The Lowdown
Righto, Rusty here, taking a look at what’s on the cards for the next couple of weeks. It’s a mixed bag, but there’s a real standout session that’ll get the blood pumping.
First up, we’ve got Narrabeen-Alley Rights. The water’s sitting at 64°, which is bang on normal for this time of year—nothing weird there.
The week kicks off proper on Saturday, August 1st. It’s nothing special, but you’ll get a clean 5 ft swell from the SSE with a light cross-off wind from the west at 6 mph. The wave energy is moderate (450). It’s a start.
But the real gem is Sunday, August 2nd – morning. This is the standout. A solid 5 ft swell from the SSE, but it’s packing a 13-second period, meaning proper groundswell energy. The combined energy is pushing strong (1012), and a light northerly cross-off at 6 mph will keep it glassy. The wave comment says it’s excellent for experienced surfers, and that’s fair—this is a long-period swell, so it’ll wrap in nicely and hold its shape. It’s an advanced break, so leave the beginners on the beach. Crowds can be common here, so get in early.
Monday, August 3rd morning, is a decent follow-up. The swell drops to 3 ft from the SE, but a 9 mph offshore from the NW is blowing straight into the face, keeping it clean. Energy is moderate (248). It’s a good, mellow session.
Then things go quiet. From Tuesday, August 4th, right through to Saturday, August 15th, we’re in a dry spell. Wave heights drop below 3 ft, periods are short, and the energy is weak. There’s a lot of days with nothing to get excited about—just small, weak waves and poor conditions.
Finally, on Sunday, August 16th – morning, there’s a flicker of life. A 2 ft SSE swell, but with a massive 18-second period and strong energy (640). It’s a long-period groundswell, which is great for this point, but the cross-on wind from the east at 6 mph will put a bit of a wrinkle on it. The wave comment says it’s marginal, so it’s not a lock, but worth a look if you’re desperate.
For the hardcore, Sunday morning session on August 2nd is the only true standout. Make the most of it.
Rusty.
