The Lowdown
Alright, let’s keep it real, folks. For the next couple of weeks, Ikei Island (Okinawa) is flat out quiet. There’s a long stretch of tiny surf ahead, so don’t expect to get wet with any proper waves. It’s a bit of a dry run for this spot, but that’s just how it goes sometimes.
Starting on Tuesday the 14th of July, we’ve got a tiny 1-foot easterly swell with weak energy. Wind is a cross-off from the south at 9 mph, so it’s clean enough for a log, but the call is poor surf. Water temp is 82°, a bit cooler than average for this time of year.
Wednesday morning the 15th brings a nice offshore from the WSW at 9 mph, keeping the surface glassy. But the swell is still a weak 1-foot, 10-second period, with next to no energy. Still poor. This same story holds all week and into the next – a consistent offshore or cross-off breeze keeps the water looking clean, but we’re stuck on that 1-foot range from the 15th all the way through the 24th of July.
There’s a tiny moment on Saturday the 25th of July morning where it gets interesting. The wind goes glassy – dead calm at 3 mph from the SSE. The swell bumps to 1 feet, with energy at 36. Still poor surf, but if you’re on a longboard or a funboard, that glassy morning is your best shot for some knee-high blips. It’s the standout, only because everything else is flat.
The last few days of the month see a bit more push. On Monday the 27th of July morning, the swell goes east with a longer 13-second period, energy hits 55, but it’s a cross-shore wind from the north at 16 mph kicking up chop. That’s not surfable. By Wednesday the 29th, the swell gets to 2 feet on a 14-second period from the east, with combined energy at 207 (moderate). But the wind is cross-onshore from the southeast at 9 mph, making it choppy. With that wind and a long-period swell, this reef setup starts looking more like a kite spot than a paddle spot.
So here’s the bottom line: there’s no real “best day.” The standout is that glassy Saturday morning on the 25th for the tiniest of longboard sessions. Everything else is a waiting game. Forecasts can change, but right now, we’re stuck in a flat spell.

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.
