Kewalos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

We’re starting off quiet, I gotta be straight with you. The first few days are a bit of a write-off. Sunday the 30th of August through Thursday the 3rd of September – it’s all pretty average. The swell is mostly short-period windswell from the ENE, coming in around 6 ft to 7 ft, but the energy is weak to moderate (659 to 670 on the combined energy scale). The wind is a fresh cross-offshore breeze at 22 mph, so the surface is clean, but the waves just aren’t cooperating. The water temp is about average for the time of year, so nothing wild there.

Then we hit a bit of a lull on the 2nd of September Wednesday morning with a tiny 3 ft S swell, period of 16 seconds – that’s a long-period groundswell, but it’s too small to do much at Kewalos (reef). The energy is still moderate (793). It’s a tease.

The real standout, and I mean the only one worth getting excited about, is the 9th of September. Wednesday morning looks like a proper window. We’ve got a solid 10 ft swell from the ENE, period of 10 seconds, and the combined energy is strong at 2003. That’s a lot of power. The wind is a gentle cross-offshore breeze at 9 mph, which means the surface will be clean. This is for experienced surfers only – 10 ft is big, and this is an advanced reef break. The crowd profile here is "often", so expect some company if you’re keen. The swell direction is ENE, and the optimum swell direction for this spot is SSE, so it’s not a perfect match, but the size and the clean wind make it the best on offer. Wednesday afternoon the wind shifts to a light cross-onshore at 6 mph, with a bit of surface ripple, so the morning is definitely the call.

After that, things drop off again. Thursday the 10th brings a 7 ft ENE swell, but the wind turns onshore from the SSE, messing up the quality. The rest of the period into the second week is a mix of small, weak swells and poor conditions. The 14th of September Monday morning has a tiny 2 ft SW groundswell with a very long period of 20 seconds, but it’s barely surfable.

So, my advice: if you’re an experienced surfer, pencil in the morning of the 9th of September. The rest of the run is a struggle. This is a spot that can be fickle, and we’re in a bit of a dry spell. It won’t stay poor forever, but for now, patience is the name of the game.

Rusty.
