The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer over the next couple of weeks. We're talking about Narrabeen-Alley Rights, a solid beach and sandbar setup that's known for being very consistent and exposed to ENE swell. Right now, it's a pretty bleak picture, but there are a couple of windows that could be worth a paddle.
The water is sitting at 64°, which is about average for this time of year, so nothing unusual to worry about in terms of a wetsuit.
The next few days are a write-off. We're looking at a long gap of poor conditions from Tuesday the 21st right through to the end of the month. The wind is all over the place or non-existent swell. It's a flat spell, and the energy readings are down in the dirt, with values like 13 and 9. Not worth getting wet for.
Now, we finally get a bit of life on the 3rd of August, Monday morning. A clean cross-off breeze from the NNW and a 3ft SSE swell coming in at 10 seconds. The combined energy is moderate at 184. It's surfable, but honestly, it's nothing to write home about. The wind is just a slight air, so it'll be clean, but the swell is a bit ordinary.
The standout period, and the only one I'd really get excited about, is Tuesday the 4th of August. The morning is looking magic. We've got a gentle offshore breeze from the NNW and a 3ft SSE swell, but the period bumps up to 11 seconds, giving it a bit more grunt. The energy is strong at 246. The wind turns a bit more moderate offshore in the afternoon, with the swell holding at 3ft. This is the cleanest, most powerful window in the whole run. For a beach break, that longer period will mean some waiting between sets, but the shape and energy should be there. It's a solid choice for the advanced crew that calls this place home, and it's often crowded, so expect some company.
Wednesday the 5th of August gets blown out by a strong 19 mph cross-off shore wind, so it's a no-go despite the swell.
So, to wrap it up: there's a lot of flat and rubbish to sit through, but lock in the morning of Tuesday the 4th of August. That's your best bet. It's a few weeks out, but the forecast is promising.
Rusty.
