The Lowdown
Alright mates, grab a coffee 'cause this one's a slow burn for the next bit. We're looking at a pretty quiet start for my stretch of sand, with a nice little window opening up around the start of August. After that, things get real big and real mean by the second weekend.
For this first run of days, starting the 26th of July through the end of the month, it's practically flat. You're looking at ankle-snappers, mostly under 1 ft from the east and south-east, with the wave energy barely ticking over – we're talking numbers like 6 and 14. Even with a bit of a breeze off the land, there's nothing to push you down the line. Water's sitting at a typical 64°F, so nothing unusual there.
We get a pulse on Saturday the 1st of August. A 6 ft SSE swell shows up, but the wind is messy from the same direction, making it scrappy. The energy climbs into the moderate zone (535), but it's not the kind of clean surf we're after.
Sunday the 2nd of August is your real window. That morning, we get a clean 5 ft SSE swell with a long 11-second period and a solid moderate energy level of 796. The wind is going to go dead calm – a glass-off off a WNW breeze. That means Narrabeen-Alley Rights is going to be as clean as a whistle. It's a beach and sandbar setup, so with that long period look for it to be a little walled, but the shape on the right banks will be beautiful. It's rated for advanced surfers, so bring your A-game. The water is an average 64°F. Just a heads-up, the crowds can be *often* here when it's like this, so be ready to share.
That good stretch carries into Monday the 3rd of August morning. The swell drops a touch to 4 ft from the SE, but we've got a light cross-offshore breeze from the NNW at just 6 mph, keeping things clean. The energy is still a solid 331. A great backup session for sure.
The middle of the week after that fades back to small, weak 2 ft to 3 ft east swell. By the end of the week, we've got onshore southerlies and flat spells again.
Then, hold onto your boards for the second weekend. On the 8th, 9th, and 10th of August, a proper swell train arrives. Saturday morning the 8th has a solid 8 ft SSE swell, but it's getting slammed by strong 16 mph S winds onshore. By Monday the 10th, the forecast is calling for a massive 10 ft to 12 ft ESE swell with a cross-shore wind. The wave energy is off the charts (2418 and 2926). The call is that it's going to be too large and powerful for this exposed beach break. Unless you're a seasoned charger on a step-up, or maybe towing in for kite surfing, you'll want to watch this one from the sand. The wind is favorable for a few hours, but the size is just overwhelming for paddle surfing.
So, bottom line: The best bet is Sunday the 2nd of August morning, with Monday the 3rd morning as a good clean follow-up. After that, we've got a lull, and then a huge, powerful, and choppy swell for the expert crew only.
Keep the rubber side down.
