The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Ikei Island over the next couple of weeks.
Honestly, I gotta be straight with you – it’s a tough run. We’re looking at a long stretch with nothing worth paddling out for. The first proper chance of a wave doesn’t roll in until Wednesday the 12th of August, and even then, it’s small. The best of what little we get is around that mid-week period, but nobody’s calling it a standout. The whole window is plagued by poor conditions, so keep the expectations low.
We start off Monday the 10th and Tuesday the 11th with a complete write-off. There’s some chest-high energy from the east, around 4 ft, and the swell’s got moderate energy (607) but it’s all blown out by strong cross-onshore winds and a choppy mess. Not a single wave worth your time.
Then on Wednesday the 12th of August, things calm down a touch. We get a 2 ft easterly swell with a period of 11 seconds, and for the first time we see some offshore winds from the WSW. The combined energy is weak (108), but it’s clean. It’s surfable, but very ordinary – just knee-to-waist high dribblers. This is the best we’ve got, but it’s barely a ripple.
Thursday the 13th of August morning is actually glassy – dead calm – but the swell drops to just 2 ft and the energy is almost nothing (98). It’s clean, but tiny. By the afternoon it’s even smaller at 2 ft.
From Friday the 14th right through to the 25th of August, it’s a brutal dry spell. We’re talking days of waves under 2 ft, weak energy, and a constant battle with onshore and cross-onshore winds that just ruin anything that tries to form. There’s a pulse of windswell on Friday the 21st of August – 7 ft from the southeast with a short, messy period of 8 seconds and moderate energy (620) – but the wind is howling cross-shore at 19 mph. That’s not surf; that’s a washing machine. For a spot like Ikei Island, a reef break exposed to the northeast, that combo is going to be ugly.
With the swell direction being mostly east to southeast and the optimum direction being northeast, nothing lines up right. The water temp is a touch warmer than normal at 86°, but that’s no comfort when there’s no surf.
Bottom line: don’t bother waxing up for a while. The only time you might get wet is on Wednesday the 12th or Thursday the 13th, and even then, bring a longboard and low expectations. The rest is a solid two-week gap of nothing.
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.
