The Lowdown

Alright, Rusty here. Let’s break down what’s on the cards for Ikei Island over the next couple of weeks.

Straight up, we’ve got a bit of a wait on our hands. The short-term is a write-off, so don’t bother paddling out just yet. It’s not until Wednesday the 2nd of September that we even see a hint of a chance, and even then it’s marginal. The big news is really sitting way out at the end of the forecast period, on the 8th and 9th of September.

First, the grim stuff. From now through the rest of August and into early September, it’s a wall of poor conditions. We’re talking strong winds, cross-shore mess, and lumpy chop, with the added headache of storm risks. The waves are there – in fact, on Tuesday the 25th of August we’ve got a solid 16 ft easterly swell with immense energy (14257) – but a screaming 19 mph north wind and cross-shore conditions make it a total mess. That’s kite-surfing territory, not paddle-surfing. That big swell hangs around for a couple days with similar wind issues. By the 27th, the swell drops to nothing.

We then go through a long stretch with no real surf recommendations, nothing worth paddling for, right through until Wednesday the 2nd of September. That morning, things start to look a little better. We get a 5 ft easterly swell (11-second period) with a cross-offshore wind from the WNW at 12 mph. The water temperature here is 84°F, which is bang on average for this time of year. The surf is clean, but it’s only a marginal, small wave option – a 2/10 sort of session.

After that, it’s back to poor surf and small, weak energy until we hit the real standout window. The best on offer is Tuesday the 8th of September. The morning session at Ikei Island looks proper. We’ve got a 7 ft swell from the ESE with an 8-second period, and more importantly, a light 6 mph cross-offshore breeze from the NW. That means clean, peeling waves. The combined swell energy is a solid 636, so there’s some push behind it. This is a reef break that’s fairly consistent and exposed to the swell, so it should handle the size well. The following morning, Wednesday the 9th of September, also looks promising with a bigger 8 ft ESE swell (9-second period) and a light 6 mph cross-shore breeze, though it gets a little bigger in the afternoon up to 10 ft. For that sort of size, over 8 ft, you really need to be an expert. The sets will have some punch to them.

Honestly, for the first week, just sit it out. The real action is that Tuesday and Wednesday stand out at the start of the second week. The long-range call is promising, but we all know forecasts can wobble. Keep an eye on it.

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.
