The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Ikei Island over the next couple of weeks. I’ve got to be straight with you – this forecast is a real mixed bag, and for a lot of it, you’re going to be watching from the sand rather than riding.

The first usable waves show up on the morning of Sunday, the 2nd of August, but honestly, it’s barely a ripple. We’re looking at a tiny 1ft swell coming out of the ESE with a very long 19-second period. That long period means it’s got some legs but the size is just too small. The wind is a light cross-onshore from the NNE at 3 mph, which is not helping. The combined wave energy is weak at 142. Water temp is sitting at 87°, which is a touch warmer than normal for this time of year, so at least the water feels good even if the surf doesn’t.

The real action, and I mean *real* action, kicks off on Sunday afternoon. That’s the standout of the whole outlook. The swell bumps up to a clean 2ft from the east, with a 17-second period, and the wind goes completely glassy – zero mph. That is a rare treat. The combined energy jumps to a moderate 235. This is the window to get out there. It’ll be small, but absolutely clean and fun on a log. Crowds are possible here on a day like this, so get out early.

Monday the 3rd of August sees the swell building. We get 4ft from the east in the morning, with a period of 15 seconds, but the wind swings around to a cross-shore from the north at 9 mph, bringing some chop. The energy is getting stronger at 655. The afternoon is a bit bigger at 4ft but with more cross-onshore wind and chop, making it less appealing.

Tuesday the 4th and Wednesday the 5th see the swell really start to pump, but the wind turns ugly. We’re looking at 5ft to 11ft of east swell with periods around 17-18 seconds. This is proper groundswell, and on a reef break like Ikei Island, it could be great. But the cross-onshore wind from the NE at 9-16 mph is going to make it choppy and messy. The energy gets strong, hitting 1726 on Tuesday morning and a whopping 7049 by Wednesday afternoon. The waves are there, but the quality is poor.

Now, Thursday the 6th of August gets wild. We’ve got massive 18ft swell from the east, a 19-second period, and the combined energy is over 20,000 – that’s very strong. But the wind is a strong cross-shore from the NNW at 25-31 mph. This is expert-only territory if you even try it. Honestly, with how big and messy it’s going to be, this setup looks more interesting for kite surfing than paddle surfing. Friday the 7th is even worse, with a 33ft swell and violent storm-force winds. Stay home.

We get a brief drop on Saturday the 8th of August, with a 11ft swell from the NNW but the wind is still cross-shore. The following Sunday the 9th through to the end of the outlook is a write-off. The swell drops right off to under 3ft, and we get storm-force winds, gale-force winds, and messy conditions all the way.

So, to sum it up for Ikei Island: Your one and only real chance to get a clean wave is Sunday afternoon, August 2nd. That glassy 2ft east swell is the pick of the bunch. After that, it’s either too messy, too windy, or too dangerous until the outlook runs dry. The second week is a complete bust, with nothing but poor conditions and no rideable surf.

Stay safe out there.

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.
