The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Ikei Island.
Right now, for the next several days, it’s pretty flat. We’re staring at a real lull, with nothing but tiny, weak swell showing up through to the end of July. From Saturday the 18th all the way through to Saturday the 25th, the surf is just not happening – we’re looking at waves around 1.0ft to 1ft from the east, with combined energy barely climbing past 60 (weak). The wind is often offshore or glassy, so it’s clean, but there’s simply no power behind it. This stretch is a write-off for surfing.
Then there’s a gap of a couple of days with still nothing worth paddling out for until things finally wake up.
The standout window looks like Monday the 27th and Tuesday the 28th. That’s where we see a real pulse of long-period groundswell. Monday morning brings a solid 6ft swell from the ESE with a very long 16-second period, and combined energy jumping to 1723 (strong). It’s a big, powerful swell – definitely expert territory at over 5ft. The wind is a gentle cross-shore, so there’ll be a little texture on the face. By Monday afternoon it hits 8ft from the ESE with a 15-second period and energy at 2241 (very strong), but the wind picks up to a moderate breeze, making for a cross-chop. Tuesday morning is cleaner, with 7ft swell from the ESE, a 13-second period, and a cross-offshore breeze, offering the better chance for a proper wave. This is a reef setup, and with that long period, the wave shape should be better defined and hold up nicely.
The water temperature is about 82°F, which is a bit cooler than average for this time of year – a couple of degrees off, so it’s noticeable but not crazy.
Crowds are listed as sometimes at Ikei Island, so you might share it but it won’t be a zoo.
So to sum it up: nothing for over a week, then a short, punchy window of big, powerful groundswell on the 27th and 28th. That’s your best bet, but only for experienced surfers.
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.
