The Lowdown
G’day, Rusty here. I’ll be straight with you – the next week or so is gonna be a tough slog for surf at Narrabeen-Alley Rights. We’ve got a long dry spell before anything worth paddling out for shows up. Don’t expect much from now through to the end of July; the models are showing next to nothing on offer.
The first real whiff of something rideable comes right at the tail end, on the 1st of August. Even then, Saturday morning only delivers a tiny 2ft swell from the SSE, with clean conditions and a light breeze, but the energy is weak at (86) – it’s really just a dribbler for the desperate. After that, it’s back to flat or junk for the next couple of days.
Now, hold onto your board, because things finally kick off from Monday the 3rd of August. That morning we see a bit of life with a 4ft ESE swell, energy climbing to (104), though it’s still pretty average. The real standout window opens up on Tuesday the 4th of August. Tuesday morning has a clean 6ft ESE swell (345) with a light offshore from the NW – that’s a proper session. But the pick of the entire forecast is Tuesday afternoon: a solid 7ft ESE swell, period around 8 seconds, pushing a strong energy of (635). The wind goes light and variable, nearly glassy. That’s the one to aim for, but keep in mind at 7ft this is getting into expert territory – not one for the beginners.
Wednesday the 5th of August keeps the fun rolling with a 6ft ESE swell in the morning, and that afternoon turns glassy with a 5ft ESE swell and clean conditions. Thursday the 6th offers another very good call, especially the afternoon with a 5ft E swell and a longer 11 second period (548), plus clean offshore winds. After that, the second week sees smaller but still fun options, though the winds get a bit fresh and the consistency drops. The 9th of August morning has a 3ft E swell but a strong 35 km/h offshore wind will make it a battle.
Overall, there’s a long gap with no surf until the 1st of August, then a couple of days of average dribble before the real quality hits from the 4th to the 6th of August. Those afternoons on the 4th and 6th are your best bet. Water temp sits around 65° – about average for this time of year. Crowds are often a factor here, so expect company on the standout days. And the optimum swell direction for this spot is ENE, so the ESE and E swells we get in early August are a decent match. Keep your eyes peeled.
Rusty.
