The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the next couple of weeks.
Alright, we've got a solid pulse of ENE swell lighting up Narrabeen-Alley Rights come Monday the 20th of July. The water's sitting at 64.6°, which is bang on average for the time of year, so no shock to the system there. This is a beach/sandbar setup, and it's very consistent, so it's a reliable spot to bank on. The real standout is Monday morning. We've got a clean 6.2ft of ENE ground swell rolling in with a period of 11 seconds, and a glassy 3 mph W wind. The energy is sitting at a solid moderate 832, so there's plenty of push. This is the pick of the entire forecast – expect very good surf conditions. The break is exposed to the swell, and that ENE direction is just what it wants. Keep in mind, it's an advanced wave, and crowds are often here, so expect some company. By Monday afternoon, that NE wind picks up to 9 mph and goes cross, making it a bit of a mess with a marginal tide.
Tuesday the 21st, the swell drops to 4.9ft, still with a decent 10-second period, and a light N wind gives us clean cross-off conditions in the morning. The energy's down to 433, still moderate. It's surfable and good, but not the standout Monday was. Tuesday arvo it gets messy again with that NE cross-shore.
Wednesday the 22nd offers a couple of clean windows. The morning has that same ENE swell around 3.6ft with a 10-second period, and a light W cross-off wind. The arvo turns glassy with a NNE breeze at 3 mph, and the energy is a consistent 210. It's good, clean fun for the intermediate crowd.
Thursday the 23rd, the swell drops to 2.6ft and the energy falls to 96 – that's weak. The morning is clean with a cross-off W wind, but it's ordinary. By the arvo, a strong SW wind of 22 mph kicks up a lumpy cross-chop, and it's poor.
From Friday the 24th right through to the end of the forecast on the 4th of August, it's a long, flat run. The swell drops to tiny 1.3ft, then 1.0ft, and eventually to 0.3ft or even flat. The energy numbers are all in the single or low double digits – weak as water. There's a brief spike on the 29th of July with a 1.3ft SSE swell and a 20-second period, but it's accompanied by a 19 mph SSW cross-onshore wind and a lumpy 131 energy, so it's a mess. That long period is more for reefs or points, but the wind kills it. There's nothing worth paddling out for in that second week. It's a blank run, and for this area, that's not unusual when the swell windows close.
So, the absolute best bet is Monday morning the 20th of July at Narrabeen-Alley Rights. Get out there early for the glass and the 6.2ft groundswell.
