Alright folks, Rusty here. Let’s take a look at what’s coming up for Ikei Island. The first week has a real flash in the pan, but after that, it’s a long stretch of ugly weather and blown-out conditions. We’ve got a solid window of clean, glassy surf early on, but you’ll want to be on it straight away because it gets grim fast.
Things kick off on Monday the 6th of July with small, clean waves. The morning sees a small 1ft swell from the ESE with a 17-second period, giving it that long, slow groundswell push. The water is a warm 83°, which is about average for this time of year. The wind is a light cross-off, so it’s surfable but a bit ordinary. By Monday afternoon, the swell picks up to 2ft from the same direction, wind goes offshore, and the energy jumps to a moderate 225. It’s an improvement. Tuesday the 7th is where it’s at. The morning is absolutely glassy with a 4ft ESE swell, a period of 13 seconds, and the energy is already building to 663. That’s a solid, clean setup. Tuesday afternoon is the real standout. The swell bumps to 5ft from the ESE, still a very long 16-second period, and the energy surges to 1104. The wind is glassy, and conditions are excellent for experienced surfers. The water temp is still that warm 83°. This is the best window of the whole 16-day outlook.
Now, Wednesday the 8th of July is where it goes sideways. The swell is a massive 10ft in the morning and 12ft in the afternoon from the ESE, with a very long 18-second period. The energy is astronomical – 5163 in the morning, 6786 in the afternoon. That’s a lot of power. But the wind swings onshore, and it’s a cross-on mess. The wave comment says marginal at best, and by the afternoon, it’s just poor surf. This is only for experts, and even then, the wind is going to ruin it.
From Thursday the 9th of July all the way through to Tuesday the 22nd of July, it’s a long, bleak run. We’re talking about a gap of nearly two weeks with no decent surf. The swell gets too big, then drops off, but the wind is relentless from the east and southeast, often at gale force. There are periods of risk of thunderstorms and near gale winds, creating a complete mess. The energy levels are either huge or zero, and the wind is always cross-onshore or onshore. There’s a brief flicker on Thursday the 16th of July with a 5ft E swell, but the wind is still cross-onshore, making it marginal at best. Don’t get your hopes up for that.
For the best session, you’ve got to be in the water on Tuesday afternoon the 7th of July at Ikei Island. That 5ft, 16-second groundswell from the ESE, with glassy conditions, is a proper treat. The water is a warm 83°, average for the season. Just be aware that with such a long period, the sets will have long gaps between them, and the paddle out might be easier, but the waves could be a bit straight at the beach. Still, that’s your best bet.
The rest of the run is a write-off, honestly. This setup looks more interesting for kite surfing than paddle surfing. Keep an eye on the forecasts, but for now, I’d say get your fill on Tuesday, because it’s a long dry spell after that.
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.
