Ikumi Beach Surf Forecast and Surf Report

Alright, Rusty here, let’s get into it. The next couple of weeks are a bit of a mixed bag for Ikumi Beach. The first few days are pretty lackluster, with tiny, weak swells and less-than-ideal winds. But then, things start to ramp up big time, and by the second week, we’re looking at some serious, heavy groundswell. However, there’s a catch – that swell might just be too much for this spot.

The first real sniff of decent surf hits on Wednesday morning, 2nd of September. We’ve got a 3ft swell out of the SSE, with a period of 8 seconds. The combined energy is moderate (214), and the wind is glassy – dead calm. That’s a major positive. The water is about average for this time of year. It’s small, but it’s clean and surfable. This is your best bet for a fun, easy session for the first week. It’s a good one for the beginners, too, as the swell is well under 5ft.

Then, Friday morning, 4th of September, we see a bit more size coming in. A 3ft ESE swell, period 8 seconds, with a gentle offshore breeze making it clean. The energy is moderate (222). It’s still not huge, but a clean wave with that wind is always a good thing. It’s a solid option.

After that, be warned. The surf jumps up significantly. From Saturday, 5th of September, the swell gets bigger and bigger. Saturday morning sees a 6ft ESE swell (518 energy), and by afternoon it’s an 8ft ESE swell (1046 energy). The wind is onshore or cross-shore, so it’s going to be messy. That’s moving into expert-only territory, but the wind is a problem.

The real big stuff arrives from Sunday, 6th of September. We’re talking 10ft ESE swells, with periods of 10 seconds, and combined energy well over 1600. The wind is onshore and strong – 15 mph. This is not a paddle surfer’s friend. The waves will be big, powerful, and choppy. This setup looks far more interesting for kite surfing than paddle surfing.

The pattern continues. We get a bit of a dip on the 8th and 9th with 6ft to 5ft swells, but the wind is still cross-onshore. Then, from 11th September onwards, it’s game on for the big stuff again. A very long period groundswell arrives. On the 11th, we’re looking at a 6ft S swell with a 14-second period (1757 energy) and a strong cross-offshore wind. The period is significant – it’s a long period groundswell that will be powerful and have long lulls between sets. It’s a good sign for a point break or reef, but at a beach break like this, those long-period swells can break straight and be tricky.

Then the real giants come. Saturday, 12th September, sees a 10ft S swell with a 16-second period and a massive 6546 energy. The wind is light offshore, so it’s clean. But at 10ft, this is for experts only. Sunday, 13th September, is similar with an 12ft S swell (6578 energy) and glassy conditions. Again, massive, clean, but way too big for most. The same goes for Monday, 14th September, with a 10ft S swell (2599 energy) and glassy morning conditions. All these are wind and tide favorable, but the swell is just too big for Ikumi Beach.

So, to sum it up: the standout is Wednesday morning, 2nd September, for a clean, small session. If you’re an expert, the glassy, giant swells of the second week, like Sunday, 13th September, are a spectacle, but the break itself might not handle it. For the rest of us, it’s a week of waiting for cleaner, smaller windows.

Rusty.
