The Lowdown

Alright, let me level with you. The surf outlook for the Ikei Island area over the next 16 days is a pretty bleak stretch, but I'll break it down for you as honest as I can.

We start off on Thursday, September 3rd with a bit of swell – around 8 ft from the east, with the combined energy of all swells directed here at a hefty 1578, so there's plenty of juice. But it's messy. Morning has a risk of thunderstorms with a cross-on shore wind blowing at 12 mph, making it choppy and tough. The afternoon cleans up a bit with a cross-off wind from the west-northwest at 16 mph, but it's still marginal. That 8 ft is pushing into the "too big for beginners" territory, so only intermediate and above should even look.

Friday morning, September 4th, drops right off to just 3 ft from the east, period around 9 seconds, and the energy is down to 142. The wind is offshore from the southwest at 16 mph, which is clean, but it's just ordinary, small waves. By afternoon it's even smaller at 2 ft and a weak 8-second period, energy down to 82, so really not worth paddling out unless you're desperate for a splash.

We then hit a long, dry spell. From Friday afternoon all the way through to Monday, September 14th, there's basically nothing worth talking about. The swell stays small, mostly under 3 ft, and when there is a tiny bump, the wind is cross or onshore, or there's a risk of storms. The conditions are consistently poor, and the scores reflect that – just a sea of zeros. It's a real bummer for the area.

A glimmer appears on Tuesday morning, September 15th. Swell picks up to 4 ft from the east, with a period of 10 seconds, giving us a moderate energy reading of 332. The wind is a light cross-shore from the south-southeast, so it's not perfect, but it's the most promising we've seen in a while. It's still only a marginal call, tide dependent, but if you're keen, this is the one to target. By afternoon it jumps to 5 ft, but the wind goes onshore, so that's no good.

The last few days from September 16th to 18th see the swell fade again, with some clean conditions under offshore winds, but the wave heights are tiny – 2 ft to 3 ft. Even the cleanest conditions can't make a knee-high wave exciting.

Water temperature is 84°F, which is about average for this time of year, so you won't need a thick suit, just some wax.

If you're looking for the standout, it's got to be Tuesday morning September 15th. It's not world-class, but it's the only proper window where you've got a decent sized swell, a reasonable period, and a wind that's not ruining it. Just don't expect perfection.

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.
