Alright folks, Rusty here. Let's break down the next couple of weeks for Ikei Island.
Got to be honest, it's a lean start. From July 13th all the way through the 22nd, the swell is tiny. We're looking at waves just 1ft to 1ft, coming from the east with weak energy (16-33), and the word on the water is "poor surf conditions." That's a tough stretch for a spot that's usually fairly consistent. The winds are actually decent for a lot of that time, with some clean offshore breezes from the SW and even a glassy morning on the 23rd, but there's just no push. The water is sitting at 82°, which is a bit cooler than normal for this time of year, but it won't matter when you're just sitting there.
Things perk up a little around the 23rd of July. The swell bumps up to around 2ft to 2ft, with energy in the 80-96 range. The wind is mostly light onshore or cross-onshore from the east, so it's not perfect, but it's rideable. Still, the wave comment stays "poor surf conditions," so it's not a green light.
The only real pulse of energy comes right at the end. On Monday, July 27th, we see a 5ft swell from the SE with a 11-second period. That's a groundswell, and the energy hits 582 – that's solid. That's the best of the whole forecast. The kicker is the wind, which is onshore from the ENE at 9-12 mph, so the surface won't be glassy. At that size, with a longer period, it's strictly for the experts on a reef break. The wind is a concern, but it’s the only time we get any real power.
For the first week and a half, you're better off doing something else. The 27th of July is the one to watch, but it's a long way off, so don't book your flights yet. It's a quiet stretch for a spot that's usually more reliable.

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.
