The Lowdown

Alright folks, Rusty here. Let me tell you what’s cookin’ at Ikei Island.

To be straight with you, the first week and a half is a real bummer. From Wednesday the 22nd right through to the end of July, we’ve got next to nothing. The swell is tiny, mostly around 0.7ft to 2ft with short periods, and the wind is consistently cross or cross-onshore. It’s just poor surf conditions day after day, with a few storms and heavy rain thrown in for good measure. There’s a solid 10-day stretch here where you’d be better off doing something else.

Then, things get weird. On Saturday the 1st of August, the energy starts to pick up. The combined swell energy jumps to 376 (moderate) in the morning, then 671 (strong) in the afternoon, with swell coming from the ESE at 3ft to 4ft and a 13-14 second period. That’s got some push, but the wind is a fresh cross-shore breeze, making it lumpy and messy. Not worth paddling out for.

Now, Sunday the 2nd of August is where it gets interesting, but it’s a real tease. The morning shows a solid 7ft ESE swell with a 14-second period, and the wind is offshore from the ENE at 9 mph. That’s glassy conditions at a reef break that needs an offshore from the WSW? Wait, hold on – the wind is offshore from the ENE, which is a cross-offshore for this spot. But the combined energy here is 1934 (strong wave energy). The issue is the afternoon turns ugly, with a 8ft swell and a cross-onshore wind making it choppy.

But the real standout, the one that’s got my heart racing, is Monday the 3rd of August. The afternoon session is the only one in the whole outlook that gets a high score. We’re talking a massive 20ft swell from the east with a 16-second period (very long period groundswell). The combined energy is a whopping 18322 (very strong wave energy). The wind is offshore from the ENE at 12 mph. The report says it’s wind and tide favorable, but the swell is too big for this break. That’s a monster. Ikei Island is a reef, and with that long period, it’s going to be a freight train. This is for experts only. If you’re a charger, this is the day. The crowd profile says “sometimes,” so you might have a few other brave souls out there, but with swell that size, most will be watching from the shore.

Tuesday the 4th of August is even bigger, with a 43ft swell in the morning (combined energy 78449 – extremely strong) and a 31ft in the afternoon. Again, the report says it’s too big for the break. That’s a no-go zone unless you’re a tow-in hero.

The end of the window on the 5th and 6th of August drops back down to manageable 3ft to 3ft sizes, but the wind is still cross-onshore, so it’s back to poor conditions.

So, the one true standout is Monday afternoon, the 3rd of August. Ikei Island will be a beast. If you’ve got the skills, that’s your window. For everyone else, it’s a long wait for a wave that’s too big to ride.

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.
