The Lowdown
Alright, let’s get into it. The outlook for the next 16 days is a bit of a flat spell, I’m not gonna lie. There’s a big gap of nothing surfable to start, and the few moments that show any pulse are still very ordinary. It’s the kind of run where you’d be checking the forecast every day hoping something changes, because right now, it’s not looking good.
First up, we’ve got 13th Ave South Surfside. This spot is an exposed beach break, best with a swell from the SE. It’s inconsistent, and when it does break, it’s a beginner wave, so don’t expect power. The water temp is about average for the time of year.
The first real surfable window shows up on Sunday the 23rd of August in the afternoon. We’re looking at 3 ft from the S, with a short period of 6 seconds, and a clean cross-offshore wind from the WNW. The combined energy is weak (52). It’s surfable, but very ordinary. Not something to get excited about.
Monday the 24th of August morning is a bit better. The swell bumps up to 3 ft from the S, still short period at 6 seconds, but the wind goes glassy – dead calm. That’s clean, and the energy is still weak (97). Still, for a beginner break, 3 ft is about the top of the fun zone before it gets too much. It’s the best of a pretty flat run, but I’d call it a stand-out only because everything else is worse.
Saturday the 29th of August morning has another 3 ft from the S, period 5 seconds, with a clean cross-off wind from the N. The energy is moderate (101). That is the second real highlight, but again, it’s very ordinary. The consistency is poor here, so don’t expect waves rolling through all morning.
The rest of the fortnight is a write-off: tiny 0.7 ft to 2 ft, choppy, onshore, or just no energy. There’s a period from the 18th to the 22nd of August with no surf recommendations at all, and then again from the 25th to the 27th of August. It’s a blank run for sure.
Honestly, the only real standout is the Monday the 24th of August morning session at 13th Ave South Surfside. 3 ft, glassy, clean, and it’s the only time the conditions line up for a proper paddle. Even then, it’s weak and short period, so you’ll have to work for it. The other option is the Saturday the 29th of August morning, but same deal.
Stay patient, keep an eye on the charts, and don’t waste your petrol on the rest of the days.
