The Lowdown

Alright, Rusty here, let’s break down what’s coming for Narrabeen-Alley Rights.

Water’s sitting at 63°, which is a bit chillier than usual for this time of year, so don’t forget a wetsuit.

Right now and for the next week, it’s a tough stretch. Tuesday afternoon there’s a tiny 2ft ENE swell but the energy is weak (78), and conditions are just ordinary.

Wednesday through Saturday this week is dead – wave heights drop to 1ft or 2ft, winds are onshore or cross-onshore from the south and east, and the combined energy barely gets above 50. Choppy, messy, not worth the paddle out.

Sunday the 16th stays poor – super short period 5-second windswell, onshore wind, rain. No go.

Monday 17th and Tuesday 18th see a jump in size to around 5ft, but it’s all short period windswell from the east-southeast with cross-onshore winds. Energy climbs into the 200s but the quality is poor – chop and rain. More of a kite day.

Wednesday 19th is more of the same – 5ft waves, onshore wind, poor.

Thursday 20th August things change. Swell hits 8ft from the east, period up to 9 seconds, and energy jumps into the 900s. Winds go light but still onshore or cross-onshore. This is expert-only size, especially with the wind angle.

Friday 21st August keeps a solid 7ft east swell. Morning has a light cross-shore wind from the southwest that might clean it up a bit, but the afternoon turns onshore again.

The standout is Saturday 23rd August morning. We’ve got a 5ft east-northeast groundswell with a 10-second period, light north wind giving cross-offshore conditions, and energy at 441 – solid, clean, well-shaped. The rights will be running. Crowds are often here, so get there early.

Sunday 24th August morning is another good call – 4ft ENE groundswell, 10-second period, clean north cross-offshore wind, energy 319.

Tuesday 25th August morning is a nice little session too – 4ft ENE swell, north-northwest offshore wind, clean, energy 254.

Wednesday 26th August morning keeps it going – 4ft ENE swell, light north cross-offshore wind, clean.

So bottom line: a long flat spell now through mid-next week, then the swell comes up but with messy wind until Saturday 23rd August morning – that’s the clear winner. The week after has a few more clean mornings worth chasing.

Rusty out.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
