The Lowdown
Alright, let’s get into it. The first week is a write-off, but hold tight – there’s a solid window opening up.
We start off pretty flat at James Kealoha Beach Park. From Sunday the 13th right through to Wednesday the 16th, it’s all poor surf conditions with tiny, weak swell. Winds are mostly onshore or cross-onshore and the energy is low – nothing worth paddling out for.
The first real glimmer shows up Thursday morning the 17th. Swell pushes up to 7ft from the ENE, period is a short 9 seconds but the wind goes light and cross-offshore, cleaning things right up. That’s a genuine standout for the whole outlook. The combined energy is moderate at 741. It’s a reef break that can handle the size, but at 7ft it’s getting solid – best for experienced surfers. Water temp is 81°, about average for this time of year. That clean, cross-off wind is a major positive, meaning smooth faces and proper lines.
Friday the 18th and Saturday the 19th keep the goodness going – swell hangs around 6ft to 6ft from the E/ENE, still with light cross-off winds in the mornings. Energy stays moderate (386 to 439). Good surf conditions on offer, just not quite the standouts that Thursday is.
Sunday the 20th starts to back off a touch – swell drops to 6ft but the wind turns cross-onshore, so quality dips. Monday the 21st is back to poor with onshore wind and choppy conditions.
Now, there’s a gap of a couple days of marginal stuff, then Tuesday the 22nd gets interesting but tricky. Swell jumps to 8ft from the E with a longer 13-second period, combined energy strong at 2011 – that’s a powerful groundswell. But it’s cross-shore wind and the guidance calls it marginal. At 8ft, that’s expert territory. The long period means it’ll be lining up better for a point or reef, but with the onshore component it won’t be clean. Wednesday the 23rd keeps the size at 10ft but again onshore and choppy – not the best for paddle surfing, could be more of a kite session.
From Thursday the 24th through to the end of the month, it’s mostly poor to marginal with cross-onshore winds and dropping energy. Not much to get excited about after that initial Thursday-to-Saturday window.
So, the clear standout: Thursday morning, September 17th at James Kealoha Beach Park – 7ft ENE swell, light cross-offshore wind, clean conditions. That’s the one to circle. Friday and Saturday mornings are good backup, but Thursday is the pick.
If you’re a beginner, that Thursday size is a bit much – stick to the smaller morning windows on the 18th or 19th when it’s around 6ft. Crowds are possible at this spot, so get in early.
