The Lowdown

G'day, Rusty here, and I gotta be straight with you—this outlook is a bit of a fizzer for the next couple of weeks. The only spot on the radar is Lahaina Breakwall/Harbour, and it's looking pretty lacklustre. We’ve got a consistent run of tiny, mostly weak swell, and the vibe is more about a paddle than a proper surf.

The water’s sitting at 80°F, so it's about average for this time of year. Nothing to write home about.

Let me break it down for you. The forecast kicks off Saturday afternoon, July 25th, with a little pulse of 2ft SSW swell at a very long 18 seconds. That long period means the waves will have some shape and energy, but at this size, it's more about the glide than the drop. The combined energy is moderate, at 214, and with a clean offshore ENE breeze, you’ll find some clean, peelable little lines. It’s a reef break, and the direction is a touch off the optimum, but it'll be fun if you’re on a longboard or a mid-length. Crowds are sometimes a factor here, so you might share the water.

Sunday, July 26th, is much the same story—2ft SSW swell, dropping to 2ft in the afternoon, and the period slips to 16 seconds. Still clean offshore NE wind, but the energy is fading (184 in the morning, 155 in the arvo). Surfable, but very ordinary.

Come Monday, July 27th, we’re down to 1ft, and the period is 15 seconds. The energy is dropping into the double digits (87 and 86). Still offshore, but the swell is running out of puff. From Tuesday, July 28th, through to the end of the first week and into the second, it’s mostly poor conditions. The swell stays tiny, mostly 1ft to 1ft, with periods ranging from 12 to 18 seconds. The wind stays mostly offshore or clean, but it doesn’t matter when there’s barely a wave to ride.

There’s a tiny glimmer on Thursday afternoon, July 30th, when the energy bumps up to 138 with a 1ft SW swell at 18 seconds, but it’s still very ordinary. The best of the lot is probably that first Saturday afternoon, July 25th, with the 2ft SSW swell at 18 seconds and clean offshore wind. It’s the standout, but only because everything else is flat.

By the second week, from August 1st onward, it’s a dead zone. Swell heights are stuck at 0.7ft to 1ft, and the energy is well below 100. The long period swells (15-19 seconds) are there, but with no size, they’ll barely break. The reef at Lahaina might show a few little lines, but honestly, it’s more of a floating session than a surf. The extreme end of the forecast, Sunday, August 9th, shows a tiny uptick with 1ft SW swell at 17 seconds and 78-89 energy, but it’s still not going to get the heart pumping.

So, to sum it up: the only real shot is the first weekend, especially Saturday afternoon, July 25th, for a clean, longboard-friendly wave. After that, it’s a long stretch of flatness. Keep the board waxed and hope the forecasts change, because this is a pretty blank run for the area.

Rusty.
