Narrabeen-Alley Rights Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s get into it.

First up, we’re looking at a classic Sydney stretch, Narrabeen-Alley Rights. It’s a beach and sandbar set-up, exposed to the swell, and it’s a very consistent spot. The water temperature is sitting at 64°, which is spot on for this time of year – nothing unusual there.

The outlook has a rough start. For the first week, from Sunday the 6th through to the 12th, it’s mostly a write-off. There are a few tiny pulses of swell, but the wind is a mess – cross-shore, cross-on, and choppy. Monday morning the 7th is glassy but with only 0.7ft of weak, short-period wind swell (energy of just 10). It’s not worth paddling out for. Tuesday afternoon on the 8th sees a bit more energy with a 7ft SSE swell (energy of 850), but the wind is onshore and the forecast is marginal. Honestly, it’s a long, quiet week with nothing to get excited about.

The real story starts Sunday the 13th. We get a clean-up crew. A light north-northeasterly breeze gives us a clean, cross-off wind, and the swell is a solid 4ft from the SSE with a decent 10-second period. The energy is moderate at 364. It’s not massive, but it’s clean, and that’s a winner after the dry spell. That Sunday morning is the standout of the first half.

Then Monday the 14th is even better. A moderate offshore wind from the NNW keeps it clean, with a 3ft groundswell from the SSE, 12-second period, and energy of 324. The afternoon session is similar, with a 3ft swell and 11-second period. If you can get out, Monday is the pick of the week.

Now, we’ve got a bit of a gap. Tuesday the 15th through to Friday the 18th is mostly poor again – small, weak, and choppy. Friday the 18th is a flat day with zero wave energy.

But hold onto your board, because the real action is on the weekend. Saturday the 19th September is the standout of the entire 16-day window. We’ve got a 8ft SSE groundswell rolling in with a 12-second period, pumping out a massive 2636 energy. The wind is light and cross-off from the WSW, making it clean. This is excellent surf, but that 8ft is serious – it’s for experienced surfers only. This is a proper, powerful groundswell. It’s a long-period swell, which means it’ll have longer gaps between sets, making paddling out easier, but at a beach break like this, it might break a bit straight on the banks. Still, this is the one to aim for.

Sunday the 20th is still pumping, with a 7ft SSE swell (energy of 1457) and a 13-second period, with light offshore winds again. Another fantastic morning for the advanced crew. The afternoon gets a bit messy with a cross-shore NE wind, so get in early.

By Monday the 21st, the swell is dropping and the onshore wind returns, so it’s back to choppy conditions.

The standout is undoubtedly Saturday the 19th. The combined energy is huge, the swell is solid, and the wind is perfect. For the advanced surfers, that’s the day. The Sunday the 13th and Monday the 14th are your best bets for cleaner, smaller waves if you’re not ready for the big stuff. If you’re a beginner, give the 19th and 20th a miss – the 8ft is too big for you.

Rusty out.
