Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for this stretch of coast.

The forecast shows a bit of a slow start with small, but clean, waves before a solid pulse of energy rolls in around Monday the 7th. The best action is definitely that Monday into Tuesday, but there’s a trade-off with the wind. After that, it settles back into small, clean conditions for the long haul, with a few more interesting days way out in the second week.

We kick off on Saturday the 5th with tiny 3ft SSW swell, but the wind is light offshore from the NE. It’s clean, but the energy is weak (230). Honestly, it’s a small day for a longboard or a beginner session. The water temp is 80°, which is pretty much bang on average for this time of year, so no wetsuit needed.

Sunday the 6th stays similar – 3ft from the SW, but the wind swings cross-offshore from the ENE. The swell energy is still moderate (193-227). It’s surfable, but nothing to get excited about.

Now, Monday the 7th is where things get interesting. The swell bumps up to 4ft in the morning from the SW, with a 13-second period, and the energy jumps to strong (599). By the afternoon it’s 5ft from the SW with a 14-second period and energy cranking up to 902. The wind is a cross-offshore breeze from the E/ESE, keeping it relatively clean. The water temperature remains about normal. This is the standout period for the whole outlook – a proper groundswell pulse with moderate energy and good shape for the reef.

By Tuesday the 8th, the swell peaks at 6ft from the WSW in the morning, with a 12-second period and very strong energy (1273). But here’s the catch – the wind swings cross-onshore from the SSE. That’s going to chop it up. For experts only, and even then, it’s a bit of a messy affair. The afternoon drops to 6ft but still with cross-onshore wind. Conditions are poor for paddling, but if you’re into kiting, the setup looks more interesting.

Wednesday the 9th sees the swell drop back to 2ft from the SSW, with the wind turning light and cross-offshore again. It’s clean but small, with moderate energy (153-168). A good day for a mellow session.

From Thursday the 10th, right through to the 13th, we’re in a real lull. Swell drops to 1ft and even 1ft, with energy values below 100. The wind stays light offshore or cross-offshore, so it’s glassy, but there’s just no wave power. This is a gap of several days with no real recommendation.

Then, from Monday the 14th through to Saturday the 19th, a very long-period, deep-water swell starts showing up. Swell heights are still small – 1ft to 2ft – but the period is long, sitting between 14 and 23 seconds. The energy climbs back to moderate (118-277). The wind is consistently offshore or light cross-offshore. On Monday the 14th, the period hits 23 seconds, which is very long, and the energy jumps to 118. These long-period swells can be tricky at beach breaks, but for a reef setup like this, they can produce some nice, clean lines. The best of this second week looks like Friday the 18th with 2ft SW swell, 19-second period, and gentle offshore wind, giving an energy of 277. It’s clean, but still small. The period is so long that the sets will be widely spaced, making paddling out easier, but you’ll be waiting.

Lahaina Breakwall/Harbour (Maui) is the spot here. It’s a consistent reef break, and the optimum swell direction is WSW. The best window is the Monday the 7th pulse. For the second week, the Friday the 18th offers the cleanest conditions, but it’s a long-range call, so keep an eye on it.

Stay stoked, and I’ll catch you down the line.
