The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a flat spell for the most part. The first decent chance comes on Friday 14th August, but the rest of the time you’re fighting onshore winds, small swell, and choppy conditions. Not a lot to get excited about, but let’s break it down.
Spanish Bay-South Moss (Spanish-Bay-South-Moss) is the only spot in the mix, and it’s an advanced wave. The water sits at 60°F with a slight anomaly of 0.5°F – about average for this time of year, no surprises there.
The real standout is Friday 14th August morning. The swell is tiny at 2 ft, but it’s coming from the SSW with a very long period of 19 seconds – that’s proper groundswell energy. The wind is glassy, clean as a whistle. Combined energy hits 472 (moderate), but with those long gaps between sets, it’ll be a clean, mellow session. Just don’t expect much push. The long period will suit a point or reef better than a beach break, but with the glassy conditions, it’s still the best moment of the whole run.
Thursday 13th August morning is almost worth a look – 5 ft from the WNW at 8 seconds, but the wind is cross-shore and there’s a slight chop. It’s marginal, but if you’re desperate, it’s the biggest swell of the early period. After that, the wind turns onshore and stays onshore for days.
From Saturday 15th August all the way through to Wednesday 26th August, it’s rough. The wind is mostly onshore or cross-onshore, and the swell drops to 1 ft to 3 ft, with weak combined energy (mostly under 500). The long-period SSW swells keep coming, but they’re small and blown out. The period hits 14-19 seconds at times, so there’s energy, but it’s not breaking clean. That kind of period is best at a point or reef, but with the wind messing it up, it’s not worth paddling out.
Honestly, for the whole 16-day window, the only morning that stands out is Friday 14th August. If you’re an advanced surfer and you don’t mind tiny waves, it’s the one. Otherwise, you’re better off waiting for the next system.
Rusty.
