The Lowdown

Alright, this is Rusty here, and I’ve been staring at the charts for Spanish Bay-South Moss. Let’s be straight with you – it’s a tough stretch ahead. The swell windows are all wrong for this place, and for an exposed spot that needs a W direction, we’re getting a lot of onshore and cross-onshore wind that’s just going to chop it up.

First up, the water temp is sitting at 57°, which is about 1° colder than usual, so nothing crazy, just a bit nippy for this time of year.

Looking at Thursday the 30th through Saturday the 2nd of August, there’s a bit of swell in the water, 5ft to 6ft, but it’s all coming from the NW and WNW with a short period of 8 seconds. The wind is on it, blowing from the NW and WNW at 9 to 12 mph, so it’s going to be messy and blown out. The energy is weak to moderate (371 to 736), and honestly, the vibe is poor. Not worth paddling out.

Sunday the 3rd of August shows a little more size, 7ft to 8ft, and the period stretches to 9-10 seconds. The combined energy climbs into three digits (940 to 1125), so there’s some push. But the wind is cross-onshore from the W at 6 to 9 mph. This is a marginal call – the waves will have some power, but it’s going to be lumpy and hard to get a clean one. It’s a borderline “maybe” for a confident surfer, but not a standout.

The rest of the first week and into the second week, from Monday the 4th of August onward, the swell drops off. We’re looking at 3ft to 4ft for most of it, with some tiny 2ft to 3ft days later on. The wind stays cross-onshore or cross, and the energy is low (240 to 642). The standout here is the long period swells that start showing up around the 8th of August, with periods of 16-18 seconds, but the height is only 2ft to 3ft. That’s a groundswell with no substance – it’ll be a long wait for a weak, straight-shouldered wave at a beach break. Not worth it.

The best on offer, and I’m stretching to call it a standout, is the morning of Monday the 3rd of August. You’ve got a 8ft NW swell with a 10-second period, light winds from the W at 6 mph, and a combined energy of 1125. It’s the biggest and most powerful swell in the window, but the cross-onshore wind will keep it from being clean. If you’re desperate, that’s your window. But honestly, for most of the 16 days, the setup looks more interesting for a kite surfer than a paddle surfer – consistent wind, decent size, but poor surf quality.

There’s a gap of no real surf from the 4th all the way through to the 14th of August. The swell is small, the period is short, and the wind is never favorable. It’s a blank run.

Rusty.
