The Lowdown
G’day, Rusty here. Let’s look at what’s on the cards for Narrabeen-Alley Rights over the next couple of weeks.
We start off flat. Friday the 31st has next to nothing – an easterly swell of about 0.3ft with weak energy (5 to 7). Wind is messy, so don’t bother. Saturday the 1st morning stays tiny and clean but still no real surf. Then Saturday afternoon a small pulse hits: around 5ft from the SSE, period 9 seconds, but wind is light cross-on and energy is moderate (410). It’s marginal.
Sunday the 2nd morning is the real highlight. The SSE swell holds at about 5ft, period stretches to 12 seconds – proper groundswell – and we get clean, glassy conditions with a light northerly cross-off breeze. Combined energy is strong at 887. This is the standout. The wave size is fine for most surfers, and with that longer period it’ll shape up nicely. Crowds are common here. Water temp is about average for this time of year. This is your best session.
Sunday afternoon the wind turns onshore from the NE at 12 mph, and quality drops. Monday the 3rd morning has a clean 3ft SE swell at 11 seconds (energy 255) – decent, but not as good as Sunday. After that, it fades. There’s a gap of poor conditions from Tuesday the 4th right through to Friday the 7th, with waves under 2ft and messy winds.
Saturday the 8th morning brings a return: 5ft SSE swell at 10 seconds, clean with light WSW cross-off wind (energy 486). It’s a solid option. Sunday the 9th morning is similar with 4ft SE at 10 seconds (309). Then Monday the 10th afternoon improves: 4ft ESE at 11 seconds, moderate offshore wind from NNW at 12 mph (energy 327). Clean and punchy.
After that, the long-range fades. Tuesday the 11th onward has waves mostly under 3ft, energy below 200. The last hopeful session is the morning of the 12th – 3ft ESE at 10 seconds (206) – but it’s weak. The final week, from the 13th of August onward, is all poor with onshore gales and messy surf.
Bottom line: Sunday the 2nd morning is the one to chase. Everything else is either small, windy, or a long shot.
Rusty.
