The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Narrabeen-Alley Rights over the next couple of weeks.
Straight up, it’s a flat spell for the first few days. We’re looking at a gap from now until Monday the 7th of September with nothing worth paddling out for.
Come Monday morning, the 7th, it’s looking clean but small. We’ve got a 2ft swell from the SSE with a period of 10 seconds, and the wind is glassy – that’s a real treat for the soul. The water temp is sitting at 65°, which is about average for this time of year, so you won’t need the thickest rubber. The energy is weak, sitting at 69, but for a cheeky dawn session on a log or a funboard, this is about as good as it gets early on. Get it while it’s clean because the wind is going to swing around later.
Monday afternoon sees the swell bump up to 5ft from the SSE, but the E wind kicks in cross-on, making it choppy. Not great. The energy gets a moderate kick up to 391, but the quality is poor.
Tuesday the 8th has a morning of cross-on wind and tiny 0.7ft junk. By the afternoon, we get a 6ft SSE swell, but it’s with an onshore wind and a short period of 8 seconds, so it’s messy. Energy is moderate at 471, but the wind ruins it.
The rest of the first week and into the second is a real bummer. We’ve got days and days of poor surf – small, windy, or both. There’s a brief moment on Monday the 14th morning with a 2ft NE swell and a clean offshore wind from the WNW, but it’s only just surfable, nothing special.
For the whole 16-day window, there isn’t a single standout session. The best on offer, and it’s a modest pick, is Monday morning the 7th of September. The glassy conditions on that little 2ft SSE bump make it the cleanest, most inviting window for the easy-going surfer. If you’re a beginner, that tiny 2ft is just right, not too big at all. Just be aware that this break can get crowded – the file says it’s often busy, so keep an eye out for company.
Other than that, the second week is a write-off. Small swells, cross-off winds, and very ordinary conditions. Not a lot to get excited about.
Stay patient, keep the wax soft, and watch that forecast.
Rusty.
