G’day, Rusty here. Looking at Ikei Island over the next couple weeks – it’s a mixed bag. The reef here faces the NE, and the first few days are a slow start. But there are a couple spots in the calendar that’ll make it worth the wait.
Sunday the 5th is flat with a 1ft ESE swell, 9-second period, cross-off wind – just poor. Not worth your time. Monday the 6th afternoon shows a little life: 2ft ESE swell with a 16-second period, light cross-off breeze, combined swell energy moderate (225). It’s surfable but nothing special.
Tuesday the 7th is where we get our window. Tuesday morning brings 4ft ESE swell, 13-second period, glassy wind from the NW at 3 mph. Combined energy is strong (663). Clean and building. Tuesday afternoon is the pick: 5ft ESE swell, 16-second period, dead calm – 0 mph wind. Combined energy hits (1016). That’s excellent surf for experienced surfers – long, clean lines off the reef. Crowds can show here, so get in early.
Wednesday the 8th the swell jumps to 10ft in the morning and 12ft in the afternoon, both ESE with long 17–18 second periods. Energy is massive – (5163) and (6370). But the wind turns cross-on from NNE then NE at 6–12 mph, and at this size it’s only for experts. Thursday the 9th is huge – 15ft to 18ft SE swell, onshore wind from NE at 19–22 mph, energy through the roof (12738 to 18956). Blown out and dangerous.
From Friday the 10th through Sunday the 12th, it’s a gap of nearly three days – storms, strong winds, no real swell. Monday the 13th is still poor. Tuesday the 14th brings back size (13ft ESE, 9-second period) but it’s onshore and choppy. Wednesday the 15th is similar – 10ft to 12ft, cross-on wind, energy around (1156 to 1186). Marginal at best.
Thursday the 16th morning shows a 13ft ESE swell, 11-second period, cross-on, energy at (5864). Still onshore. The rest of the week into the 20th is messy – big but blown out.
The standout is Tuesday the 7th afternoon. That glassy, long-period ESE swell at 5ft with no wind is the best on offer. Tuesday morning is a solid backup.
Water temps are around 82°F, pretty average for this time of year.
Don’t miss that Tuesday session.

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.
