, but the conditions are still questionable.
The standouts for clean surf are on Friday the 14th and Saturday the 15th. After all that chaos, the ocean finally settles. We're looking at a solid 5ft to 6ft of SW swell on Friday with those long 11-second intervals, and the wind goes light offshore. The energy is still moderate at 784, but the quality will be there. It's still going to be a bit hefty for beginners, but it's a proper, clean wave with good shape. Saturday sees a slightly smaller, but still fun 4ft to 4ft SW swell with a 10-second period. The wind is offshore and light, and the energy is around 339-340. These two days look like the best, cleanest waves on offer.
The surf gets smaller into the second week, with waist-high options and moderate winds, but it's all pretty average. The energy is weak, and it looks like conditions to just have a fun, mellow session rather than anything epic.
The water is sitting at 87°, which is a touch warmer than the long-term average for this spot at this time of year – not a big deal, but you’ll feel it.
So, to sum it up: the start is a bust, the middle is a wild, monster swell that only the elite will touch, and the weekend of the 14th and 15th looks like the window for some proper, clean waves.
Rusty out.

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.
