The Lowdown
Alright folks, Rusty here. Let's look at what's ahead for Lahaina Breakwall/Harbour. It’s a mixed bag, but we’ve got some clean, small-wave windows to work with.
The water temp is sitting at 80°, which is pretty much average for this time of year around here, so no surprises on that front.
We kick things off on Friday morning, the 7th of August. It’s tiny, with a mere 1.0ft of swell from the SW, but the wind is light offshore from the NE, keeping it clean. The energy is weak (40), so you’ll be fighting for a dribble, but it’s a paddle. The afternoon stays clean with offshore breeze, though the swell drops to 0.7ft.
Saturday the 8th stays in that same rut – 1.0ft on Saturday morning with a cross-offshore wind, so the surface is clean but the waves are gutless. Sunday the 9th sees a small bump, with 1ft on offer in the morning and the energy climbing up to a moderate 143, still with clean conditions from a gentle offshore breeze. This pattern of clean but small holds through the first week.
The standout window really starts to build from Wednesday the 12th, August. The swell ticks up consistently, hitting 2ft by Wednesday afternoon, with that combined energy jumping into the 200s (252). The wind stays offshore and clean from the NE – that’s a major plus, giving you clean shoulders on a reef that needs all the help it can get. This is the best run of the whole outlook. The swell holds through Thursday the 13th and Friday the 14th at 2ft to 2ft, with offshore winds and moderate wave energy.
Forget the second week’s tiny dribbles – from Saturday the 15th onward, the energy drops off a cliff. There are glimmers (1ft on Sunday the 16th, 1ft on Tuesday the 18th) but the juice just isn’t there consistently. The very end of the outlook, around the 22nd, shows a slight lift back to 1ft with light, clean winds, but don’t expect much.
So, if you are picking a moment, Wednesday the 12th through Friday the 14th of August is your best bet. The swell is small and clean, the offshore wind is your friend, and the break isn’t going to be packed. It’s not a bombing day, but for a clean, playful reef session on the smaller board, that’s the call.
Rusty.
