The Lowdown
Alright, Rusty here again. Let's talk surf.
It's a flat start for Ikei Island. Through the end of July and into early August, we're looking at tiny, weak swell – maybe 1 to 2 ft – with combined wave energy barely hitting 50. Winds are mostly side or side-onshore, and the report says "poor surf conditions." You'd be better off doing something else. There's a solid stretch of nearly two weeks where the waves just aren't worth the paddle.
Things perk up around the 2nd of August. The swell period jumps to 16-17 seconds, and the energy climbs, but the height is still small at around 1 to 2 ft. Those are long-period pulses, but still tiny. Winds stay light and side-shore, so it might look pretty but isn't offering much.
The real standout window is from Monday the 3rd of August through Wednesday the 5th of August. There's a proper pulse of long-period groundswell from the east. Monday sees swell build to 4 to 4 ft, with combined energy jumping into the moderate range, over 600. Winds are light from the NNE, so it's side-onshore but very light – just small bumps. The period is a very long 16 seconds. For a reef setup like Ikei, that long-period energy between sets can make paddling out a little easier.
By Tuesday the 4th, it kicks up another notch – 6 ft east swell with a 17-second period and combined energy over 1500. That's strong wave energy. The wind stays light with that NNE flow in the morning. At 6 ft, it's pushing into intermediate territory, and the power behind those sets will be serious. Not for beginners. The light wind means the surface should be workable.
Then Wednesday the 5th of August is the pick. A 5 ft east swell, still with that 16-second period and combined energy around 1162. The key difference? The wind swings light from the south, giving us a side-offshore flow. That means clean, groomed faces. The report flags it as excellent surf conditions for experienced surfers. South winds, light, with a solid east groundswell wrapping into this exposed reef. Since it's fairly consistent and the swell direction matches the optimum northeast direction for Ikei, we are in business. Crowds can be a thing here sometimes, so be ready to share. The water temp should be about average for this time of year, nothing too unusual.
After that, the swell eases into the weekend, dropping to 3 ft and below through the 6th and 7th of August, losing that long-period energy. The winds stay offshore from the south, so it will be clean, but the power fades. That Wednesday morning is the session to aim for.

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.
