The Lowdown
Alright, let’s break it down. The short story is, you’ll be waiting a while before things get interesting.
Right now and for the next week, it’s dead flat. From Friday 11th through to the end of the week starting 14th September, the swell is tiny, mostly under 3 feet, from weak directions like NW, SE, and S, with short, weak periods around 6 to 8 seconds. The combined energy is under 100 (33 to 82). Winds are cross or cross-off from the east, keeping things clean, but with that little push, it’s not worth paddling out. There’s a solid gap of nearly a week with nothing.
Come Monday 21st September, everything changes – and I mean everything. A massive pulse hits. Monday morning sees a 21-foot swell from the SE with a very long 14-second period, and the combined energy is enormous (17,100). By Monday afternoon it’s 24 feet and 15 seconds (24,640 energy), with offshore winds from the north at 43 to 56 mph – gale to storm force. You can’t paddle into that. This is for the absolute elite only.
Tuesday 22nd is even bigger: 39 feet from the SE in the morning, 41 feet from the SSE in the afternoon. Winds shift to cross and cross-off, but at storm force, it’s a total mess. Wednesday 23rd stays huge, with 34-foot to 31-foot swells and strong winds from the west. This stretch is way too big for Suicide Cliffs – it’s a reef break, and these sizes are only for the most experienced.
Things settle toward the end of the 16-day window. Thursday 24th and Friday 25th September drop to 13-foot to 8-foot swells from the WNW and NW, with periods around 11-12 seconds. Winds become light offshore from the NNE. The swell is still solid, over 8 feet, so expert territory, but the combined energy drops to moderate (1,365 to 4,153). The wind is light and offshore, so it’ll be clean.
The standout is Friday afternoon, 25th September. Swell 8 feet from the NW, period 11 seconds, light offshore breeze from the NNE at 6 mph. The water temperature is around 83°F, which is average for this time of year. Crowds at Suicide Cliffs can be a thing, but with this size, it might thin out. This is your best bet if you’ve got the skill.
Saturday 26th September morning also looks decent: 10 feet from the NW, period 8 seconds, light offshore. The period is shorter, so it’ll be a bit less powerful, but still clean and punchy for the experts.
Bottom line: a long flat start, then a massive, dangerous pulse mid-week, and then a couple of good, clean, heavy days for experienced surfers at the very end. Keep an eye on the forecasts, because that last weekend might just fire.

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.
