The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks. It’s a bit of a slow burn to be honest. The good news is we’ve got clean conditions with a light offshore breeze hanging around, but the waves themselves are struggling to get going. The first few days, right up to the 15th, are looking pretty flat and frustrating. We’re talking ankle-biters, mostly around 1 to 2 feet, and even though the wind is favourable, there’s just not enough push in the water. The swell energy is weak, reading between 89 and 281 in the combined energy, so it’s going to be a lot of grovelling for not much return. You’d be better off sorting out your gear than paddling out for those.
Now, there is a glimmer of hope. On Sunday the 16th, things finally start to wake up. The morning is the standout of the whole run. The swell jumps to 4.3 feet, with a period of 12 seconds, and the energy reading is up at 498, which is a solid jump. This is the one to circle on the calendar. Lahaina Breakwall/Harbour (Maui) will be the place to be. The swell is coming from the south, which is just about on the money for this spot, and with that lovely gentle offshore breeze, it should be clean and lined up. It’s not huge, so it’s going to be a fun, accessible size for most, a real breath of fresh air after all that nothing.
After that little pulse, it fades away quickly. The rest of the second week, from the 17th onward, drops back off again. We’re back to those small, 1 to 1.5 feet waves with only moderate energy readings. There’s a shift in direction, with some west-northwest swell trying to mix in, but it’s not going to save the day. You get some clean mornings with light winds, but it’s really just more of the same small, weak surf. There’s nothing on the horizon that looks like it’ll kick up another proper swell in the second week, so if you want a wave, the 16th is your day. Don’t hold your breath after that.
