The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Suicide Cliffs over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a long, flat spell ahead. The first real, rideable surf doesn’t show up until the morning of Friday, August 7th, and even then, it’s an absolute monster. We’re talking about a massive groundswell from the west-northwest piling in at 34 ft with a 12-second period. The combined energy is a staggering 30,666 – that’s not just strong, that’s out of control. The wind is ripping hard out of the northwest too, so it’ll be clean, but the problem is the size. This is not for the faint of heart. At that size, Suicide Cliffs is a strictly expert-only zone. You’d need a death wish and a bigger pair of fins than I’ve got.
That swell peaks on the afternoon of the 7th, with the swell shifting to the west-southwest, hitting 41 ft and a 13-second period. The energy jumps to 52,480. The wind is still howling, though it’s more cross-offshore. This is as big as it gets, and it’s only for the absolute elite.
The water temperature is sitting at 86°, which is a touch warmer than normal for this time of year – feels like a warm bath out there.
Now, the real kicker is that after that first pulse, the whole setup turns ugly. The wind swings hard onshore from the south-southwest from Saturday the 8th onward, and while the swell stays big (16-20 ft), it’s going to be a messy, blown-out battlefield. The energy drops, but it’s still a churning mess. The whole second week, from the 8th through the 15th, is plagued by onshore winds and dropping swell. It’s a write-off for any kind of clean, surfable wave.
So, the standout is that Friday, August 7th window. If you’re an expert hell-bent on a big, clean face, the morning is your best bet, but be ready for a serious beating. For everyone else, this is a long stretch of no-go.
Stay safe out there.
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.
