The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks.
The short story is, we’ve got a real long spell of small, weak swell ahead. The first surfable pulses don't start showing up until early August, and even then, it’s not going to get you out of bed. The real standout of the whole 16-day window is tucked away at the very end. Let’s walk through it.
The first recommendation is for Lahaina Breakwall/Harbour on Friday afternoon, July 31st. There’s a tiny 1 ft SW groundswell rolling in with a nice long 16-second period, and the combined energy is a weak 115. The wind is blowing offshore from the NE, which is clean, but the waves are just too small. Water temp is sitting at 80°, which is about normal for this time of year.
We then hit a big gap. From Saturday, August 1st, all the way through to the morning of August 8th, the forecast is pretty much a no-go. The swell drops to 0.7 ft on some days, and the energy readings are pathetic, often in the double digits. Conditions are "poor" across the board. That’s a long stretch of small, flat days.
Things start to stir a little on Saturday morning, August 8th, with a 1.0 ft SW swell, period 18 seconds, and the energy finally climbs to 105. It’s still very small, but the offshore wind is clean. The following Sunday morning, August 9th, the energy jumps to 210 and the swell bumps up to 1 ft SW. The wind is light offshore (NE 9 mph), and the water is clean. It’s surfable, but still very ordinary.
The real standout, the one you want to circle on the calendar, is Wednesday afternoon, August 12th. The swell is only 1 ft, but it’s coming from a nice SSW direction with a 18-second period. The combined energy hits 278, which is the strongest of the whole forecast. The wind is offshore from the NE at 9 mph, making for clean, groomed lines. This is the best on offer. It’s still small, but the quality is there. The long-period groundswell (18 seconds) will have lovely shape and energy, but at a point break like this, it’s going to be a treat. Crowds are possible at this spot, so you might have some company.
Thursday morning, August 13th, also has similar energy (277) with a 2 ft SSW swell, but the wind is cross-off, not quite as clean as the day before. The rest of the run into the 15th has some small, inconsistent pulses, but nothing to light up the beacon.
So, bottom line: the next week and a half is mostly flat, with a few tiny, clean days. The one true stand-out is Wednesday the 12th at Lahaina Breakwall/Harbour. It’s small but clean, with the best energy of the run. Don’t get too excited about the rest.
Rusty, signing off.
