The Lowdown
Alright folks, Rusty here. Let’s break down the next couple weeks around Lahaina Breakwall/Harbour. It’s gonna be a slow go, but there’s a little window of hope if you’re willin’ to wait.
Right off the bat, we’re in a flat spell. The water temp is about average for this time of year, no surprises. The first few days through the end of July and into early August are tiny. We’re talkin’ 1 ft of swell, with a super long period of 18 seconds, but the energy is weak – only 109 (moderate energy) at best. The wind is cross-off or offshore, keepin’ it clean, but honestly, it’s just very ordinary. Nothin’ to get excited about.
We’ve got a gap of several days here where the scores are real low. The swell drops to 0.7 ft and 1.0 ft, the energy falls into the double digits, and it’s just poor surf conditions. The wind stays offshore or light, which is a cruel joke – clean waves that are barely there. You could maybe snag a knee-high slide on the afternoon of August 4th when the period jumps back to 17 seconds, but the energy is only 70. It’s a tease.
The next bit of life shows up on August 8th. Through the weekend, we start seein’ that swell tick up to 1 ft, and the energy is climbin’ back into the low hundreds. By Sunday the 9th, the afternoon shows 2 ft from the SW with a 17-second period and energy up to 240 (moderate). That’s gettin’ better, but still very ordinary.
Now, here’s the standout. Monday the 10th of August is the real deal. Morning and afternoon both show “expect good surf conditions.” The swell bumps up to 2 ft to 2 ft from the SSW, with a period of 15-16 seconds. The energy jumps to 305 (moderate). The wind is offshore and light, so it’s gonna be clean. This is the best on offer. For a reef break like Lahaina Breakwall, that long-period SSW groundswell will wrap in nice and clean. Keep in mind, with a period over 15 seconds, the sets will be spaced out, but the shape should be there. It’s still a small wave, fine for all levels.
After that, the 11th and 12th drop back to 1 ft-2 ft and ordinary conditions. The 11th afternoon has a glassy moment though, which is always a treat. The 13th and 14th are back to 1 ft-2 ft with cross-off winds, nothin’ special.
So, the long and short of it: if you’ve got a paddle on the 10th of August, you’ll be rewarded. The rest of the window is a waiting game. The break is consistent, so when the swell shows, it’ll be on. Crowds are a possibility – this spot can get busy when it’s clean.
Rusty.
