Alright, let’s see what’s in store for Ikei Island over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a frustrating outlook for Ikei Island. The start of the period is a total write-off. We’re looking at a massive, dangerous swell coming in from the southeast, with wave heights climbing from 15 ft up to a monstrous 28 ft. That’s not surf, that’s a washing machine. The wind is howling onshore from the east at 22 to 37 mph, and the risk of thunderstorms is constant. The combined wave energy is just insane, hitting values like 9,709 (moderate) and then 44,945 (very strong), so it’s got plenty of punch, but it’s all wrong. For a reef break like Ikei Island, that’s a no-go. This window is purely for the big-wave specialists with a death wish, or maybe the kite surfers if they’re feeling brave. Conditions don’t settle down until the 14th of July, which is a solid five-day gap of nothing rideable.

From Tuesday the 14th through Thursday the 16th of July, we get a little window of clean, small surf. The wind goes light and variable, even glassy at times, with a cross-offshore flow. But the swell is tiny – we’re talking 1.0 ft to 2 ft from the east and southeast, with a period around 9 to 12 seconds. The combined energy is weak, between 16 and 50. It’s clean, but it’s barely surfable. You’d be out there on a foamie just to get wet. The water temp is sitting at 84°, which is bang on average for this time of year, so at least you won’t need a spring suit.

Then we hit another flat spell from the 17th to the 19th. The wind goes messy again, and the swell drops to nothing. It’s not until the 20th of July that we see a bit of life. A new swell from the east-northeast starts to build, hitting 6 ft to 7 ft on Monday the 20th. The period is short, around 8 to 9 seconds, so it’s a windswell, not a long-period groundswell. The combined energy ramps up to 855 (moderate), and the wind is clean and cross-offshore from the south. This is the best window of the whole forecast. The size is right on the edge of intermediate territory – a bit punchy for beginners, but manageable for anyone with a bit of experience. The direction is from the ENE, which is a bit off from the optimum NE direction for this break, but it’s still workable.

The 21st and 22nd look messy again with cross-onshore winds and choppy conditions, and the swell direction jumbles around. The last real glimmer of hope is on the 24th of July. The morning shows glassy conditions with a light wind from the southwest, and a small 3 ft swell from the north. The combined energy is a weak 88, but with the glassy surface, it’s a clean, if small, option. The break is fairly consistent, and crowds are sometimes an issue, so you might have it to yourself.

Overall, I’d say the standout is Monday the 20th of July. The swell is the biggest of the clean windows, the wind is good, and the energy is moderate. It’s not a world-class day, but it’s the best we’ve got. If you’re a beginner, steer clear of the 5 ft-plus days. If you’re an expert, you’ll be bored until the 20th. Long story short: there’s a lot of waiting for not much reward here.

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.
