The Lowdown

G’day, Rusty here. Look, I’ve been staring at the charts for your neck of the woods, and I’ve got to be straight with you—this 16-day window is a tough one. We’re looking at a real dry spell, with a massive gap in any decent surf. The first week is a write-off thanks to nasty winds and huge, messy swell, and then we drop into a flat or near-flat pattern for days. Let’s break it down.

The outlook starts with a bang, but not the good kind. On Wednesday, August 5th afternoon, we’ve got 8ft of east swell coming in at a long 17 seconds, but it’s a cross-onshore mess with 16 mph winds. The wave energy is pumping (4330), but it’s all for nothing—poor conditions. Thursday stays grim, with that swell jumping to 13ft and then 16ft, but the wind is fresh to strong and cross-shore, making it a lumpy, choppy disaster. By Friday, August 7th, it’s full-on storm force with 56 mph winds and 20ft swell. The wave energy is through the roof (35,239 in the morning), but this is for experts only, and even then, it’s a complete mess. Saturday, August 8th, sees hurricane-force winds of 87 mph—stay home, mate.

After that, the swell drops off a cliff. From Sunday, August 9th, right through to Tuesday, August 12th, the waves are tiny, under 3ft, with weak energy (as low as 63). The winds finally ease up and go cross-offshore, giving clean conditions, but there’s just no power. It’s a long, flat gap. Then from Wednesday, August 13th, we get a few days of survival waves—1ft to 2ft—with clean conditions, but it’s barely surfable. The energy is pathetic, often under 100. The only bright spot is a tiny uptick on Monday, August 18th, when we see 3ft of short-period east-northeast swell (6 seconds) with moderate energy (107), but it’s cross-onshore and choppy again. Not great.

Now, the one spot we’ve got is Ikei Island (reef break). It’s fairly consistent, but this forecast is a mess. The water temp is 87°F, which is a touch warmer than normal for this time of year—not a huge deal, but you’ll notice it.

The standout, if you can call it that, is the window around Thursday, August 13th through Sunday, August 16th. The swell is tiny (1ft to 2ft), but the wind goes light offshore or glassy at times, especially on the afternoon of the 16th when it’s glassy. The wave energy is weak (33 to 73), so you’re on a longboard or a foamie, but it’s clean. For a desperate surfer, the Sunday, August 16th afternoon has gentle offshore winds and clean 1ft east-northeast swell—it’s about as good as it gets in this run. The problem is, it’s an inconsistent reef break, and with these tiny waves, it’s a gamble.

Honestly, the first week is a write-off, and the second week is for the dedicated only. The best advice? Wait for a better forecast.

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.
