The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s heading our way for the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. The first real sign of life doesn't show up until Tuesday the 8th, and even then it’s not exactly a celebration. We’ve got a long gap of poor conditions from now until then, with nothing worth paddling out for.

The only spot that even gets a mention is Narrabeen-Alley Rights. Tuesday afternoon the 8th brings a bit of a pulse, with a swell coming in at 8 ft from the SSE. That’s a solid size, but it’s a direct onshore wind from the SE at 9 mph, so it’s going to be a messy, lumpy beast. The swell energy is strong (1722), and the period is a short 11 seconds, so it’s gonna be a thumping, choppy wall of water. This one is for experts only, and even then, it’s a battle. The water temp is about average for the time of year at 64°F.

The rest of the period is a real mixed bag of tiny, weak, and wind-affected leftovers. Saturday the 12th morning has a tiny 1.0 ft SSE groundswell with a very long 19-second period, and glassy conditions. That’s a lovely idea, but the energy is weak (93) and the swell is just too small to do anything with. It’s more of a meditation session than a surf.

The standout, if you can call it that, is that Tuesday the 8th afternoon pulse. It’s the only time the swell gets over 5 ft. But with the wind blowing straight onshore, it’s going to be a real grinder. If you’re a seasoned charger and don’t mind a bit of a beatdown, that’s your window. The rest of the 16 days is full of tiny, inconsistent, and often cross-onshore slop. It’s a frustrating run, but the forecast can change quick around here. Keep your eyes peeled.

Rusty.
