The Lowdown

Alright, Rusty here again. Looking at this 16-day window, I’m telling you straight – it’s a bust. There’s no real surf worth chasing. The whole run is a grind of onshore wind and junky waves.

We’re stuck with Spanish Bay-South Moss – an advanced break that’s fairly consistent, but that’s about the only positive. Water temp is about normal for now. From Thursday August 13th right through to Friday August 28th, it’s a mess. Wind is cross, cross-on, or straight onshore from WNW and NW, hitting 15 mph, sometimes 16 mph. Swell is mostly 2 ft to 6 ft, with short periods of 7 to 8 seconds. That’s weak, choppy, and won’t hold a face. Wave energy is moderate to strong, but with that wind and period, it’s just messy.

There’s a tiny bit of long-period SSW groundswell on August 14th and 15th – 19-second period – but it’s only 2 ft to 3 ft and the wind is onshore. That’s not surf. On August 24th, another 0.5 ft 18-second groundswell pops up, but again, tiny and blown out.

Only two mornings get a “marginal” nod: August 14th morning (2 ft, 19 sec SSW, WNW 5 mph – near glassy but flat) and August 27th morning (5 ft, 8 sec NW, 9 mph onshore – blowy and short period). Neither is worth the drive.

This is a solid 15-day dry spell. If it were a beach-and-reef setup like this, with all that wind and swell, it’s looking more like kite-surfing conditions than paddle-surfing.

Hang tight, things can change, but for now, leave the boards at home.

Rusty.
