The Lowdown
Alright, let’s break this down. This is for Ikei Island, a reef setup that needs swell from the NE to really fire. The first week and a half is a write-off for any proper surfing, but the back half of the outlook has some serious promise.
Right now through the end of July and into the first few days of August, the ocean's flat. We’re looking at tiny 0.7 ft to 1 ft waves with weak energy, mostly from the SE and ESE – completely the wrong direction for this break. The combined swell energy is barely ticking over, mostly in the teens and thirties (34 to 49), just pathetic. Winds are light, sometimes glassy, which would be nice if there was any wave to ride, but there isn't. It's a dead period.
That changes on the 3rd of August. A pulse of long-period groundswell from the E starts to build, pushed by a 15-second period. On Monday morning the 3rd, we’ve got 3 ft swell with energy jumping to 291, and by the afternoon it’s 3 ft at 417 energy. But the winds are onshore and cross-onshore, and the conditions are only marginal. Still not worth paddling out.
The 4th of August sees the swell bump up significantly: 5 ft to 5 ft from the E with a 16-second period. The combined energy rockets into four digits (1020 to 1215), so there’s proper power now. But it’s still got cross-shore winds and the forecast flags it as marginal due to tide or wind issues. Close, but not quite.
Now here’s where it gets real. The 5th of August, Wednesday morning, is a standout. We’ve got 6 ft of clean, long-period E swell (17 seconds) and glassy conditions. The energy is over 2107 – that’s strong. Winds are glass, the water temp is about 85°, which is a touch warmer than average for the time of year. That’s a true window for experienced surfers. This is the best wave of the forecast. That afternoon it holds, though wind shifts to cross.
The swell keeps pumping. On the 6th of August, Thursday afternoon turns glassy again with 7 ft of E swell at 17 seconds and energy hitting 2879. Beautiful, clean surf for those who know what they’re doing.
Then the 7th of August, Friday – Friday afternoon is exceptional. 10 ft of E swell at 17 seconds, glassy conditions, and combined energy over 5000. This is big, powerful, and clean. It’s for experts only, no question. The biggest call of the whole run.
Saturday the 8th of August is the absolute peak. Morning has 13 ft at 18 seconds from the E, with glassy conditions and energy a monstrous 10670. The afternoon is still 13 ft from the ENE, glassy, energy 9368. This is not for the faint of heart – expert level only, and absolutely world-class if it lines up right at Ikei Island. This is the one to circle on the calendar.
After that, the swell drops fast. The 9th of August still has size but with onshore winds and dropping energy. By the 10th and 11th, it’s fading into the 4 ft to 6 ft range with cross-onshore winds and poor quality. The run is over.
So here’s the bottom line: forget the first week. From the 5th of August through the 8th of August, Ikei Island has the potential to be absolutely pumping. The 5th morning is your first standout for experienced surfers, the 7th afternoon is for the brave, and the 8th is the crown jewel – but it’s a beast. If you’re not an expert, stay on the beach and watch.

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.
