The Lowdown
Alright, Rusty here. Let's get into it.
The whole 16-day stretch is all about one spot: Yo Yo's-The Wedge. It's a shallow, advanced reef break, so this isn't the place for learning the ropes. We've got a constant supply of SSW to SW groundswell coming through, which is exactly what this break wants to see. The water's sitting at 79°F, which is pretty much normal for this time of year, nothing weird going on there.
The combined swell energy is strong to very strong, hitting a peak of 3392 on the Tuesday afternoon, and even staying well above 1000 for most of the run. A lot of these swells have periods between 14 and 19 seconds, that's proper long-period groundswell. For a reef setup like Yo Yo's, that means deep, powerful lines that will hold their shape, but the long gaps between sets can mess with your rhythm. The paddle out won't be too bad between sets, though.
Right from the get-go, Sunday September 6th has clean surf with a 5ft SSW swell and a 16-second period, but the forecast points to questionable tide. Monday September 7th picks up a bit more size, hitting 7ft, but the wind swings cross-shore which puts a chop on the face. Tuesday the 8th morning drops a touch to 5ft, but the period stretches to a massive 19 seconds, the longest of the whole run. That afternoon jumps back to 6ft and 18 seconds with a solid 3392 in combined energy. Still, the wind stays cross-shore, so it's not perfectly clean.
Wednesday the 9th is the biggest swell of the early run at 8ft with 16-second periods, but the cross-shore wind sticks around. That size is expert territory, especially on a shallow reef. Thursday the 10th afternoon looks a little better with the wind turning cross-offshore, giving clean 7ft waves with a 16-second period. The energy is still strong at 2318.
The standout early window is Monday September 14th morning. We've got a clean 6ft SW swell at 16 seconds, cross-offshore breeze from the SE at just 9 mph, and the combined energy is solid at 1956. The forecast even calls it "excellent surf conditions for experienced surfers," which is as good as it gets in this run. This is your morning to be in the water.
Further out, Saturday September 19th is worth circling on the calendar. Morning brings 7ft SSW swell with 18-second periods and gentle cross-shore breeze, and the combined energy is 3092. The afternoon cleans up with a cross-offshore breeze and 8ft SW swell at 17 seconds, pushing the energy to 3215. That's the biggest energy reading of the whole period. These are proper, powerful groundswell lines, but at that size, it's strictly for the experienced crew.
Beyond that, the last week of the run holds swell around the 5ft to 7ft range with clean conditions on and off, but the energy tails off toward the end. Monday September 21st afternoon drops to 917 combined energy, which is moderate at best.
A word on the crowds – this spot can get busy, so if you're heading down for a standout session, expect company. And remember, this reef is "very consistent," which is a bonus when the conditions line up.
There aren't really gaps of dead flat here; the swell keeps coming, but the quality of the surf is a mixed bag due to wind and tide.
Rusty.
