The Lowdown

Alright folks, Rusty here. Let's have a look at what Spanish Bay-South Moss has in store for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – the next few days are a bit of a write-off. We're looking at a stretch of poor conditions from Wednesday the 5th through to Saturday the 8th of August. The swell is tiny and onshore, with a cross-on wind messing up the surface. The water's sitting at 58°F, which is about normal for this time of year, but the wave energy is weak (198) and the surf quality is just not there. It's a real bummer.

We finally get a bit of a pulse starting Sunday morning, the 9th of August. The swell bumps up to 5ft from the NW, and the combined energy jumps to a moderate 677. The wind goes offshore, which is a major positive. However, the period is a short 9 seconds, so it's going to be a bit weak and crumbly, not the clean, powerful lines we'd love to see. The conditions are still marginal, with a score of just 1, so it's a gamble. This holds through Monday the 10th with similar 5-6ft NW swell, but with a cross-on wind, it's not going to be clean. The energy stays moderate (683), but the wind is a problem.

Tuesday the 11th sees the swell drop a touch, and the wind is still cross-on, so we're still in the "maybe" zone. The best of this first pulse might be the early morning of Sunday the 9th with that offshore wind, but it's a call for the die-hards only.

Then we get a shift. The swell drops right back down from Friday the 14th of August onwards, with tiny 2ft to 3ft SSW swells. The saving grace here is the period – these are long-period groundswells, reaching 19 seconds on the 14th, and holding around 16 seconds through the weekend. The energy numbers are actually quite good (moderate 500+), but the size is tiny. A spot like Spanish Bay-South Moss, which is an exposed beach setup, is going to struggle to hold that long-period energy. It'll likely be breaking straight and fast. The wind is offshore or light cross-on, so the surface will be clean, but the waves themselves will be small and tricky.

The Standout

If you're desperate for a surf, the absolute best of a mediocre bunch is the Sunday morning of the 9th of August. That 5ft NW swell with offshore wind is the only time the wind and size align. Don't expect perfection, but it's the only window that looks even remotely interesting for a paddle. It's an advanced break, and with 5ft surf, it's going to be pushing it for beginners. The crowds are "sometimes" an issue, so you might have some company. After that, it's a long, slow fade into smaller, longer-period swells that just won't deliver for this spot.

Hang in there, the forecast can always change.
