The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Ikei Island.
First off, I gotta level with you. The next ten days or so are a write-off. We’re talkin’ tiny, gutless swell and onshore junk for most of it. From this Saturday the 18th right through to the end of the month, you’re looking at flat walls of water at best – 1ft – with a short period that just won’t get anything going. The combined wave energy is weak, mostly in the teens and twenties (11-63), and the wind is either onshore or side-offshore, but it doesn’t matter because there’s no power behind it. The few glassy moments on Wednesday the 22nd and Thursday the 23rd are a tease, with energy still barely cracking 58. It’s a real bummer of a stretch.
Then, towards the end of the month, things get dangerous, not good. On Monday the 27th, the energy starts to climb (107-364), but the wind is howling onshore at 25 mph, so it’s blown-out trash. By Tuesday the 28th, a big pulse of 7ft E swell hits, but the combined energy is a massive 1252-1282 – and it’s accompanied by a gale-force onshore wind at 40-53 mph. That’s not surfable, that’s a survival mission. The wind turns offshore on the 29th, but it’s storm force (56 mph!) with 7ft swell. You cannot paddle into that. Honestly, this setup looks more interesting for kite surfing than paddle surfing, if you’re into that kind of thing.
The one true standout is Sunday, August 2nd.
After a long, bleak wait, we finally get a window. The morning of Sunday the 2nd sees a solid 10ft groundswell from the NW, with a very long period of 13 seconds. The combined energy is a very strong 2669. This is serious, powerful swell – only for experienced surfers, no question. The wind is offshore out of the west at a moderate 12 mph, which will be clean and lined up. This is the one. Mark it in your calendar. It’s a long way off, so don’t bank on it, but if it holds, Ikei Island will be pumping with some proper, open-ocean waves.

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.
