The Lowdown
Alright folks, Rusty here. Let's see what we've got on the menu for the next couple of weeks.
Right off the bat, we're looking at a pretty flat start. The first few days are offering up tiny, weak waves that are surfable, but honestly, nothing to get excited about. You’ll be scratching around for knee-high dribbles, and while the wind is offshore, it’s not enough to save the day. The combined energy is sitting in the low to moderate range (124 to 168), which tells you it’s pretty limp. The water temp is a super comfortable 80.6°, which is bang on average for this time of year, so you won't need a thick suit.
Things start to look a little more promising as we head into the weekend and the start of the new week. From Saturday the 5th into Sunday the 6th, we see the swell nudge up a touch to 2.6 ft, with a period of 11-12 seconds. The energy climbs a bit more (218 to 235), and with light offshore winds from the NE, it’ll be clean. It’s still not going to be pumping, but it'll be a lot more fun than the earlier dribble.
Now, the standout window is shaping up for the second week. Monday the 7th starts to show some real promise with the swell energy jumping to 365 and a nice 16-second period from the SW. That’s a proper long-period groundswell, and it’s going to be clean with light offshore winds. The headliner, though, has to be Sunday the 13th. We’ve got a solid 5.9 ft to 6.6 ft swell rolling in from the SW, with a period of 12 seconds. The combined energy is massive, hitting 895 in the morning and a whopping 1112 in the afternoon. That is strong wave energy. The wind is forecast to be light, offshore, or even glassy. This is an expert-level wave, though, so if you’re not comfortable in overhead+, powerful surf, give it a miss. For the experienced crew, this is the best day on offer, but it's a week and a half away, so keep your fingers crossed.
The days after that drop off quickly, with the swell fading and the energy tanking back down to below 100 by the 16th.
So, to sum it up, the best bet is Sunday the 13th at Lahaina Breakwall/Harbour. It’s a reef break, so it should handle the long-period swell well, and with that 6.6 ft of SW swell and clean offshore winds, it’s going to be a proper session for the big-wave boys. The water is warm, and the crowds are possible, but that’s a price worth paying for that kind of quality. The setup is more interesting for paddle surfing, not kiting.
