The Lowdown
G’day, I’m Rusty, and here’s the lowdown on Ikei Island for the next couple of weeks. We’ve got a wild start, then a long stretch of nothing, with a tiny flicker at the end.
First up, Thursday the 6th of August, we’ve got a 4m easterly swell, but the wind is a cross-shore at 22 mph, making it lumpy. The water’s warm at 87°, a touch warmer than usual. The combined energy is massive at 8416, but the conditions are just marginal. By the afternoon, the wind jumps to 25 mph, and it’s a total write-off.
Friday the 7th of August is a wild one. The morning brings a 6m swell from the NNW with a cross-off wind, but that wind is a gale at 43 mph, and the energy is 16253 – way too big for this break. The afternoon has storm force offshore winds at 59 mph, so you’re not getting out there.
From Saturday the 8th of August through to the 20th of August, we’re in a long, dry spell. The swell drops to under 2ft, often sitting at 2ft, with periods from 6 to 13 seconds, but the wind is relentless – cross-shore, cross-off, or onshore. The combined energy barely hits 284 on the best days. The water temp is off the charts, but the vibe is flat and messy. There’s a tiny moment on the afternoon of the 12th of August with a 2ft ENE swell and a gentle breeze, but it’s barely surfable. The break is inconsistent, and you’ll be waiting.
The first real chance is Thursday the 20th of August. The morning has a 6ft swell from the east at 9 seconds, with an onshore wind at 15 mph. The energy is 463, which is moderate, but the wind is onshore, so it’s bumpy. The afternoon is similar. For a break that’s usually fairly consistent, this run is a drag, but it’s normal for the area when the trades are blowing.
The best offering is the morning of the 20th of August – the biggest swell in a week at 6ft from the east, and the highest energy in the second week. But with onshore wind, it won’t be clean. The crowd situation at Ikei Island can be busy sometimes, but you won’t have to worry about that with this forecast.
Keep your stick handy – the ocean has a way of surprising us.
Rusty.

Information about the Ikei Island Surf forecast
The above surf forecast table for Ikei Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ikei Island can be found by selecting the local surf guide option on the grey menu. Our Ikei Island 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 (Ikei Island) 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 Ikei Island 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.
Ikei Island is 14 km (9 miles) from Gushikawa. If you plan a holiday in Okinawa, look for hotels and other accommodation in Gushikawa. Gushikawa has rooms for a wide range of budgets as well as car hire and transport links.
