Table - best surf conditions forecast for Suicide Cliffs over the next 16 days.
The Lowdown
Alright, let’s talk in feet and miles per hour. The main spot is Suicide Cliffs, a reef break that’s very consistent and exposed to the swell. Water temp is about normal for the season.
The first few days are a bit of a wash. Sunday the 6th has a 4ft SSW swell with a short period, but a fresh 19 mph NE cross-offshore wind is making it messy. The combined energy reading is 226, which is moderate, but it’s poor. Monday the 7th is smaller, 2-4ft, with winds still cross-off. Tuesday the 8th morning has a 3ft NW swell with a moderate offshore breeze, but it’s just surfable, not exciting. Wednesday the 9th is tiny, 1ft, with very weak energy (21).
Then there’s a big gap. From Thursday the 10th through Monday the 14th, it’s a mix of tiny, weak swell and onshore or cross-shore winds. Wave heights are mostly under 2ft. Not worth it.
The standout arrives on Thursday the 17th afternoon. The wind goes glassy, and a 6ft SE swell shows up with a combined energy of 363. That’s moderate to strong energy. The period is short, but the glassy conditions mean it’ll be clean. This is the best on offer. It’s over 5ft, so it’s for intermediates and up. Crowds are often here, so you’ll have company.
Friday the 18th and Saturday the 19th have onshore winds and lumpy conditions, with the swell holding around 5-6ft. Sunday the 20th is a 5ft S swell with cross-shore wind. Not great.
So, the call is clear: Thursday the 17th afternoon. Glassy, 6ft SE swell, clean conditions. That’s the one.

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.
