The Lowdown
Alright, surfers, Rusty here. Let's be straight with you: this stretch of the forecast is a real heartbreaker. We’re looking at a solid run of days where the ocean just doesn’t want to play ball. The swell is small, the winds are messy, and even the standout windows are marginal at best. Don’t go booking a surf trip around this.
The pick of a very average bunch is Ikei Island (Hawaii), a reef setup that’s fairly consistent, but it’s going to be tested. The first week is basically a write-off. We’ve got gale-force winds and storm threats through Saturday and Sunday, with waves only around 3 ft to 3 ft. The energy is weak, sitting at 157 on Saturday morning and dropping from there. Not worth paddling out with those conditions.
Monday the 10th sees the swell bump up slightly to 3 ft, with a better period of 14 seconds, but the wind is fresh and cross-shore, making things lumpy. The wave energy is moderate at 361, but the quality is poor. Tuesday and Wednesday settle the wind down a bit, but the swell drops back under 3 ft. It’s clean-ish, but tiny.
Now, here’s the only glimmer of hope. On Saturday the 15th, the late afternoon session might just be surfable. The swell picks up to 3 ft from the ENE with an 11-second period. The wind will be light, with a slight air, and even though it’s technically cross-on, it could glass off enough to make Ikei Island’s reef worthwhile. The energy is moderate at 205. It’s a marginal call, but if you’re desperate, that's your window. The water temp is about average for this time of year, so no surprises there.
After that, we slide back into the doldrums. The wind turns onshore and the swell just doesn’t have any push. A 4 ft bump on Tuesday the 18th is short-period and junky. The following week is just more of the same – small, wind-affected, and uninspiring. There’s a small spike to 4 ft on Friday the 21st but with onshore winds and short-period swell, it’s going to be a mess.
For the rare spot that’s this inconsistent, this kind of blank run is more normal than not. It’s frustrating, but it happens. I’d be looking at other hobbies for the next couple of weeks.
Stay salty.

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.
