Ikumi Beach Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s shaping up at Ikumi Beach over the next couple of weeks. Honestly, the first week is a bit of a struggle, but there’s a real standout window at the end if you’ve got some experience.

The surf kicks off small and clean on Friday the 21st. Morning’s the go – glassy conditions with a light ESE breeze, and a 3-ft S swell pushing in at 9 seconds. Wave energy is weak (175). It’s surfable but nothing to write home about. Afternoon turns messy with a cross-shore SSW wind and the threat of a storm, so don’t bother.

Saturday the 22nd and Sunday the 23rd are much the same story: tiny 2- to 2.5-ft SSW swells, glassy mornings that go to junk in the afternoons. The combined energy stays under 155, so you’re barely getting a ride.

Monday the 24th sees a big jump in swell height – 6 ft in the morning, 8 ft by the afternoon – and the period stretches to 16–17 seconds, a proper groundswell. Wave energy rockets up (2,629 to 4,151), but it’s onshore wind and the tide seems off. It’s a marginal call; maybe a few clean ones if the wind swings right, but I wouldn’t get too excited.

Tuesday the 25th is a monster. We’re looking at 15-ft SSE groundswell with a 16-second period and massive energy (10,234 to 10,651). That’s expert-only territory. The cross-on wind is light, but the swell is just way too big for Ikumi. Kite surfers might love it, but for paddle surfing, this is a stay-on-the-beach day.

Wednesday the 26th and Thursday the 27th are a write-off: storm-force winds (up to 31–34 mph) from the ESE and SW, with 10-ft messy swell. Thursday afternoon cleans up a bit with cross-offshore wind, but the swell is still 8 ft and the energy is high (1,104). It’s more of a novelty for the brave.

Friday the 28th brings a breath of fresh air. The morning is glassy, light ENE breeze, and a 4.5-ft SSE swell at 9 seconds. Energy is moderate (355), and the conditions are clean. It’s small but fun – good for a longboard or a fish.

Now, here’s the highlight. September 1st (Tuesday) is the real deal. Morning and afternoon both glassy, with a 7–7.5-ft SE groundswell, 14-second period, and strong wave energy (1,922 to 2,238). This is excellent for experienced surfers – powerful, lined-up waves with no wind to mess them up. The swell direction (SE) is spot on for the break’s optimum (ESE). This is the standout session of the whole outlook. Don’t miss it if you’ve got the skills.

After that, things get big again. September 2nd brings 8–10-ft SE swell with rising energy, but by the 3rd we’re looking at 16–20-ft SE groundswell with 18-second periods and energy over 20,000. That’s an absolute bomb – only for experts, and even then, Ikumi might be too exposed. Kite surfers will be out in force.

The water temperature is about average for the time of year here, nothing unusual.

So, bottom line: the first week’s a slow burn with a couple of small glassy windows. The real prize is Tuesday, September 1st – clean, head-high plus, and glassy. After that, it’s either too big or too windy until the swell fades again.

Stay keen.
