Lahaina Breakwall/Harbour Surf Forecast and Surf Report

Alright, I’m Rusty, and here’s the outlook for your local break, Lahaina Breakwall/Harbour.

Right now, we’re looking at a pretty flat start to the forecast period. The first row kicks off on Friday, July 31st, but the surf is just not there. We’ve got a tiny swell, only 1ft, coming from the SW with a very long 16-second period. The combined energy is weak at 122, and the waves are just poor. The wind is a cross-off, so it’s clean, but there’s barely a ripple to ride. This is a reef setup, so that long period groundswell could wrap in nicely if there was any size, but there isn’t.

Saturday morning, August 1st, stays flat. Clean conditions again, but the swell is still 1ft and the energy drops to 80. That’s just not enough to push through. Sunday, August 2nd, is even worse – the swell drops to 1.0ft and energy down to 28. This is a long stretch of near-nothing.

We’ve got a major gap here. From Friday, July 31st, right through until Tuesday, August 4th afternoon, it’s just poor surf. The next couple of days only offer up a score of 1, meaning surfable but very ordinary. Tuesday afternoon, August 4th, we see a little bump: 1.0ft from the SW with a 17-second period, energy at 83. Still weak, but it’s a sign of life. The offshore wind is light, keeping it glassy.

Wednesday, August 5th, is similar. 1.0ft, 15-second period, energy at 71. Conditions are clean with light offshore winds, but the waves are just too small to get excited about. This pattern of small, clean, but weak surf continues for several days. The combined energy stays in the low double digits to triple digits, nothing to write home about.

Then, things start to shift around Sunday, August 9th. The swell picks up to 1ft, period 17 seconds, and the energy jumps to 196. That’s moderate energy now. Monday, August 10th, is the first real standout. We’ve got 2ft from the SSW, a 16-second period, and energy at 261. The wind is light offshore and clean. For Lahaina Breakwall/Harbour, this is a decent window. The swell direction is from the SSW, which is not the optimum WSW, but the long period is still going to wrap in nicely.

The best single session on offer is Saturday, August 15th in the morning. We’ve got 2ft from the W, a 14-second period, and a combined energy of 338 – that’s moderate but the strongest of the whole run. The wind is light and cross-off, keeping it clean. The swell direction is from the W, much closer to the optimum WSW. This is the one to circle on your calendar. It’s not a monster, but for this spot, that’s the best you’ll see.

Tuesday, August 11th afternoon, we see a bit of a drop, with energy fading to 176 and the swell shifting back to SSW. The wind picks up a little, and it’s not as clean. After that, we’re back to small, clean, but ordinary surf for the rest of the second week. By Friday, August 14th afternoon, the energy has dropped back to 107.

So, the best bet is that Saturday morning, August 15th. It’s the only session that really stands out with a good swell direction, moderate energy, and clean conditions. The rest of the time, it’s a waiting game for a little more size. The water temperature is about average for this time of year, so no surprises there.

Rusty.
