The Lowdown
Alright folks, Rusty here. Let’s size up the surf. It’s gonna be a quiet one, a real run of ankle-biters. There’s rideable surf if you’re keen, but you gotta work for it and pick your windows. This isn't the week for heroics.
The only spot in town is Lahaina Breakwall/Harbour (Maui). This reef is the go-to, and it’s got its moments. Water temp is right where it should be for this time of year, so no need to stress about the suit.
We start on Wednesday the 9th with tiny 2ft surf. It’s clean with a light cross-offshore breeze, but there’s no punch to it. There’s a bit of a dry spell here as the waves are just too weak. The wind stays light and offshore through Thursday and Friday, but the swell stays minuscule at around 1ft. Good conditions, just nothing to get your heart pumping.
The first sign of life comes on Tuesday the 15th. The swell pushes up to 2ft and the energy picks up. Winds are light offshore, and it’s looking clean. This is where things start to get a little more interesting. Wednesday the 16th afternoon sees the energy jump again with the swell holding at 2ft, and the offshore breeze keeps it glassy. That’s a good sign.
The pick of the week looks like Friday the 18th afternoon. The swell comes up to 2ft with a moderate offshore wind, and the energy is at its highest. That’s the most push we see all week, and it’s clean. This is your best window for a proper surf. The swell direction is from the SW, which is spot on for this break, so the waves should have some shape.
Saturday and Sunday keep things rideable, with 2-2ft swell and light offshores in the mornings. The energy drops off a bit, but it’s still surfable. After that, the bottom falls out. Monday the 21st and Tuesday the 22nd see the swell crash down to under 1ft, and the energy is almost gone. It’s a real lull, and the surf basically vanishes.
There’s a slight bump on Wednesday the 23rd with the swell coming back up to around 1ft, but it’s still weak. The long-range look into Thursday the 24th is poor, with the swell staying under 2ft. Conditions will be clean, but there’s just no grunt.
So, for the week, it’s a waiting game. The standout window is that Friday afternoon, maybe Saturday morning if you’re keen. The waves are small, so it’s fine for beginners, nothing heavy. It’s not a week for charging, but it’s a week for a few clean ones if you're patient.
Rusty.
