The Lowdown
Alright folks, Rusty here. Let’s talk about the surf outlook for Lahaina Breakwall/Harbour over the next couple of weeks.
First off, I gotta be straight with you – it’s a tough start. The water temp is sitting at a warm 80°F, which is about 0.5°F warmer than usual for this time of year, so nothing out of the ordinary there. But the waves? Man, they are tiny. We’re looking at a real flat spell to kick things off. From Tuesday afternoon, July 28th, right through until the morning of Saturday, August 8th, we’ve got a long stretch of just knee-high slop or nothing at all. The combined swell energy is weak, barely cracking 63 on the 28th, and it just drops off from there. The wind is offshore or cross-off most of this time, which is a tease because the water is clean, but there’s just no push to the waves.
The first real sign of life shows up on Saturday afternoon, August 8th. We finally see a little bump, with a 2ft swell from the West, and the energy climbs to 140. The wind is offshore from the NE at 9 mph, so it’ll be clean. It’s still small, but it’s a start. This sets the stage for what looks like the best bet of the whole outlook.
The standout window is the morning of Monday, August 10th. We’ve got a 2ft SSW swell, with a period of 15 seconds – that’s some proper long-period groundswell energy, which means the waves will have shape and power for a reef break like this. The combined energy hits 250, which is a solid moderate punch. The wind is offshore from the ENE at 9 mph, glassy and clean. This is the pick of the fortnight. The crowds here are listed as "sometimes," so you might have a few others with the same idea. It’s still small enough for intermediates, but that long period will make the sets stand up nicely. The Monday afternoon holds up too, with a 2ft SSW swell and offshore winds, just a touch more breeze.
After that, things taper off again. The 11th and 12th of August have some surfable waves, with energy dropping from 182 down to 105, but the conditions are just ordinary. The swell direction shifts to the South for the 12th, which isn’t optimum for this spot.
So, if you’re looking for a window, pencil in the morning of Monday, August 10th. That’s your best shot for a clean, fun session on the reef. The rest of the week is a waiting game.
Rusty.
