The Lowdown
G’day, it’s Rusty here.
Well, to be straight with you, the surf chart for Narrabeen-Alley Rights over the next couple of weeks is looking pretty grim. We’ve got a long stretch of tiny, junky waves ahead. You’d be hard-pressed to find anything rideable until around the 16th. That’s over a week of waiting, so if you’re keen, maybe dust off the longboard and the kite gear.
The water temp is sitting at 65°F, which is right about normal for this time of year. Not much to get excited about there.
Let’s run through the bleakness. Tuesday the 8th is a write-off – morning has a pitiful 0.7ft of east slop, and while the afternoon bumps to 7ft from the SSE, the period is a short 8 seconds and it’s cross-onshore. It’s all over the place. Wednesday the 9th through to Friday the 11th is just tiny, onshore junk, nothing over 2ft and most of it under 2ft. The energy numbers are mostly in the low double digits, which is just weak.
We get a day of offshore wind on Saturday the 12th, but the swell has died to 0.7ft. Clean and flat, that's about it. Sunday the 13th has a tiny 3ft pulse short-period, but it’s cross-shore. Monday the 14th also has a morning offshore, but again, only 2ft of weak, short-period swell. The 15th brings a bit more size in the afternoon, 5ft, but it’s cross-onshore and the period is only 6 seconds, so it’ll be a stormy mess.
Finally, we get something to talk about. Wednesday morning, the 16th of September. We’ve got 4ft of SSE swell with an 8-second period. The wind goes glassy, and that’s the standout window. The combined swell energy reads 222, which is moderate, and with the winds going dead calm, it will be clean. That’s your window. It’s not huge, but it’s the clear pick of the fortnight. The afternoon flattens out again though.
After that, it’s back to the doldrums. Thursday the 17th through the 22nd is all under 3ft, with short periods and cross-shore winds. Not worth the drive. There’s some offshore wind again on the 19th and 20th, but the swell is just 3ft with a 7-second period, which would be very ordinary.
The last possible glimmer is on Wednesday the 23rd of September. There’s a 4ft NE swell with clean offshore winds in the morning. The energy is moderate at 148, but again, the 6-second period kills it. It might be surfable, but you won’t be bragging about it.
So, there you have it. There's one morning – the 16th – that looks worth getting out of bed for. The rest? It’s a waiting game. This break doesn’t tend to stay flat forever, and a forecast can change, but you’d be mad to plan your life around it.
Stay patient.
Rusty.
