Alright, Rusty here. Let’s break down what’s happening at Ikei Island.
First thing: the next few days are a total bust. From Saturday the 4th through Monday the 6th, there’s next to nothing – swell running 1ft to 2ft from the east, combined energy is pathetic (42), and even though the wind is light, the ocean’s just flat. You’d be floating more than riding.
Now, Tuesday the 7th – that’s the day to circle. Morning turns on with zero wind, glassy water, and a 4ft groundswell out of the ESE, with a 13-second period. Combined energy hits 586. It’s clean and building. But the real magic is Tuesday afternoon: 5ft from the ESE, 17-second period, and energy jumps to 1346. It’s glassy, powerful, and that reef is going to be working. This is for the experienced surfers – over 5ft with that long period is serious. Water temp is 81°F, a little cooler than average, but nothing crazy.
Wednesday the 8th gets heavy. Morning brings 10ft from the ESE, 18-second period, massive energy (6402). But the wind turns cross-onshore and it gets choppy – only for the brave. By afternoon, 12ft and onshore winds ruin it. Thursday the 9th and Friday the 10th are a full-on blowout with huge swell over 16ft and gale-force winds – dangerous and ugly.
From there, it’s back to tiny, poor conditions through the 19th. A few 3ft pulses around the 17th and 18th pop up, but with short 6-second periods and onshore wind, it’s not worth getting wet.
Bottom line: Tuesday the 7th afternoon is your one standout. Clean, powerful, long-period groundswell, glassy wind – that’s the session to chase if you’ve got the chops. The rest of the run is dry.
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.
