The Lowdown
Alright, this is Rusty. Let’s talk about what’s heading our way.
Overall, we’ve got a pretty quiet stretch ahead for Lahaina Breakwall/Harbour. There’s no proper swell on the table - just small, clean lines from the south-west and south-south-west. The real story here is the conditions, not the size. We’re looking at a long run of gentle offshore and light breezes, which means the surface will be clean, but the wave heights are stubbornly small. Don’t expect to get your blood pumping. The water temp is sitting at 27°, which is practically normal for this time of year.
Sunday 23rd August kicks things off with a modest 1ft south-west swell. It’s got some decent period at 15 seconds, but the combined energy is weak at 89. A moderate north-east breeze keeps it offshore and clean - just small and ordinary.
Monday 24th August remains tiny. Morning brings 1ft south-west swell with 14-second period and light east winds, cross-off but clean. The afternoon perks up slightly: the energy climbs to 129, still with 1ft but from the south-south-west. Light cross-off breeze again. It’s clean but you’ll be fighting for scraps.
From Tuesday 25th August through Thursday 27th August, the pattern holds: 1ft to 2ft swell, relentless offshore winds from the north-east or east-north-east, and periods ranging 14 to 17 seconds. The combined energy starts ticking up - Thursday morning peaks at 190. Still, these are small waves. The south-west direction is almost spot on for the reef, but there’s just no power behind it.
Friday 28th August drops off again - 1ft in the morning (energy 97), then a measly 1ft in the afternoon (energy 73). Both clean and offshore, but truthfully, you wouldn’t paddle out for this.
The weekend of 29th and 30th August stays very small. Saturday morning is a write-off with poor conditions and energy down to 55. Saturday afternoon improves slightly: 1ft south-west swell with a 17-second period, but still only 76 energy. Sunday is more of the same - 1ft, 16-second period, offshore breeze, but barely enough push.
The first few days of September are a rinse-and-repeat. Monday 31st August has a brief rain shower and a 0.7ft south-south-west swell with a 19-second period - that’s a long-period groundswell, but it’s so weak it won’t do much at this break. Tuesday 1st September is the best of the run, with 1ft at 18 seconds and combined energy sitting at 170, all under offshore winds. Still, 1ft is 1ft.
Wednesday 2nd and Thursday 3rd September continue the story: 2ft and 1ft swells, light winds, clean faces. Energy is moderate but the height just isn’t there.
The outlook fades toward Friday 4th and Saturday 5th September, with energy dropping into the 40s and 60s. By Sunday 6th September, we see a bump back to 2ft south-west swell with energy up to 161, and Monday 7th September looks like the standout - 2ft south-south-west swell, 16-second period, light offshore winds, combined energy of 200. For this break, that’s as good as it gets in this window. The swell direction is a touch south of optimum, but with such clean conditions and the longest period groundswell, the reef should offer a few lined-up waves for the patient surfer.
But let’s be real: nothing here is substantial. This is a long run of small, clean, ordinary surf. There’s a gap of several days in the second week where things get really weak - particularly around the 3rd to 5th of September. If you’re a beginner, these tiny waves with offshore winds are actually fine. Experts will be bored. The best option is Monday 7th September morning - the biggest of the bunch, glassy conditions, and the most energy. Keep an eye on that one, but don’t kid yourself - it’s still only 2ft.
Rusty.
