The Lowdown
Alright, let’s get into it.
The window opens with a bit of a slow start, but there’s solid swell on the horizon. The first call is for Sunday morning, and it’s a bit of a mixed bag. We’ve got a 7ft SSW swell rolling in with a 16-second period, but the wind is cross, not offshore, so the surface is going to have some bump on it. It’s not terrible, but it’s not the clean glass we’re after. The energy is strong though, with a combined reading of 2080, so there’s plenty of push. Water temp is 80°, which is about normal for this time of year, so a rashie is all you need.
Later Sunday afternoon, that same swell drops slightly to 6ft but the wind swings to a cross-off and cleans it right up. This is where it starts to get interesting. The energy is still strong at 1756. This is a better window for the more experienced crew.
Monday eases off a bit. Swell drops to 5ft in the morning, and the period shortens to 14 seconds. It’s still rideable, but the energy is down to 985, which is moderate at best. The afternoon sees a bit more wind, but it stays cross-off. Not the day to write home about, but there are waves.
Tuesday morning has a little pulse of energy with a 4ft swell but a long 16-second period. The combined energy is actually higher than you’d think at 1961, but the wind is light cross and the surface is a bit rippled. The afternoon is much better. It’s 5ft, the wind goes cross-off, and the energy jumps to 2434. This is a clean, fun option for the experienced surfer.
Now, listen up. Wednesday is where it starts to get real. The morning shows a 8ft SW swell with an 18-second period and energy at 3564. The wind is still cross, so there’s a bit of texture. But the afternoon is the standout of the first week. 8ft of SW groundswell, 18-second period, cross-off wind, and energy at 3829. This is clean, powerful, and definitely one for the advanced crew. This is the pick of the first stretch.
Thursday holds that same size and quality. Morning is 8ft at 16 seconds with cross-off wind and energy at 3898. This is right up there with Wednesday afternoon. It’s a full-on day. Afternoon eases just a touch, but it’s still solid.
From Friday on, it backs off a little, but it doesn’t die. We’re looking at 6ft to 8ft on Friday with a fresh breeze in the afternoon. The surf stays consistent through the weekend and into the start of the next week. The swell drops a bit to the 5ft to 6ft range during the middle of the following week, but the energy stays moderate. Nothing that will have you calling in sick, but there’s always something to ride.
The standout by far is Wednesday afternoon through Thursday morning. Big, clean, powerful SW groundswell. It’s going to be pushing 8ft, which is serious size. This is not for beginners. You need to know what you’re doing. The long 18-second period means it’s going to be a proper groundswell, and at this reef break, it should line up nicely. The cross-off wind is going to make it look like a postcard. If you can only pick one window, that’s it.
Keep in mind, a 16 to 18-second period is long, so the sets will be well-spaced. That can make paddle-outs a bit easier, but the power is serious. This is a spot for the experienced surfer.
As we get further out, into the last few days of the month, the swell stays in the 4ft to 7ft range. The energy is moderate, and the wind is mostly cross-off. It looks like the surf will stay rideable, but nothing will match that Wednesday-Thursday push. It’s a promising long-range call, but as always, the further out we look, the less certain it is.
So, gear up for Wednesday afternoon and Thursday morning. That’s the one to chase.
