The Lowdown

Alright folks, let’s get into it. I’m looking at the Ikei Island (Ikei-Island) picture for the next couple of weeks, and honestly, it’s a tough stretch. The first week is pretty much a write-off, with a heap of stormy wind and messy swell. There’s a brief window of hope around the 2nd and 3rd of September, but it’s got serious caveats. After that, it’s back to the grinder.

The water temp is close to average for this time of year, so no dramas there.

For the first several days, from Wednesday the 26th of August right through to the end of the month, it’s a no-go. We’ve got a mix of risk t-storms, strong cross-off and cross-on winds, and the swell is either small, short-period, or coming from the wrong direction. The combined energy is weak to moderate (e.g., 746, 448, 107), and the wave comments are all “poor surf conditions.” This is a long stretch of flatness and blown-out junk.

The 31st of August and 1st of September see a rise in swell size, but the wind is howling from the NE and NNW, cross-on and cross, making a mess of things. The combined energy jumps up to 941 and then a massive 3124, but the wave comment is still “poor surf conditions.” It’s just too wild.

Now, the 2nd of September (Wednesday) morning is the one standout. We’ve got a solid 25 ft swell from the NNW with a period of 11 seconds, and the wind is WNW at 25 mph, which is cross-off, keeping things clean. The combined energy is a massive 13,915. But here’s the big caveat: the file says the swell is predicted to be too big for this break. This is a proper, heavy, expert-only situation. The afternoon of the 2nd drops to 13 ft (N, 13s) with cross-off wind, but it’s rated as marginal. A surfer looking for a big, clean, dangerous wave could have a look on the morning of the 2nd, but you need to know what you’re doing.

The 3rd of September (Thursday) morning is small and rubbish, but the afternoon brings an 12 ft swell from the NNW (13s) with a moderate cross-shore wind. The combined energy is 3703, but it’s rated as marginal.

The 4th and 5th of September are a mix of onshore and cross-on wind with swells around 6 ft to 8 ft, but the quality is poor. After that, from the 6th of September onward, it’s a slow fade into strong onshore winds and diminishing swell, with the 8th and 9th of September seeing severe gale force winds and completely blown-out conditions. The 10th of September is the last call, with a tiny 2 ft swell and a near gale, but it’s clean. Not worth paddling out for.

So, to sum it up: the first week is a total dud. The 2nd of September morning is the only real standout, but it’s for experienced big-wave chargers only. The 3rd of September afternoon is a marginal option. The rest of the period is a write-off. If you’re a beginner, stay at home. If you’re an expert with a big board and a big heart, the 2nd of September morning could be a memory.

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.
