The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Ikei Island over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a grim stretch. We’re looking at a solid 9-day blank run right from the start with absolutely nothing worth paddling out for. The first whisper of anything surfable doesn’t show up until Saturday the 15th of August, and even then, it’s barely a whisper.

The water temps are sitting at 87°F which is a touch warmer than normal for this time of year, so you’ll be sweating in the lineup, not that you’ll be in it much.

Here’s the rundown. The first real glimmer of hope comes Saturday morning, August 15th. We’ve got a tiny 2ft swell pushing in from the ENE, with a period of 11 seconds. The combined energy is a weak 120, so don’t expect any punch. The wind is a gentle breeze from the WNW, giving us a cross-offshore flow and clean conditions. The report says “surfable waves but very ordinary conditions,” and I’m inclined to agree. It’s not good, but it’s the only thing on the horizon that’s not a total write-off. For a beginner, this is about as small and gentle as it gets, but for anyone else, it’s a frustratingly small window.

After that, it’s more of the same small, messy junk until about Thursday the 20th of August. On Thursday morning, we see a little bump to 4ft from the E with a 9-second period and 280 combined energy. The wind is onshore from the east, so it’s going to be a lumpy, frustrating paddle. This is still a “poor surf conditions” call, and it’s a short-period windswell, so it’s going to be fat and weak. Not your friend.

The whole period is dominated by these small, inconsistent ENE swells and a lot of wind that’s either cross or cross-on. The standouts are non-existent. The best on offer is the Saturday morning of the 15th, but that’s a low bar. If you’re desperate for a splash, that’s your window. Otherwise, I’d leave the boards in the car and go find something else to do.

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.
