Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s get straight into what’s shaping up for Suicide Cliffs. This is a spot that fires on a solid SW groundswell, and we’ve got a real mixed bag coming our way over the next couple of weeks.
First up, the immediate outlook is a bit of a flat spell. There’s nothing really worth paddling out for from Monday the 6th through to Wednesday the 8th. The swell is tiny, under 2ft, and the energy is weak (28-37). It’s a poor run of surf to start with.
However, things get absolutely wild from Thursday the 9th through to Saturday the 11th. We’re looking at a massive, long-period SE groundswell that will absolutely detonate on the reef. Swell heights are predicted to be massive – 18ft on Thursday morning, ramping up to a mind-boggling 35ft by Friday afternoon. The combined energy is through the roof (19,774 to 132,259), which is extreme. The wind, however, is a huge problem. It’s blowing a gale from the E and SE, hitting 31-34 mph, creating a total mess. It’s cross-shore and cross-onshore, so the surf will be completely blown out and dangerous. This is strictly for absolute experts only, and even then, it’s more likely a kite-surfing dream than a paddle-surfing reality. The raw power is there, but the conditions are not.
After that heavy pulse fades, we get a bit of a lull. Sunday the 12th has 10ft swell but onshore S winds, so it’s messy. Monday the 13th drops to 6ft with onshore winds, making it a marginal, low-quality day.
One of the best windows in the whole forecast lands on Tuesday the 14th. The morning is looking clean with a cross-offshore breeze from the ENE and a 4ft SW groundswell. The energy is moderate (451) and the wave state is listed as “clean”. It’s a small but fun day for the intermediate surfers, and the light wind will make for some nice, lined-up waves. The afternoon gets a bit riskier with a chance of thunderstorms. The water temp is about average for this time of year.
The following week from the 15th onwards is a bit of a mixed bag. Wednesday the 15th is small and middling, with a 3ft swell and clean cross-off wind in the morning. Friday the 17th afternoon is a potential sleeper, with a 4ft S swell going completely glassy with no wind – that’s a rare treat for a clean, if small, session. The weekend of the 19th and 20th is a write-off again with onshore winds and choppy, weak surf. The run ends on Tuesday the 21st with a small, clean cross-shore but not much power.
So, to sum it up: The standout is Tuesday the 14th morning. It’s the only day where the stars align for a clean, manageable, and pleasant paddle. The massive swell from the 9th-11th is a spectacle of pure power but is completely unsurfable due to the wind, so don’t plan on getting wet. Friday the 17th afternoon is a promising backup if you can snag that glassy window.
Rusty signing off.

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.
