Alright, let’s get into it. Rusty here.
Right now, we’ve got a long, flat spell ahead. From now through the 23rd, most of it is either tiny or blown out by onshore winds. The 13th and 14th have some swell, but it’s from the SSE and S with the wind right on it – just a choppy mess. There’s a little bump around the 18th with some 4 to 4 ft WSW swell, but the energy is weak (combined energy in the low 200s). Cross and cross-off winds help a bit, but it’s not worth paddling for.
Then we hit a real dry spell from the 20th through the 24th. The 21st jumps up to 8 ft from the SSW with a 12-second period, and the energy climbs to 1431 in the morning, but the onshore ESE wind at 12 mph chop it up badly. The guidance says marginal at best. Water temp is 85°, pretty normal for the time of year, but that doesn’t fix the surf.
Now, here’s the real one. Sunday July 26th – mark it. Suicide Cliffs (reef) comes alive. Morning: 8 ft from the SE at 11 seconds, with a light offshore N wind at 3 mph. That’s glassy, clean, and perfect for the exposed SW-facing reef. Combined energy is 1842 – strong. Afternoon gets even better: 10 ft SE swell, same 11-second period, but the wind goes glassy – flat calm – with 2126 energy. That’s a session for the books. Big waves, so experts only. Crowds are likely here when it’s good.
Monday July 27th pushes into serious territory. Morning: 12 ft from the SSE at 12 seconds, glassy with a light NW wind. Energy is 3372 – massive. This is a long-period groundswell, and it’s going to be powerful on the reef. Afternoon sees 15 ft from the S at 11 seconds, but the wind swings ESE cross-shore. Still looks clean, but with 5042 energy, it’s absolutely pumping. Only for expert surfers who mean business.
Tuesday July 28th holds size: 13 ft from the SW at 10 seconds, with clean cross-off ENE winds. Morning is excellent for experts; afternoon is a little messier but still powerful. Water temp stays around 85°, which is just average for July.
So to wrap it: the first two and a half weeks are a solid bust. Save your energy for the last weekend into the following Monday. Sunday 26th, Monday 27th, and Tuesday 28th are your windows. Suicide Cliffs is the only spot that fires, and when it does, it’s a proper big-wave session.
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.
