Narrabeen-South Surf Forecast and Surf Report

Righto, let’s have a look at what’s coming up. This stretch is all about one spot: Narrabeen-South. It’s an exposed beach break that handles a decent south-east swell, but the size and wind are gonna be the big talking points.

The forecast kicks off on Monday 6 July with a solid pulse. The swell is a chunky 10 ft from the SSE, with a period of 10 seconds, and the combined energy is serious – sitting at 1775 (moderate to strong). That’s meaty, overhead-plus stuff, and the cross-off wind from the SSE is keeping things reasonably clean. But honestly, for most of us, this is too big. 10 ft at Narrabeen-South is only for the advanced crew. It’s a powerful, heavy wave. The water temp is 65°, which is pretty much average for this time of year. Monday afternoon stays similar. Tuesday 7 July brings more of the same – morning sees 10 ft SSE with a clean offshore SSW wind, pushing the energy up to 2477. Tuesday afternoon gets even bigger: 12 ft from the SE, period 11 seconds, energy 2771. This is big, powerful groundswell, and again, expert-only territory. Wednesday 8 July sees it drop a bit to 8 ft from the SE, but the wind gets messy – cross-off and fresh – making it a marginal call. The energy is still high (1818 morning, 1611 afternoon). Thursday 9 July is where it starts to get interesting for the average punter. The swell drops to a much more manageable 7 ft from the SE, with a 10-second period. The morning has a light offshore SSW breeze, dropping the energy to 866 – moderate. That’s a sweet spot. Clean, solid, and punchy. The morning is the standout window here. Friday 10 July keeps it clean and fun: 6 ft to 6 ft SE swell, with light offshore winds and clean conditions. Energy drops to 683 then 580. Really nice, consistent, head-high surf. This is the best of the first week. The crowds are a thing here though – Narrabeen-South is often packed when it’s good, so expect company.

Then we hit a flat spell. Saturday 11 July is poor – small and onshore, with only 4 ft to 4 ft of weak, short-period junk. Sunday 12 and Monday 13 July are dead: combined energy drops to 212, then 120, then a pathetic 8. Tiny, weak, not worth paddling out. That gap stretches through to the end of the week. The only flicker is Tuesday 14 July when a new S swell comes in at 5 ft, period 10 seconds, with a light offshore WNW wind. Energy is 415 – moderate. It’s surfable but nothing special. Wednesday 15 July is average, and Thursday 16 July sees the south swell build again – 8 ft to 8 ft, but with a fresh cross-off SSW wind making it lumpy. Energy climbs from 672 to 1386. Not the best.

Now, here’s the real standout – and it’s a long way out, so treat it as promising but not locked in. On Friday 17 July, a massive S swell arrives: 17 ft with a 13-second period, and the energy is a colossal 15243 (very strong). That’s huge, heavy, and for experts only. The wind is cross-off from the SSE, so it’ll be clean. But 17 ft at a beach break like Narrabeen-South is dangerous. It’s going to be straight, powerful, and intimidating. The afternoon drops to 12 ft, still huge. Saturday 18 July offers a glimmer for the brave: the swell drops to 7 ft from the SSE, period 9 seconds, and that morning? Glassy. Dead calm wind, light offshore from the W. Energy is 645. That’s the pick of the second week for anyone who’s skilled – clean, solid, overhead waves with no wind. But it’s a Saturday, so crowds are likely. After that, Sunday 19 July is onshore and small, and the rest of the period fades into weak, short-period leftovers. There’s a small glimmer on Tuesday 21 July – 5 ft from the south with a very long period of 19 seconds (energy 501), but that kind of period at a beach break can be weirdly straight and hard to line up. It’s more of a novelty.

So overall, the best windows are Thursday 9 and Friday 10 July – clean, head-high, consistent surf for competent surfers. The Saturday 18 July morning is the second-week wildcard: glassy and a bit smaller, but still solid. Everything else is either too big, too small, or too messy. This stretch throws a lot of power at us, then goes quiet. Keep your eyes on those two days.
