Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright, let’s get into it. The surf’s looking pretty mellow for the next couple of weeks here at Lahaina Breakwall/Harbour (Maui). The water’s sitting at 80°, about 0.7° warmer than normal for this time of year—nothing too wild, just a touch above average for this corner of the island.

Right now, we’re kicking off the period with small, clean waves but nothing to write home about. Tuesday, August 11th, we’ve got thigh-high stuff around 1 ft to 2 ft from the SSW, with a light cross-off breeze making it look tidy. The swell energy is low, around 101–129, so it’s more of a longboard cruise or a learner session than anything with punch.

Wednesday, August 12th, is where things pick up a little. The swell stays small at 2 ft, but the period jumps to 18 seconds—that’s a proper long-period groundswell pushing in from the SSW. The wind flips to a light offshore, and combined energy climbs to 283. That’s moderate energy, and with glassy conditions it’ll feel more fun than the size suggests. This is the standout window early on. If you’ve got a log or a fish, Wednesday morning is your call.

Thursday through Saturday, August 13th–15th, the swell drops a touch and the period shortens. Winds remain offshore, but the height hangs around 2 ft to 2 ft, and energy slides from 240 down to 105. By Saturday, the breeze picks up to 18–22 mph—still offshore, but it’s a fresh breeze that’ll make the surface lumpy. Not great. Then Sunday, August 16th, we’ve got a strong offshore breeze at 25 mph, with rain showers. Combined energy is 134, but the swell is only 1 ft. It’s clean but hard to paddle into, and the quality is poor. Monday, August 17th, is back to tiny, ordinary surf with light cross-off winds.

There’s a decent gap of mediocre days here, but things start to look up again further out. On Tuesday, August 18th, there’s a brief spike to 3 ft from the NW with a short 8-second period and light offshore winds—energy is 142, so it’s not huge, but it’s a different direction and could offer a few fun runners if the thunderstorms stay away.

Then from Wednesday, August 19th, to Sunday, August 23rd, we’re back to very small swell—1.0 ft to 1 ft—with periods ranging from 12 to 18 seconds. Winds are mostly light offshore or cross-off. Combined energy is low, mostly under 100. It’s a real flat spell, but the consistency is there for a micro-session if you’re desperate.

Finally, we’ve got a promising finish. Monday, August 24th, starts to build again with 1 ft from the SSW and an 18-second period, energy hitting 235. Tuesday, August 25th, is the standout of the second week: 2 ft from the SSW, 16-second period, light cross-off winds, and combined energy at 299. That’s moderate energy, and the conditions should be clean and inviting. Wednesday, August 26th, holds well with 2 ft to 2 ft from the SSW, 17–18 second period, light offshore winds, and energy around 283–296. These last few days are the real deal for this forecast—small but clean, consistent, and with that long-period glide.

Overall, the best bet is Wednesday, August 12th, for the cleanest combo of offshore wind and long-period groundswell, even if it’s small. The second week’s standout is Tuesday, August 25th, but it’s a long way out, so keep an eye on it. If you’re after bigger juice, you’ll have to look elsewhere—this stretch is all about finesse.
