Ikumi Beach Surf Forecast and Surf Report

G’day, Rusty here, and I gotta be straight with you — this outlook for Ikumi Beach is a real rollercoaster, and not the good kind. We’re looking at a 16-day window that starts with a few marginal, small-wave windows, then gets blown out by a massive, dangerous swell. There’s a long stretch of poor conditions in the middle, and the only real glimmer of hope is a brief, glassy morning more than a week out. Let’s break it down.

We kick off on Wednesday, the 26th of August. The morning offers a 6.6 ft swell from the south, with a period of 11 seconds — that’s a solid groundswell, but the wind is a light cross-shore, creating a crossing chop. The combined energy is moderate, at 1044. It’s surfable, but the tide or something else is making it marginal. The afternoon gets worse with a 4.9 ft south swell and a stronger 12 mph cross-shore wind, chopping it up.

Thursday the 27th is a step up. The morning sees a 4.6 ft swell from the south-southwest, with a 10-second period. The wind is a gentle cross-offshore breeze, and the water is clean. The combined energy is moderate (741). This is the first real window for a few tidy waves, but it’s still nothing special. The afternoon drops to 3.9 ft and is clean, but the energy fades.

Friday the 28th and Saturday the 29th are small. Friday morning has a 3.0 ft south-southwest swell with a short 8-second period, and light cross-offshore winds. The energy is weak (220). Saturday morning is the standout for this early period: glassy conditions with a 3.0 ft south swell, 8-second period, and a dead calm wind. The combined energy is only 111, so it’s tiny, but it’s *glassy* — perfect for a longboard or a beginner session if you just want to feel the glide. The water temperature is about average for the time of year, so no wetsuit drama.

Sunday the 30th is a total write-off. The morning swell drops to 2.6 ft from the south-southwest, period a pathetic 6 seconds, and the energy is a weak 72. It’s glassy, but there’s almost nothing to ride.

Then we hit a wall. From Monday the 31st of August through to Wednesday the 10th of September, it’s mostly poor to dangerous. Monday the 31st has onshore winds and a 3.0 ft swell — not worth it. Tuesday the 1st of September is a disaster: a 7.9 ft swell from the south-southeast with a 12-second period, but a 16 mph onshore wind from the east makes it a messy, blown-out mess. The energy shoots up to 1746, but it’s all for nothing. Wednesday the 2nd through Thursday the 3rd of September sees swells of 11.5 ft to 13.1 ft from the south, with periods of 12-14 seconds, and fresh cross-onshore winds of 19-22 mph. The combined energy is massive — 8966 on the 2nd afternoon — but it’s a wild, lumpy, dangerous mess. This is strictly for the experts only, and even then, the wind is so bad it’s barely surfable. At this size, it’s more interesting for kite surfing than paddle surfing.

Friday the 4th of September offers a 8.2 ft south-southeast swell with a 10-second period and a moderate cross-shore wind, but it’s still marginal. The afternoon drops to 9.8 ft from the south with a 11-second period and a light cross-shore wind, but it’s still too big for most.

Now, here’s the one true standout in the whole outlook. Saturday the 5th of September morning. The swell drops to 5.9 ft from the south, with an 8-second period, and the wind is dead calm — glassy conditions. The combined energy is moderate (467). This is the best on offer by a long shot. The break is Ikumi Beach, and it’s an exposed beach break, so it handles the south swell well. The optimum swell direction is east-southeast, and the swell is coming from the south, so it’s not a perfect match, but the glassy wind and manageable size make it the only session you’d want to paddle out for. It’s inconsistent here, so don’t expect a wave every minute, but when they come, they’ll be clean. Crowds are often around, so expect company.

Sunday the 6th of September and beyond is a write-off again. The swell drops to 3.9 ft, but the wind is onshore, and the period is short. By Monday the 7th of September, we’re back to 13.1 ft from the southeast
