The Lowdown
Right, lean in close, I’m Rusty, and I’m calling it straight from the sand.
Look, the next couple of weeks are a real struggle for us here. I’m looking at the whole 16-day window and honest to god, the surf is flat, tiny, and not worth paddling out for. The first good recommendation doesn’t even show up until Wednesday, July 30th, and even then, it’s barely a whisper. From now until then, it’s a long, dry gap of nearly two weeks with nothing but junk.
The only spot on the radar is Ikei Island, a reef break that’s fairly consistent but needs a solid push from the NE. For the first two weeks, you’re looking at ankle-snappers of 1ft to 1.5ft from the east, with weak combined energy (mostly under 100). The wind is mostly offshore or light, so the water will look clean, but there’s simply no energy to ride. The water temperature is sitting at 81°, which is a bit colder than usual for this time of year, so you might want a spring suit for the first session.
Now, as we push into the last few days of the outlook, things finally start to stir. Wednesday, July 30th, morning shows a jump to 4.5ft from the ESE, with a very long period of 16 seconds. The combined energy is chunky at 972 (moderate to strong), but the wind is onshore from the ENE at 9 mph. This is a groundswell, and while it’ll have some power, the onshore breeze will mess up the face. It’s also a touch big for beginners. For the afternoon, it’s 5ft from the same direction, but still with that onshore wind. The current just isn’t clean enough to call it a stand-out. The best you can say is that the swell is building, but the conditions are holding it back.
If you’re a hardcore local who just needs to get wet despite the chop, the 30th is your only real shot. For everyone else, keep your board in the car and wait for the next forecast.

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.
