Alright, this is Rusty, and I’m looking at what’s on the cards for Ikei Island over the next couple of weeks. It’s a reef setup that needs a specific easterly kick to really work, and for the first few days, we get a beautiful taste of what this place can do.
The session kicks off on Tuesday, July 7th. The morning looks fantastic, with a clean 4ft swell rolling in from the ESE at a long 13 seconds, and a light cross-offshore breeze tidying up the surface. The water is sitting at a very warm 83°, which is dead average for this time of year, so it’s your usual tropical bathwater. The real standout, and the best on offer in the whole window, is Tuesday afternoon. The wind goes completely glassy, and the swell jumps to 5ft from the ESE with a very long 16-second period, pumping out excellent energy. This is classic Ikei Island form—long period groundswell wrapping nicely around that reef.
Wednesday the 8th starts to get tricky. The morning shows 8ft of ESE swell, still with that lovely 16-second period, but the wind swings onshore from the NE, mixing things up. By Wednesday afternoon, it’s blown out with 10ft on offer. The swell keeps growing through Thursday and Friday, the 9th and 10th, but so does the wind. By Friday the 10th, we’re looking at a massive 28ft to 31ft swell with near gale-force winds. That's way too much juice for this break, and for 99% of surfers, it’s a hard pass. Honestly, with that much wind and that kind of energy, it’s looking more like a kite-surfing setup than a paddle session.
After that, the ocean goes quiet for a long stretch. From Saturday the 11th right through to Thursday the 16th, there’s barely a ripple, with tiny waves and messy, lumpy wind conditions. It’s a real dead period.
We get a bit of a flicker again on Friday the 17th, with a bump in size up to 7ft, but the wind isn’t cooperating. The next real hope comes on Saturday the 18th. The early morning shows a clean 6ft swell from the E at 10 seconds, with a light cross-offshore breeze. The energy is moderate and the surface is clean. It’s a solid option, but not quite the glassy perfection of that Tuesday.
This break can be a total gem, but it’s not for the faint of heart—crowds are a possibility here, and the reef demands respect.
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.
