The Lowdown

Alright, Rusty here, let’s get into it.

First off, it’s a bit of a slow burn for the next couple of weeks. We’ve got some small stuff coming through on Friday the 17th, but honestly, the conditions are pretty ordinary to start with. The real action starts to build from the weekend into next week, so don’t get too excited just yet.

Friday 17th July – Narrabeen-Alley Rights is showing a tiny 2ft easterly swell with a short 6 second period and weak energy (52). The morning is glassy with rain showers, making it surfable but very ordinary. The afternoon turns onshore and messy. Keep the board in the car.

Saturday 18th July – Swell builds to 4ft, but the wind is onshore from the SSE at 12 mph, ruining it. Poor surf all day. Energy is moderate (131-171) but the wind is a killer.

Sunday 19th July – This is where it gets interesting. Swell jumps to 8ft from the ENE with a 11 second period, and the energy is massive at 1223 – that’s strong to very strong. The morning is onshore from the SE (9 mph) though, so it’s marginal. The afternoon cleans up with clear skies and a light cross-onshore, but still questionable for quality. This is a big, powerful groundswell, but with the onshore wind, it’ll be a bit lumpy. Keep an eye on it.

Monday 20th July – This is the standout. The morning is glassy with a clean 6ft ENE swell at 10 seconds, energy at 698. The wind is light NW, so it’s absolutely glassy. This is your best bet for the entire forecast period. The water temp is 64°F, which is about normal for this time of year. The afternoon gets a bit choppy with a cross-shore from the NE, but the morning session is the one to chase.

Tuesday 21st July – Early morning looks solid. 5ft ENE swell, clean offshore wind from the N at 3 mph, and good energy (471). The afternoon turns onshore and messy again. Tuesday morning is a solid backup.

Wednesday 22nd July – Dropping a bit, 4ft ENE swell, but the morning is clean with a light cross-offshore from the NNW. Good for a fun session, but nothing special.

Thursday 23rd July – Swell drops to 3ft, but the wind is offshore from the WNW at 12 mph. The sets will be clean, but it’s small. Ordinary.

From Friday 24th July right through to the end of the period, the swell fades away to tiny 0.3ft to 1ft conditions. There’s a long gap of nothing worthwhile from the 24th until the end of the forecast. The energy drops to weak numbers, and the wind is mostly onshore or cross. There’s a brief moment on the 28th afternoon with a glassy 1ft south-east swell, but it’s barely surfable.

So, the only real standout is Monday morning, 20th July at Narrabeen-Alley Rights. The ENE swell at 6ft, with a 10 second period, glassy conditions, and moderate to strong energy (698) – that’s the one to set your alarm for. The Sunday afternoon isn’t bad either, but the wind is a factor.

It’s a classic winter pattern: a short burst of solid swell, then a long flat spell. Don’t hold your breath for the second week.

Rusty.

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.

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.
