Alright, let’s switch that over for those who think in feet and mph.
Don’t get your hopes up just yet. We’ve got a long flat spell through the first week. Tiny waves – about 1 foot or less – with poor conditions all the way until the morning of Wednesday the 9th. A real dead stretch.
Then the ocean wakes up in a big, scary way. Starting Thursday the 9th of July, a massive, long-period groundswell from the SE shows up, going from 20 feet up to 33 feet a day later. The combined energy numbers are insane – 20292 and later over 100,000 – that is an enormous amount of power coming in on a 17-18 second period. For Suicide Cliffs, a reef break, that is strictly for experts. Anything over 8 feet is big, and over 12 feet is expert-only. The wind Thursday and Friday is clean and cross-offshore, but the swell is just way too big for a sensible paddle.
Saturday the 11th is still a burly 21 feet, but now the wind is blowing cross-onshore and messy. It gradually drops into the 6-10 foot range by Monday the 13th, but the wind is all over the place, leaving lumpy conditions.
The second week looks cleaner but smaller. By Friday the 17th of July, we’ve got clean glassy conditions with cross-offshore wind and 5-6 foot swell from the S/SW. That’s the best of the later period – not huge, but clean and rideable. Sunday the 19th has a nice offshore breeze with 4-5 foot SSE swell, but the period is shorter (8 seconds) so less push.
The one to circle is the morning of Thursday the 9th of July. For the big-wave crew only: 20-foot SE groundswell (18 second period) with clean cross-offshore NE wind at 22 mph. It’s going to be terrifying and perfect. For the rest of us, that’s a spectator day.
Stay safe,

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.
