The Lowdown

Alright, Rusty here. Let’s take a look at what’s cooking for the next couple of weeks.

Right off the bat, the vibe is pretty mellow. We’ve got a consistent run of small, clean surf, but nothing that’s going to get your heart racing. The standout—if you can call it that—is Lahaina Breakwall/Harbour. The water temp is sitting around 81°, bang on average for this time of year, so no surprises there.

Starting Sunday the 13th, we’ve got tiny 1 ft swell with a long 15-second period pushing in from the SW, and light offshore NE winds at 6 mph. The combined energy is on the weak side at (55) – that’s not much to work with, and the conditions are clean but honestly the surf is poor. Same story into Monday the 14th: 1.0 ft swells, still long period, but the energy ticks up a notch to (106) Monday afternoon, and the offshore breeze stays in the NE at 9 mph. It’s surfable but very ordinary.

Now, Tuesday the 15th morning sees a tiny bump – 2 ft from the SW, 20-second period – that long period means it’ll have some shape, but at a reef setup like Breakwall, it can get a bit straight. Energy’s moderate at (188) and the NE winds are light and offshore. Still, it’s not enough to call it a proper session.

Wednesday the 16th into Thursday the 17th is more of the same: 2 ft to 2 ft swells, moderate energy (222 is the best we see Wednesday afternoon), and consistent offshore NE winds. Clean, but small. Crowds are a possibility here – it’s a “sometimes” spot, so you might have company on those rare fun waves.

The pattern holds right through the first week and into the second. Friday the 18th through Monday the 21st keeps the 2 ft to 2 ft range, with light to gentle offshore or cross-off winds. Energy stays moderate, topping out around (248) on Friday morning. But the surf is described as “very ordinary” or “poor” – it’s just not doing enough.

By the second week, we’re still stuck in the same groove. Monday the 22nd to Thursday the 24th has 1 ft to 2 ft swells, still offshore, still clean, but tiny. Energy drops into the low 100s. Friday the 25th through Sunday the 27th doesn’t change much. Monday the 28th finishes the run with 1 ft from the SW, a longer 19-second period, and energy at (189) – it’s clean and surfable, but again, very ordinary.

Bottom line: if you’re dying for a paddle and just want clean, tiny waves with no crowd pressure and glassy conditions, Lahaina Breakwall will give you that most days. But for any real push, you’re out of luck. The best bet might be the afternoons between the 15th and 18th where the energy is a bit higher, but don’t expect much more than knee-to-waist high dribblers.

Rusty.
