The Lowdown

Imperial Version

Alright folks, Rusty here. Let's take a hard look at what's on the table for Ikei Island over the next 16 days.

I’ve got to be straight with you – this is a long, painful wait for the good stuff. The strongest surf we see is right in the middle of the 16-day window, but it’s a real heartbreak because the conditions are just brutal. For the first full week, from the 19th of August right through to the 25th, we’re looking at a lot of chop and cross-onshore wind. The water temperature is sitting at a normal 84°F, so that’s not the issue.

The real problem is that the wind is howling out of the ESE and SE, up to 34 mph, ramming into the swell. That means the waves are going to be a lumpy, blown-out mess, even when the swell hits 16 ft on the 22nd. The combined energy is massive (4691) but the wind kills it. That setup, with the beach and reef, honestly looks more interesting for kite surfing than paddle surfing.

Then, we get a shift. The 26th of August is the standout. By Wednesday afternoon, the wind swings around to the NW at 22 mph, and it’s blowing cross-offshore. The swell is a solid 13 ft out of the E, with a long 16-second period, carrying a massive 9071 energy reading. The commentary says "clean." This is expert-level stuff, big groundswell, but if you’ve got the skills and the board, this is the window. The 27th still has clean cross-offshore wind from the WNW, and a 10 ft ENE swell (5465 energy), so there’s a second day of potential there.

After that, the energy drops. The 28th and 29th of August have some clean, offshore wind from the W and NW, with swell around 6 ft to 7 ft, but the energy is much lower, down in the 800-1000 range. It’s a nice, clean paddle for a confident surfer, but it’s nothing compared to the 26th. Then the 30th through to the 3rd of September, we’re back to small, choppy, or poor conditions. Overall, the 26th and 27th are the only ones worth planning a trip around.

Rusty out.

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.
