The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Narrabeen-Alley Rights. This is a beach and sandbar set-up that’s exposed to the swell, and it’s a very consistent spot. The water temp is about average for the time of year, nothing unusual there.
We’ve got a bit of a slow start over the weekend. Sunday morning the 19th has some 7ft ENE swell with an 11-second period, but the wind is onshore from the southeast and the energy is strong (1098). It’s not looking clean, and the tide could be a problem. Sunday afternoon drops to 7ft, still onshore and messy.
Monday the 20th morning is where it starts to get interesting. We’ve got a 6ft ENE swell, 11-second period, with a light 3 mph westerly that’s cross-offshore. The conditions are clean, and the energy is still solid (792). That’s the standout of the forecast – the best window for a proper paddle. Monday afternoon turns more cross-shore with a NE breeze, so the morning is the pick.
Tuesday the 21st morning holds 5ft ENE swell, 10-second period, with a light northerly cross-offshore breeze. Clean conditions, but the energy drops to 433. It’s surfable, but not as punchy. By Tuesday afternoon, the wind swings NE and picks up to 12 mph, making it lumpy.
Wednesday the 22nd morning sees 4ft ENE swell, 9-second period, with a gentle westerly cross-offshore breeze. Clean but small. Wednesday afternoon goes glassy with an ENE breeze at 3 mph, and the swell is only 4ft. Very ordinary, but if you’re desperate for a glassy session, it’s there.
From Thursday the 23rd through to the end of the month, the swell drops away. Thursday morning has 3ft, Friday morning 2ft, and by Saturday the 25th we’re down to 1ft. The wind is clean offshore on a few mornings, but there’s just no energy. That’s a long gap of poor surf.
Then on Thursday the 30th of July, there’s a spike of 1ft SSE swell with an 18-second period, but the wind is a strong 22 mph WSW cross-offshore. The energy is 147, but it’s too small to be worthwhile. Friday the 31st afternoon sees a 8ft SSE swell roll in with a 13-second period, but the wind is a fresh 22 mph southerly cross-onshore, making it lumpy and messy. The energy is massive (2136), but the wind kills it. That’s one for the experts only, and even then, the conditions are poor.
The start of August brings more wind and rain. Sunday the 2nd morning has 7ft SSE swell with a fresh cross-shore breeze, and the energy is strong (1127), but the wind is messy. No standout there.
Overall, the best bet is Monday the 20th morning. Clean 6ft ENE swell with a light offshore wind and solid energy. That’s the one to aim for. The rest of the window is either small, windy, or both.
Rusty.

Information about the Narrabeen-Alley Rights Surf forecast
