The Lowdown
Alright, mate, Rusty here. Let’s get into it. We’ve got a single spot on the radar for this stretch: Suicide Cliffs – a solid, very consistent reef break that’s exposed to the swell. The water's sitting at a balmy 86°F, which is a touch warmer than usual for this time of year – nice for a session in boardies.
Right now, we’re not looking at any good surf for a long while. We’re stuck in a real dry spell with poor conditions and zero scores until mid-week. There is plenty of size early on – we’re talking 12ft to 13ft of swell from the south with a decent 10 to 11 second period, and the combined wave energy is massive (4611 to 4077). But the wind is howling from the SSE at 25 mph, turning it into a messy, stormy mess. The risk of thunderstorms is high, so leave the boards on the rack. This continues through Sunday and Monday.
By Tuesday the 11th, the swell drops to 6ft and the wind eases a bit, but we’re still getting cross-onshore chop. The combined energy is moderate (1087). It’s only a marginal call at best, and that’s the first hint of anything remotely rideable but honestly, it’s still not worth paddling out for.
The first real glimmer of hope comes late on Thursday the 13th in the afternoon. The swell is small, only 4ft from the southwest with a short 8-second period, and the combined energy is weak (299). But here’s the kicker – the wind drops right off to glassy conditions. For a reef break like Suicide Cliffs, glassy is gold. It’ll be clean, but tiny. This is the only standout window in the whole 16-day run, so if you’re desperate for a slippery, small-wave glide, that’s your moment. Don’t expect much power.
From there, it’s back into the doldrums. Friday the 14th through the start of the second week sees the swell hovering around 4ft to 4ft, but the cross-onshore wind comes back, and it’s just choppy and poor. The middle of the second week is even worse – by Wednesday the 19th and Thursday the 20th, the swell drops to under 3ft, and the combined energy is barely a whisper (as low as 72). The wind turns cross-offshore and the conditions clean up, but there’s simply no wave height to work with.
We finally see a bit of a pulse return on Sunday the 23rd with a 6ft south swell and an 11-second period. The combined energy jumps back up to 690, but the wind is straight onshore and strong at 25-28 mph, so it’s just blown-out and messy. No good for a paddle, but if you’ve got a kite, it might start looking interesting.
So bottom line – the entire 16-day window is a bust except for that one glassy afternoon on Thursday the 13th. If you can sneak out for a tiny, clean session on the reef, that’s your best bet. Otherwise, it’s a long wait. Forecasts can change, but right now, it’s looking grim.
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.
