The Lowdown
G’day, it’s Rusty here.
Look, I’m not going to sugarcoat it. The next couple of weeks are looking pretty bleak for a proper paddle at Narrabeen-Alley Rights. This is a beach/sandbar setup, and it’s exposed, so it needs a bit of size and direction to get going. Right now, we’re looking at a whole lot of small, weak surf. The first few days are basically a write-off. We’re talking ankle-biters in the 1ft to 2.3ft range. There’s no energy behind any of it, with the combined swell energy sitting down in the weak zone, like 27 to 81. The winds are mostly cross-off or light, so the surface will be clean, but there’s just nothing to ride. This stretch runs from Wednesday the 5th through to Saturday the 8th. It’s going to be a long, flat spell.
The only real pulse in the whole window shows up on Monday the 10th. The swell jumps to 5.9ft in the morning from the ENE, with a 9-second period. The energy reading jumps into the strong zone at 545, so there’s some real push behind it. The wind is a fresh cross-off from the WNW, which should keep it groomed. This is the standout, no question. But keep in mind, this is a beach break, and a 9-second period is a bit short and crumbly. It’s not going to be a classic, but it’s the only day with any real size. The afternoon drops off to 4.6ft, but the energy is still moderate at 314, and the wind stays cross-off. After that, it falls away again. The rest of the second week is a struggle, with nothing over 2.6ft and most of it in the 1ft to 2ft range, with poor surf conditions and weak energy. The weekend of the 15th and 16th has some onshore winds, which will chop up what little there is.
So, here’s the long and short of it: if you’re desperate, Monday the 10th is your window. Sizes are there, but it’s not for beginners. Anything over 5ft is pushing it for the less experienced. The week after that is a write-off. It’s a flat run, but this spot is very consistent, so it won’t stay this poor for long. Forecasts change, keep an eye on it.
