The Lowdown
G'day, it's Rusty here. Well, looking at the next 16 days for Narrabeen-Alley Rights, it's a real mixed bag. We've got a pretty quiet start, but there's some decent energy building for the second half of the first week and into the second week. Let's break it down.
The first few days are flat out poor. Thursday the 30th and Friday the 31st are barely showing anything, with tiny swell around 0.7ft. There's a bit of water movement but it's just not worth paddling out for. The combined swell energy is sitting at a measly 7, which is barely a bump.
We finally get some life on Saturday morning, the 1st of August. We're looking at a 5.2ft swell from the SSE with a 9-second period. The combined energy jumps right up to 493 (moderate). The wind is a light WSW cross-off, so it should be clean. Water temp is sitting at 65.1°F which is pretty average for this time of year, nothing weird going on there. It's not a standout, but it's a surfable wave.
Sunday the 2nd is where it gets good. The morning session is the pick of the first week. We've got a 5.9ft SSE groundswell with a long 12-second period and a light northerly cross-off wind. That combined energy is a healthy 993 (moderate to strong). This is clean, decent quality surf. For the advanced crew, this is your morning session.
Monday the 3rd holds some fun waves with a 3.3ft SE swell (11-second period) and a clean offshore NW wind at 12 mph. Combined energy at 247. It's not as big as Sunday but still fun.
Then things drop right off. Tuesday the 4th through to Saturday the 8th of August is largely a write-off. A few tiny pulses but nothing you'd want to get out of bed for. The swell energy plummets to as low as 15.
Now, the second week starts to show some promise again. Sunday the 9th of August morning sees a 4.9ft SSE swell with a clean light westerly cross-off. Combined energy at 494. But the real standout for the whole run is Monday the 10th of August morning. We're talking a 5.9ft SE groundswell with an 11-second period, light NNW offshore wind, and a combined energy reading of 758 (strong). This is clean, strong, and has some proper push to it. This is your best option by a long shot.
Tuesday the 11th and Wednesday the 12th of August also have some solid size, with 6.9ft to 7.9ft swells, but the period drops to 7-8 seconds, making it a bit more of a windswell. The wind stays clean and offshore on the mornings though. For the experts, Wednesday morning the 12th is a big call—7.9ft, 8-second swell from the SSE with a clean cross-off wind. Combined energy is 785. Bring your big board and your wits.
After that, it fades out quickly into tiny stuff again by the 14th. So, if you're keen, don't sleep on that Monday the 10th morning. That's the one.
