The Lowdown
Alright, this is Rusty, and I’m lookin’ at the next couple of weeks for Suicide Cliffs.
Honestly, to be straight with you, the 16-day window for Suicide Cliffs is a tough one. It’s a very consistent reef break that’s exposed to the swell, but for the first week, conditions are just not cooperating. We’re looking at about a week of crummy, poor surf with cross-shore winds and a lot of chop. The energy is weak, mostly in the 60-195 range, and the swell is small, around 1 ft to 3 ft, with a short period (8-9 seconds). It’s not doing anything. The water temperature is about average for this time of year, so no unusual conditions there.
The outlook starts to shift around Saturday the 22nd of August. The swell bumps up to 5 ft from the S, with a period of 9 seconds, but it’s onshore wind and the conditions are still marginal. The combined energy hits 505 (moderate). It’s a bit of a “maybe” session, but it’s not gonna be clean.
The best on offer is a bit of a stand-out period around Sunday the 23rd of August. The morning shows a 5 ft SW swell with a 10-second period, and the combined energy is 503 (moderate). The wind is light and cross-onshore, but it’s the cleanest we’ll see it for a while. Still, the tide conditions are questionable. By Monday the 24th, the swell is 5 ft from the SW with a period of 8 seconds, and the energy is 380 (moderate), but the wind is onshore, making it hard to get excited about.
After that, through the end of August and into the 31st, the swell drops back down. We see a few days of clean conditions with cross-offshore winds, but the waves are tiny, like 2 ft to 3 ft, with very low energy (65-245). The period is short (8-9 seconds). It’s just flat, man. The 30th of August afternoon shows a little spike: 5 ft SW swell with a 11-second period and energy at 595, but the wind is cross-shore and choppy, so it’s not a classic session.
For a beginner, there’s nothing here. The swell is under 5 ft, but the conditions are so poor that it’s not worth paddling out. For experts, the only window is the 22nd-24th, but the wind is messy. It’s a reef break, so the longer period swells (10-11 seconds) could offer some shape, but the wind will ruin it.
This is a dry spell for Suicide Cliffs. It’s not unusual for this spot to have long gaps with no good surf, and this is one of them. Hang tight, check the forecast again in a few days.

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.
