The Lowdown
Alright, folks. Rusty here, checkin' in from the islands. Let's get into what's on the menu for the next stretch.
Alright, so we're lookin' at a pretty quiet picture for Lahaina Breakwall/Harbour. The next two weeks are mostly about small, clean, but very ordinary waves. We've got a run of weak energy and small swell, but there's a little pulse of something worth paddling out for later on.
The water temp is sittin' at 80° which is right on the money for this time of the year, so no need for a thick wetsuit.
The first proper action, and really the standout, is on Friday, July 24th afternoon. The wind goes offshore from the NE at 12 mph, makin' it clean. You'll see small 2 ft waves from the SW, with a period of 17 seconds. That's a long period groundswell, which is sweet, but it'll be a bit slow and fat on the sets. The combined energy is moderate (216). It's not gonna blow your mind, but for a clean, small wave session, it's the best on offer.
Saturday, July 25th is also worth a mention. The morning has a gentle offshore from the ENE at 9 mph, with 1 ft SSW swell and a 16-second period. It's clean, but small. The afternoon picks up a little, with 2 ft SSW swell and a nice 18-second period, with a moderate offshore breeze from the NE at 12 mph. The energy is moderate (214). Again, nothing huge, but you can get a few long, clean lines.
After that, the energy drops right off. From the 27th of July through to the 4th of August, it's a long stretch of tiny, weak surf. The swell barely reaches 1 ft most days, and the combined energy is mostly weak, with values in the 60s, 80s, and even down to 16. It's a long gap of poor conditions. The wind is often offshore, so it's clean, but there's just not enough water to get excited about.
Then, on Thursday, August 6th, we see a little change. The swell direction shifts to the WNW, with 1 ft swell and a 15-16 second period. The wind is a light cross-offshore from the ENE or E, so it's clean. The combined energy bumps up to a moderate 121-124. It's still small, but it's a different direction and a little more push.
The best of the whole run, though, is Friday, August 7th. The morning has a 2 ft swell from the W, with a 15-second period, and a gentle offshore from the ENE at 9 mph. The energy is a moderate 206. The afternoon is similar, with a 2 ft W swell, and a moderate offshore from the NE at 12 mph. The energy is 195. This is the pick of the litter.
The breakwall is a reef, so those long period swells will set up nicely. It's a consistent spot, so it'll be breaking, and the crowds are "sometimes" there, so you might have a few buddies out. But with such small waves, it won't be packed.
This is a period for the longboard or the foily, not for charging. The best bet is to keep an eye on that Friday, August 7th window.
Rusty.
