Ikumi Beach Surf Forecast and Surf Report

Alright, let’s break it down, crew. We’re surfing Ikumi Beach, and right now, it’s a bit of a slow starter. The water’s sitting at 84°, which is a touch warmer than normal for this time of year—nothing extreme, but you’ll notice it’s a little extra balmy.

First up, Monday the 31st of August is a write-off. Tiny 2-foot swell from the south, weak energy (86), and a cross-shore breeze making things choppy—leave the board in the shed.

Tuesday the 1st of September dawns with glassy conditions and a slight air, swell dropping to 1 feet from the ESE, period 13s—so it’s clean but tiny. Energy is weak (114). It’s surfable if you’re desperate, but nothing to get excited about. The afternoon goes cross-onshore and choppy, so forget it.

Wednesday the 2nd sees a bit more size—4 feet from the SSE, period 8s—but it’s short-period stuff with cross-onshore wind and a risk of thunderstorms. Energy is moderate (267), but conditions are marginal at best.

Thursday the 3rd is where things perk up. Morning brings 4 feet from the SSE, period 8s, but the wind is light cross-offshore and the sky is clean. Energy is moderate (241) and the forecast says “expect good surf conditions.” This is the first decent window—small but clean, good for a paddle.

Into the weekend, Friday the 4th jumps to 6 feet from the south, period 9s, energy jumping to 618 (moderate), but heavy rain and a moderate cross-shore breeze make it messy. Not worth it.

Saturday the 5th drops back to 3 feet from the ESE, and the wind is cross-shore again—poor conditions across the board.

Sunday the 6th builds back to 6 feet from the ESE, period 10s, energy 859 (moderate), but it’s cross-onshore and choppy. By the afternoon, the swell hits 10 feet from the east, energy 2797 (strong), but the comment says it’s too big for this break—so that’s a pass unless you’re packing a tow-in setup.

Now, Monday the 7th of September is the standout. Morning is glassy, calm wind, 7 feet from the ESE, period 11s, energy 1181 (strong). The forecast says “excellent surf conditions for experienced surfers.” That’s a solid call—clean, powerful, and that longer period is giving it some shape. The afternoon holds up with 7 feet, glassy, and energy 1009. This is your best bet in the whole run.

Tuesday the 8th drops off to 3 feet, and the rest of the week is a mix of marginal and poor. Wednesday the 9th afternoon sees 8 feet from the SE, period 10s, but it’s cross-onshore and choppy—not good.

Thursday the 10th blows up to 13 feet from the SE, period 13s, energy 5037 (very strong)—but it’s way too big for Ikumi, and the wind is messy. Save it for the big-wave chargers.

The following week, from the 11th to the 15th, is mostly stormy, with onshore winds, thunderstorms, and big but messy swell. The 13th and 14th see 8 to 10 feet from the SE, but with onshore wind and stormy conditions—not worth paddling out.

So, to wrap it up: the best surf is Monday the 7th of September, with clean, glassy conditions and solid 7–7 foot ESE swell. That’s your window. Everything else is either too small, too messy, or too big for this spot.

Stay salty,
