The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks.
I gotta be honest, the first week is pretty flat. The first real surfable day is Saturday the 10th of August, and even then it’s small. We’re talking waves around 1 to 1 feet from the SSW, with combined energy (112-129) that’s weak. The wind is offshore, which is a big plus for clean waves, but there’s just not enough push to get your heart rate up. It’s a long wait for a knee-high wave.
Things start to look a little more interesting from Wednesday the 12th of August. The swell is still modest, but it climbs to about 2 feet from the SSW, with a period of 18 seconds. That’s a proper long-period groundswell, bringing clean, powerful energy. The combined energy reading (273) is moderate, so there’s a bit more life in the water. The winds are cross-offshore, keeping it clean. The best of this period looks like Wednesday the 12th morning, and again Thursday the 13th morning, with a steady NE offshore breeze and 2 feet of SSW swell (269 energy). This is the standout window. For a protected reef like Lahaina Breakwall/Harbour (Maui), that long-period SSW groundswell is the ideal direction, and it should wrap in just right. The water’s sitting at a warm 80°, which is about average for this time of year, so no surprises.
The week after, on Monday the 17th of August, we see another bump. The swell is up to 2 feet from the WNW with a 16-second period. The combined energy jumps to 279, and we’ve got a light offshore breeze in the morning. That’s a promising long-range call, but it’s a bit far out to lock in. The direction is shifting, so keep an eye on it.
Overall, the best bet is the morning of Thursday the 13th of August. It’s not gonna be a massive day, but with that consistent offshore wind and a clean, long-period groundswell wrapping into the harbour, it’s the pick of the bunch. The crowds are likely here, as it’s a consistent spot, but for a clean, long-period swell, it’s worth the company.
Rusty.
