The Lowdown
Right, let’s have a look at what’s cookin’ for Ikei Island over the next couple of weeks. Gotta be honest with ya, it’s a slow start, real slow.
First up, we’ve got a long stretch of flat or tiny, weak surf from Tuesday 28 July right through to Sunday 2 August. You’re lookin’ at maybe 0.7ft to 1ft, period under 11 seconds, and the combined energy is barely a whisper – we’re talkin’ numbers like 33, 48, 31 – all under 100 (weak energy). The water temp’s sittin’ around 85°, which is pretty average for the time of year, no big wobble there. There’s some glassy mornings in there – Wednesday 29 and Thursday 30 July are dead calm – but with no real swell to work with, it’s just a flat lake out there. Not a single good wave in this whole first week.
Now, things start to shift a bit from Sunday 2 August. On Sunday afternoon, we get a glassy calm with a 1ft swell, but it’s a 14-second period from the ESE, and the combined energy climbs to 86 (still weak). It’s surfable but very ordinary – not worth paddlin’ out for unless you’re desperate.
The first real standout, and I mean the *only* one worth gettin’ excited about, arrives on Monday 3 August. Ikei Island gets a jump to 4ft in the morning and 4ft in the afternoon, both from the East with a *very long period* of 15 to 16 seconds. That’s proper groundswell. The combined energy hits 556 (moderate energy) and then 741 (moderate energy). Winds are light from the north, keepin’ it cross-shore to cross-onshore, which is okay for a reef break – not glassy, but manageable. Remember, that long period makes it better for a reef like Ikei, but at a beach break it might break a bit too straight. The size is solid for intermediate surfers – 4ft is a fun wave. Crowds are listed as “sometimes,” so you might have some company, but nothin’ crazy. This is the pick of the whole window. The swell direction from the East matches the optimum direction from the guidance (NE is close enough – East is in the mix).
The swell builds even more as the week goes on, but the quality drops off quick. By Tuesday 4 August, we’re lookin’ at 5ft to 6ft from the East with 17-18 second periods, combined energy now 1530 and 1970 (strong energy) – but the wind picks up to a moderate cross-shore from the NNW, makin’ it messy. Wednesday 5 August hits 8ft from the East, 18-second period, energy soaring to 3213 and 4898 (very strong energy) – but it’s cross-onshore from the NE, choppy, and with risk of t-storms. That’s too big and messy for most, only for experts, and honestly, the wind kills it. Thursday 6 August drops back to 5ft, still messy, and then Friday 7 August gets strong cross-offshore winds from the WNW at 22 mph, but the swell is only 2ft – clean but tiny. That setup with decent swell and strong cross-off wind could actually be more interestin’ for kite surfing than paddle surfing.
After that, the weekend of 8-9 August brings clean conditions but tiny swell again – 2ft, combined energy 79-92 (weak). Then come Monday 10 August through Wednesday 12 August, we see a return of 6ft to 8ft swell from the East, but the period drops to 7-10 seconds (short period, choppy windswell), and winds are onshore or cross-onshore from the ENE, with risk of t-storms. Combined energy gets back up to 1521 (strong energy) at one point – but the quality is poor. These are not the waves you want.
So, bottom line: the best day by far is Monday 3 August. Get there for the morning session with that 4ft, 15-second East groundswell. Tuesday 4 August morning could be a second look if you’re after bigger size (5ft, 17-second period), but it’s wind-affected. The rest of the window is either flat, too messy, or too big and blown out.
Signin’ off, 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.
