The Lowdown

Alright, this is Rusty, and I'm looking at the next 16 days for Spanish Bay-South Moss. To be honest, it's a tough stretch. The water temp is sitting at 58°, which is about 1° cooler than usual for this time of year, so nothing too wild there, just a bit of a chill in the water.

Starting off, we've got a few days of nothing worth paddling out for. The first couple of days are a write-off – small, weak, and the wind is just messing things up. You'll see a few days there with combined swell energy readings in the 100-200 range, which is just weak, and the swell periods are short, under 9 seconds. It's not going to shape up.

Then we hit a bit of a gap. From the 7th to the 8th, the swell is tiny, barely 2 ft, and the wind is blowing straight onshore from the WNW. It's poor, real poor. The energy numbers climb a bit (254-336), but with those short periods and onshore wind, it's just messy.

Now, the first real chance of something rideable shows up around the 9th of August. The swell picks up to 6 ft from the NW, with a period of 9 seconds and the combined energy jumping to 734. That's moderate wave energy, but here's the kicker – the wind is from the WNW at 15 km/h, blowing straight onshore. It's going to be a bumpy, choppy mess. Still, for a bigger-wave surfer, there might be something to work with, but it's not clean.

The best window in this whole 16-day stretch is actually the morning of the 10th of August. We've got the same 6 ft NW swell, but the wind swings to a light cross-on from the WNW at only 10 km/h. That's a major positive. The combined energy is still pumping at 721. It's going to be a little lumpy, but it'll be the cleanest of the bigger days. This is the standout. Go then if you can handle some size and a bit of chop. The afternoon gets a bit windier, so morning is the call.

After that, from the 11th through to the 13th, the swell holds around 6 ft to 6 ft, but the wind is relentless onshore from the WNW, getting up to 20 km/h. The wave quality will be poor. The energy numbers are still solid (in the 600-770 range), but it's blown out. This stretch is more for a kite surfer than a paddle surfer, honestly.

We get a long gap of poor conditions from the 13th afternoon right through to the 18th. The swell drops, the periods get long (15-19 seconds), and the wind is a mixed bag of onshore and cross-onshore. The energy numbers are decent, up to 679 on the 14th, but the wind just ruins it. The long-period SSW swell (19 seconds on the 14th) is prone to breaking straight at a beach setup, so you'd be better off at a point or reef, but we don't have one of those here.

The final stretch, from the 19th of August, looks a little more promising. The swell is small, around 3 ft from the SSW, with a period of 16 seconds. The morning of the 19th has a light cross-on from the NNW, which is a decent wind for this spot. The combined energy is 534. It's marginal, but it's the cleanest thing we've seen in a week. That's your last shout.

So, the bottom line: the best on offer is the morning of the 10th of August. It's not perfect, but it's the only window with decent size and half-decent wind. The rest is a long stretch of blown-out, bumpy, or tiny surf. It's a quiet period, but that's how it goes sometimes.

Rusty.
