Narrabeen-South Surf Forecast and Surf Report

Hey, Rusty here again. Let’s talk Narrabeen-South in feet and knots for the next couple weeks. It’s a bit of a mixed bag, but there’s some proper juice if you’re patient.

Starting Friday the 31st of July, we’ve got a solid 6ft south swell with a 10-second period and a clean 20 km/h offshore from the SSW. Water’s 18° – about average for the season. Combined energy is moderate (687). This is good, clean surf – the south swell has some grunt, and that offshore wind will keep the walls tidy. This is the highlight of the early stretch. It’s an exposed beach break, and at 6ft it’s gettin’ proper – not a beginner wave. Crowds are often here, so don’t expect a solo session.

Friday afternoon stays clean at 7ft from the south but wind shifts cross-offshore. Still fine. Saturday the 1st of August brings a smaller 5–5ft SSE swell with glassy wind in the arvo – nice but nothin’ special. Sunday the 2nd sees a 5ft long-period (13 seconds) SSE groundswell, but the wind’s cross-on in the morning then onshore later. That long period at a beach break can get straight and tricky – combined energy is strong (999) but the wind ruins it. Monday and Tuesday the 3rd and 4th are flat – tiny dribbles under 3ft, not worth the walk.

Wednesday the 5th shows signs of life. Afternoon has a clean 5ft south swell with a gentle offshore wind – combined energy moderate (419). A reasonable option if you need a paddle. Thursday the 6th is the next proper standout: morning runs 6ft from the south with clean offshore wind (500 energy), afternoon pushes to 6ft from the south (678 energy, clean). Very good surf again – this is the other top pick. South swell, moderate energy, offshore breeze – the banks should be workin’.

Friday the 7th drops to 5ft with clean offshore in the morning, but the period shortens to 8 seconds, makin’ it a bit bumpy underneath. Saturday the 8th and Sunday the 9th go flat – under 3ft with messy wind. There’s a few days gap with nothin’ worth mentionin’. Monday the 10th is junk.

Now look ahead – Tuesday the 11th of August. This one’s got serious weight. Morning shows 7ft from the south at 9 seconds with a fresh offshore cross-off from the WNW. Combined energy is strong (1347). That’s a heap of water – 7ft on a beach break is expert-only. Afternoon holds 7ft from the south at 11 seconds (energy 1011), still cross-off wind. The longer period brings better shape but longer lulls. This is promising but it’s over a week out – stay tuned.

Wednesday the 12th drops to 4ft with clean wind, moderate energy. Thursday the 13th arvo has a sweet 3ft easterly groundswell at 11 seconds with a clean moderate offshore – ideal for a longboard if the sand’s good. Friday the 14th and Saturday the 15th stay small, with the 15th offerin’ a glassy 3ft easterly in the morning.

Bottom line: the best waves are Friday the 31st of July and Thursday the 6th of August – solid swell, clean offshores, moderate energy. That big Tuesday the 11th pulse is the one to watch if you’re experienced and keen, but it’s a long-range guess. For the rest, it’s lean. This beach doesn’t stay flat forever, so keep your board close.

Rusty.
