The Lowdown
Alright, folks. Rusty here. Let’s get into it. The 16-day window is a real mixed bag – a long stretch of tiny, blown-out surf early on, building into a monster swell that’s only for the brave and the experienced. The standout is right at the end of the period, but it comes with serious power.
We’re starting with a long quiet spell. The first few days here at Suicide Cliffs (an exposed reef break) are a write-off. We’re talking about 2 ft to 4 ft of messy, short-period swell, mostly cross-onshore winds, and the combined swell energy is weak to moderate (41 to 154). The water temp is about average for the time of year so don’t expect any surprises there. This run of poor conditions stretches from the morning of the 18th of July all the way through to the 25th. There’s a brief moment of glassy conditions on the morning of the 22nd and 23rd, but the swell is so small (2 ft to 2 ft) with a weak period (6 to 7 seconds) that it’s barely breaking.
Then we hit a real rough patch. From the 26th of July onwards, the wind cranks up. By the 28th and 29th, we’re talking storm-force winds (59 to 62 mph) screaming off the land, which is cross-offshore and clean, but the swell is barely a ripple (1 ft to 1.0 ft). The energy is zero (0 to 12). It’s a huge gap with no real surf.
The action, and I mean *big* action, arrives on the 1st of August. The swell jumps to a massive 18 ft, coming from the west with a 10-second period. The combined swell energy is enormous (5483 to 5764). This is expert-only territory, no question. The wind is a strong offshore breeze (22 to 25 mph), so the waves will be clean and lined up, but it’s a serious paddle and a heavy reef. The best of the whole window is the Saturday afternoon session on the 1st of August. The wind is still fresh and offshore, the swell is solid, and the energy is peaking. This is the one to circle on the calendar. The 2nd of August sees a slight drop in size (15 ft) but the wind goes cross-shore, which will add some chop, making it still a dangerous, expert-only day.
So, looking at the whole 16 days: the first two weeks are a total dud. The only real standout, the only day worth paddling out for, is the 1st of August. A massive, clean, west swell at Suicide Cliffs. It’s a heavy, powerful reef break, and that’s not for the faint of heart. If you’re a beginner, stay well away. If you’re an expert, that’s your window.
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.
