Alright, I'm gonna level with you. Looking at this 16-day stretch for Ikei Island, it’s a total bummer. You’re not gonna find much to ride.
The only real action shows up on Friday, July 10th, but it’s a monster. We’re talking a 25ft to 28ft SE groundswell with a 17-second period, pumping out a massive 30744 to 40700 combined energy. That’s a whole lot of ocean moving. The wind is a screaming near gale from the east, just hammering it onshore. That’s a deadly combo, even for a spot that likes a NE swell. The water is a normal 84° for this time of year, so you won't be cold, but you will be in the washing machine. This is strictly for the big-wave pros – it’s way over 8ft, so beginners and intermediates need to stay well clear. It’s a blown-out mess.
Then the window goes dead. From Saturday, July 11th, right through to Thursday, July 24th, the swell completely disappears. We’re talking 14 days of flat to tiny, ankle-deep slop. The combined energy numbers are mostly in the single digits or low double digits – that’s nothing. There are a few days with a tiny 1ft to 1ft E swell, but the wind is often cross or onshore, just ruining the little bit of shape there is. The "poor surf conditions" note is all you need to know.
The one possible, and I mean *possible*, exception is the very last day, Saturday, July 25th. The swell is just about gone, with 2ft of weak ENE wind. The wind is a moderate cross-onshore breeze from the NE, so it’ll be choppy. It’s not really rideable. If you’ve got a longboard and a lot of patience, you might wiggle on a foam ball, but don’t get your hopes up.
This is a classic dry spell for this area. The forecasts can change, but right now, the only thing this coast is good for is kiting, especially with the strong winds on the 18th and 19th. For a surfboard, it’s a hard no.

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.
