The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the Ikei Island stretch over the next couple of weeks.
Right off the bat, I gotta be straight with you: the next week is a bit of a write-off for the most part. We’ve got a lot of tiny, weak swell and some pretty ordinary wind conditions. The first few days are just not worth suiting up for. We’re talking about a long gap of minimal activity from Tuesday the 21st right through to around Monday the 27th. The swell is barely there, mostly under 1ft, and the wind is all over the shop – onshore, cross-onshore, you name it. The combined energy is just a whisper, with figures like 28 and 43 (weak energy), meaning there’s simply no power in the water.
The first real glimmer of hope comes on Tuesday the 28th in the afternoon. We finally see a pulse of 4ft swell from the ESE with a decent period, and the combined energy jumps to 235 (moderate wave energy). The wind shifts to a clean offshore from the west, blowing at 9 mph. That’s the kind of setup that gets the heart beating a little faster. It’s forecast to be “good surf conditions,” but the overall score is still low. It’s a small window, but it’s the best we’ve seen by a long shot.
For Ikei Island, a reef break that’s fairly consistent, that clean offshore wind will be a major positive. The water temp is about average for this time of year, so no nasty surprises there. Just keep in mind, this spot can get a few people out there, so expect some company in the lineup.
After that little burst, things go flat again pretty quickly. The 29th and 30th drop back to tiny, weak swells, and the long-range stuff from the 2nd of August onwards is a complete mess. We’re looking at storm-force winds and huge, messy cross-shore conditions. The swell direction is all over the place, and the combined energy for the 5th of August hits 598 (strong wave energy), but with a short period of 8 seconds and fresh cross-shore winds, it’s going to be a lumpy, choppy nightmare. Honestly, that setup looks more like a kite-surfing day than a paddle-surfing one.
So, the standout for the entire forecast period is that Tuesday afternoon, the 28th of July. It’s the only window with a decent swell, clean offshore wind, and a chance of a few fun waves. It’s not a classic, but it’s the only real option on the table.
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.
