The Lowdown
Right, settle in, I’ve had a good look at the charts for Spanish Bay-South Moss. The overall story is a bit of a slow burn, I’m not gonna lie. We’ve got a long stretch of small, marginal surf ahead, with a few windows where it might just be worth a paddle if you’re desperate. The first real action is a week and a half away, so be patient.
The first few days are a write-off. Friday the 7th and Saturday the 8th are tiny, with swells around 1 ft to 2 ft. The wind is light, but the wave energy is weak, and the forecast is basically telling us to stay home. Sunday the 9th sees a pulse of new swell arrive, but it’s a short-period (10 seconds) windswell from the NW, around 5 ft to 6 ft. The combined energy jumps to a moderate level, but the wind is a cross-onshore, making it choppy. It’s a "marginal" call at best. This short-period, sloppy stuff hangs around through Monday the 10th, Tuesday the 11th, and Wednesday the 12th, with heights between 5 ft and 5 ft but the wind stays messy. The water temp is about average for the time of year, nothing to write home about.
Honestly, the only thing that catches my eye happens on the morning of Sunday the 16th of August. The swell drops back to 3 ft but it’s a cleaner long-period SSW groundswell, with a 16-second period. The combined energy is moderate. The wind is blowing offshore from the NW, which should clean it right up. That’s a proper window of opportunity. The swell direction is SSW, which is a little off the optimum W direction, but the offshore wind makes up for a lot. It’s an advanced break, so it’s not for the beginners, and crowds are possible. For a Sunday morning, that’s a decent shout.
The following week from Monday the 17th through to Saturday the 22nd is mostly back to small, unappealing surf with onshore or cross-onshore winds and poor conditions. The highlight is a brief window on the morning of Friday the 21st of August. Again, we get a clean offshore wind from the WNW, but the swell is a mixed bag – a 4 ft, 11-second NW swell and some longer-period energy. The energy is strong, but with the wind being cross-onshore in the afternoon, you’d want to be out there early. The standout is that Sunday the 16th morning session. Get on it.
