G’day, Rusty here. Let’s break down what Ikei Island has in store over these next 16 days. The beginning is a bit of a snooze. From Friday the 3rd through Monday the 6th, we’re stuck with ankle-biters – around 0.6 to 1 ft – and cross-off breezes that just make things feel average. The energy is low (58), and it’s all very forgettable. Nothing to get excited about.
But come Tuesday the 7th, the ocean wakes up. The morning brings in a 5 ft groundswell from the ESE with a long 15-second period, and the energy jumps to a solid 884. The wind is light from the south, blowing cross-off, so the surface will be clean and inviting. The water’s running at 81°, a touch cooler than usual for this time of year. This is the window you want – a proper, clean session that’ll have some good lines for the intermediate surfer.
That Tuesday afternoon, the swell bumps up to 6 ft from the same direction, with an even longer 18-second period. The energy is now strong at 2250, but the wind shifts to a light cross, so you’ll have a few ripples on the water. Still very good waves, just not quite as glassy as the morning. My pick is Ikei Island on the morning of Tuesday the 7th – that’s the one to circle on the calendar.
Things get scary intense on Wednesday the 8th and Thursday the 9th. The swell jumps to 12 ft and then 16 ft from the SE, with period holding at 18 seconds. The energy is monstrous, peaking at 20,155. But the wind is onshore from the ENE and NE, so the surface will be messy and tough. This is heavy reef territory – strictly for experts with a death wish. And Thursday has a risk of thunderstorms too.
From Friday the 10th onward, it’s a ghost town. Strong easterly winds, cross-onshore, and then days of tiny, weak waves and poor conditions. The swell just shuts off, leaving us with flat, choppy water that’s more suited to a kite session than a paddle.
So, ride the wave on Tuesday the 7th if you can. After that, it’s a waiting game. That’s the read from here.
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.
