The Lowdown

G’day, I’m Rusty, and I’ve been looking at the charts for Narrabeen-Alley Rights. This is a sandbar setup, exposed to the swell, and it’s an advanced spot, so it’s not for the faint-hearted.

The first real action fires up on Tuesday morning, 21 July. The swell is coming from the ENE at 5ft, with a period of 10 seconds, and the combined energy is sitting at 433 (moderate wave energy). The wind is a light N at 6 mph, blowing cross-offshore, which is perfect. The water temp is about average for this time of year. This is the standout of the whole run – clean, punchy waves for the advanced crew. You’ll want to be out there early before the crowds arrive, because it’s often packed.

The good vibes carry through to Wednesday, 22 July. Morning sees a WNW cross-off breeze at 6 mph, with the swell dropping a touch to 4ft from the ENE, still a 10-second period, and energy at 269 (moderate). The afternoon is the real gem – glassy conditions with the wind shifting to ENE at just 3 mph. The swell is 4ft, ENE, and the energy is 210 (moderate). That’s a session you’ll be stoked on.

Thursday, 23 July, the swell drops to 3ft, and by Friday, 24 July, it’s fading fast down to 2ft. The energy is weak (41 and 28). The wind stays clean through the mornings, but the waves are too small to get excited about. Saturday, 25 July, and Sunday, 26 July, are effectively flat – 1.0ft to 2ft with very low energy (15 and 14). There’s a gap of about four days here with no real surf to recommend.

We get a bit of a pulse on Monday, 27 July, but it’s a tiny 0.3ft SSE swell with a ridiculous 17-second period – that’s a very long period groundswell, but there’s just no size. The energy is 13 (weak). It’s a no-go. Tuesday, 28 July, is a bit bigger at 2ft to 2ft, but the energy is still weak (47 and 66), and the wind is messy. Not worth paddling out.

The end of the forecast window gets interesting. On Monday, 3 August, morning we see a jump to 2ft from the SSE with a 18-second period and energy of 350 (moderate). The wind is a strong W at 16 mph, cross-offshore, so it’ll be clean. This is a long-period groundswell, which can be tricky on a beach break – it might break a bit straight – but for the advanced crew, it’s worth a look. The size is small, so it’s not a standout.

The real late highlight is on Wednesday, 5 August, morning. The swell comes up to 4ft from the SSE, 10-second period, with energy at 390 (moderate). The wind is a light WNW at 6 mph, offshore, and the conditions are clean. This is your second-best bet in the 16-day window – a promising session, but it’s a long way out, so keep an eye on it.

All in all, Tuesday morning, 21 July, is the one to circle. Get yourself down to Narrabeen-Alley Rights for a serious session.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-Alley Rights surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Narrabeen-Alley Rights may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
