Table - best surf conditions forecast for Narrabeen-Alley Rights over the next 16 days.
Alright, Rusty here. Let’s have a look at what’s shaping up for the next couple of weeks. We’ve got a small window of genuine fun, then a long stretch of flat and blown-out nothingness.
The only spot on the cards is Narrabeen-Alley Rights, a beach/sandbar setup that usually handles a decent swell. Water temp is about average for this time of year, nothing weird there.
We start off a bit average. Thursday morning, 9th July, there’s a 6ft SE swell pushing in, but the wind is a light cross-shore, and the whole thing feels a bit marginal with questionable tide conditions. Combined energy is moderate at 826. Afternoon stays similar, just with a light cross-onshore breeze. Not worth getting wet for.
Friday 10th July is where it gets interesting. Morning sees a 6ft SE swell with a cross-offshore wind from the WSW – that’s clean, and the energy is solid (554). The afternoon turns glassy, with a 6ft SE swell and an ESE breeze so light it’s almost not there. That’s the standout of this whole run. Clean, lined-up, and a decent 10-second period – real surfable waves. This is the one to aim for.
Saturday 11th July drops a little in size – 3ft ESE swell – but the period stretches to 12 seconds, giving it some push. Morning has clean offshore wind from the NW, afternoon turns to a cross-off from the N. Crowds are likely here, so get in early. It’ll be fun but not as good as Friday.
From Sunday 12th July onward, it’s a slow death. Swell drops hard to 2ft and 1ft, then basically flat from Monday 13th through to the end of the forecast. There’s a nasty spell from Wednesday 15th July with strong winds and no waves, and a brief spike on Thursday 16th July afternoon with an 8ft SSE swell – but the wind is a near gale cross-onshore, so that’s blown to pieces and only for the lunatics. After that, it’s tiny leftovers with onshore breeze right up to Friday 24th July.
So the takeaway? Friday 10th July afternoon is the absolute best – glassy, clean, and a fun 6ft SE swell. Saturday morning is a decent backup but smaller. Then we’re looking at two full weeks of flat and windy rubbish. A real shame, but that’s winter for you.
Rusty.
