North wall Surf Forecast and Surf Report

G’day, Rusty here. Let’s break down what Northwall has in store for the next couple of weeks.

We’re starting with a big pulse on Thursday, 10 September. The swell is a solid 12 ft from the SSE with a 9-second period, pushing a combined energy of 1792 (moderate to strong). That’s a lot of power. For a beach/groyne/river setup that’s beginner-friendly, 12 ft is way too big – it’s an expert-only affair. The wind is a fresh 35 km/h from the south, cross-offshore, so the face will be clean, but the size is the story. Thursday afternoon drops to 10 ft from the SSE, still too big and messy with a cross-shore wind. The water temp is 69°F, which is about average for this time of year.

The real standout, and the session I’d be most excited about, is Sunday morning, 13 September. The swell is a much more manageable 5 ft from the SSE, but the period stretches to 11 seconds – that’s a proper groundswell with good shape and energy. The combined energy is 861 (moderate). The wind is glassy, dead calm, zero. That’s pure magic for clean, peeling waves. The tide conditions are expected to be very good, so it’s the pick of the window. It’s beginner-friendly in size, but with that long period, it’ll have some punch and longer lulls, making paddle-outs easier. Crowds are “sometimes” an issue, but for conditions this perfect, it’s worth the company.

Saturday morning, 12 September, offers a 6 ft SSE swell, but with a gentle cross-onshore breeze, it’s a marginal day. Not a write-off, but not the star. Monday morning, 14 September, has a tiny 3 ft from the SSE with glassy winds again, but it’s very small and ordinary.

After that, the surf goes flat for a long stretch. From Tuesday, 15 September, through the rest of the first week and into the second, the swell drops to knee-waist high, the wind turns onshore or cross-onshore, and conditions are poor. There’s a long gap of choppy, messy, or tiny surf. Saturday, 19 September, sees a bump to 7 ft from the SSE, but the wind is a moderate 25 km/h cross-offshore, and the quality is marginal – maybe a look if you’re keen, but not a standout.

Looking into the second week, Thursday, 24 September, has another big swell: 10 ft from the south with an 11-second period and a massive combined energy of 3763 (strong to very strong). The wind is offshore from the WSW, so it’ll be clean, but 10 ft is expert territory only at this break. The afternoon drops to 8 ft but with a strong cross-offshore wind. It’s a promising but distant call for the experienced crew.

The best on offer is Sunday morning, 13 September – that glassy 5 ft groundswell is the gem. The rest of the window is mostly small, windy, or too big for the average surfer. Keep an eye on that 24 September pulse if you’re an expert, but it’s a long way off.
