The Lowdown

Alright, Rusty here. Let's talk about what's on the cards for Spanish Bay-South Moss.

Look, I'm not gonna sugarcoat it – the next few days are a grind. We've got a bit of swell showing up, but the wind is just not playing ball at all. For the first ten days or so, it's a constant onshore or cross-onshore breeze, which is going to chop everything up. It's not the kind of surf you write home about. The water is also a bit colder than we'd expect for this time of year at 57°F.

We start off on Friday the 31st of July with a 5ft NW swell, but it's a short 8-second period and that 12 mph WNW wind is just ruining it. Saturday the 1st of August is more of the same with a bit of a bump in size to 6ft, but the wind still has us onshore. The combined energy is moderate, hitting 500, but it's not translating to quality.

Sunday the 2nd of August actually sees the swell build to 7ft from the NW, with a slightly better 9-second period and a lighter wind on the morning. The combined energy jumps up to 889, which is getting into a strong range for this spot. But the wind is still onshore, and the forecast calls it marginal. This is only for the more advanced crew who don't mind a bit of a wrestle.

Monday the 3rd and Tuesday the 4th offer a similar story – plenty of NW swell around the 7ft mark, with strong energy levels (918 on Monday morning), but the wind swings cross-on. It's a fight, not a glide.

It's not until a bit later in the window that things get interesting. On the 12th of August, we see a tiny 2ft swell from the SSW, but the period jumps to a very long 16 seconds. That's a proper groundswell pulse. The energy is still moderate at 404, but with a long period like that, you need a spot that can handle it. For a beach break, a long period like that can make it break a bit too straight, but if you find a bank, it could be fun.

The real standout, though, is shaping up for Saturday the 15th of August. The morning sees a 3ft groundswell from the SSW, with an incredible 18-second period. That's as long as it gets. The combined energy is a solid 596 (moderate), but the kicker is the light cross-shore breeze. It's a clean, lined-up day if the swell direction lines up with the bank. The water will still be cold, but this is the one to circle on the calendar. It's a long way out, so don't book the trip yet, but it's got promise.

So, the honest truth? The first week and a half is a write-off for clean, fun waves. The best bet is that Saturday the 15th of August morning session. It's small, but it's clean and has that long-period energy that makes the paddling out easy.

Rusty.
