Keaulanas Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at your local surf outlook for the next couple of weeks. Let’s get into it.

Right off the bat, we’ve got a rough start. Monday the 31st of August is a write-off – the swell is tiny at 2ft, and the wind is a messy cross-off. Not worth paddling out for. The whole first week is a bit of a struggle, honestly. The energy is low, and the conditions are just teetering on the edge of okay without ever really nailing it.

The real standout here is Keaulanas. It’s a beach and reef setup, and it’s consistent. Crowds can pop up sometimes, but that’s the price of a decent wave. The water temp is about average for this time of year, nothing too wild.

Tuesday the 1st of September is where things get interesting. The morning brings a clean 2ft SSW swell with a very long 18-second period – that’s proper groundswell energy. The wind is offshore out of the ENE, and the wave energy is moderate (448). This is your best bet for the first week. That long period will shape up nicely at Keaulanas, but it might break a bit straight if you’re sitting in the wrong spot. It’s a reef, so it should handle it.

We hit a bit of a lull from Wednesday the 2nd through Friday the 4th. The swell drops off, and the wind is just too strong or cross. The combined energy dips to the low hundreds, and those are just poor conditions. Don’t bother.

Now, Saturday the 5th of September brings a bit more life. The swell jumps to 5ft from the S with a shorter period of 11 seconds. The energy is strong (539), and the wind is cross-off from the E, keeping it clean. It’s a marginal call, but it’s the best of the weekend. That 5ft is getting into the intermediate zone, so it’s not a beginner wave.

The real gem, the one to circle on the calendar, is Tuesday the 15th of September. That’s a full two weeks out, so it’s promising but not locked in, but the data is mouth-watering. The swell is only 2ft from the SW, but it’s a very long 18-second period, and the wind is glassy. The energy is moderate (268), and the conditions are described as “glassy.” That’s the word we all want to hear. For a glassy morning with a tiny, clean groundswell, Keaulanas will be the place to be. It’s a long-range promise, so keep your fingers crossed.

The rest of the second week is a mix of tiny, clean swells and marginal conditions. The 12th and 13th of September have a few sessions with moderate offshore wind and clean conditions, but the swell is too small to get excited about. The 14th brings a light breeze and a small 2ft swell, but it’s a cross-shore wind, so it’s messy.

Overall, the first week is a grind. The best window is Tuesday morning the 1st of September. The second week has a potentially glassy Tuesday the 15th of September that’s the standout. Don’t get your hopes up for big waves, but if you’re patient, there’s a clean, long-period swell waiting for you.

Rusty.
