The Lowdown

Alright, Rusty here. Let’s break down what’s coming for Ikei Island. This is a reef setup that catches swell, and it breaks fairly consistently, but don’t hold your breath – we’ve got a long, quiet stretch to get through first.

Right now, nothing’s happening. From Tuesday, August 18th, all the way through Monday, August 24th, it’s either flat or chopped to bits. There’s a little bump around the 20th, with waves around 6ft from the southeast, but fresh cross-onshore winds and storm clouds make it a total mess. Water temp is about 84°F, which is normal for this time of year. Honestly, don’t bother.

Then things change. After a weak spell on the 23rd, the surf starts building Monday the 24th. That afternoon brings a 6ft southeast groundswell with a very long 17-second period. The energy is pumping strong. The wind is onshore, so not perfect, but it’s getting interesting. Wednesday the 26th sees the swell hit 13ft from the ESE with a 16-second period, and the energy is massive. The wind is cross-onshore from the northeast – a bit of a buzzkill. This is for experts only – way too big for beginners.

Now, the real standout is Thursday, August 27th. Morning brings a 16ft easterly groundswell with a 15-second period, and the energy is enormous. The wind is a gentle cross-shore from the north – that’s clean glassy conditions. The swell direction is east, which is exactly what this break likes. This is the day. It’s huge, powerful, and for experienced surfers only. Crowds can show up here sometimes, but at this size, it might be quieter. By the afternoon, it’s 18ft with a cross-shore breeze – still good, but massive.

Friday the 28th is still big but dropping. A 20ft swell in the morning with a clean cross-offshore wind from the west-northwest. The energy is still huge, but the period is shorter at 12 seconds. By the afternoon, it’s down to 12ft. Still a big wave, but more manageable.

After that, it all fades. From Saturday, August 29th, through to Wednesday, September 2nd, it’s back to tiny, weak, and windy. A few knee-high bumps with fresh onshore winds. Not worth a second look.

So, to sum it up: the first week is a total blank. The real action hits from the 24th to the 28th, with Thursday the 27th being the clear winner – huge, clean, and powerful. That’s the one to mark on your calendar. Everything after that goes flat. Stay safe out there.

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.
