Nanarup Beach Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of swell on the cards for Nanarup Beach, but the wind’s gonna be the talk of the town. This is a consistent spot for a beginner, so don’t expect perfection, but there’s some absolute gems in the mix if you’re patient.

The water is sitting at 65°F — a touch warmer than normal for this time of year, which is a nice little bonus. The swell’s mostly from the SSW, which is almost its optimum, and the period is long, hovering around 15 to 17 seconds — classic groundswell. That long period means better-shaped waves with more energy, but at a beach break like this, it might break a little too straight, so keep that in mind if you’re chasing a wall.

The opening Sunday morning (9th August) is a tough one. There’s a massive 13ft SSW swell with a seriously strong combined energy of 16150 — that’s proper heavy. But the wind’s howling from the SW at 19 mph, cross-shore, making it lumpy and messy. The wave comment outright says marginal. Not the day.

Sunday arvo the swell drops to 10ft, but it’s still clean with cross-off wind from the W at 12 mph — a step up, but nothing to write home about.

Monday (10th) is a write-off. Strong winds and messy conditions, especially the arvo with that 12ft swell and cross-shore wind at 25 mph — that’s kite-surfing territory, not paddle.

Tuesday (11th) sees a return of that 13ft swell, combined energy of 9165 (strong), but again cross-shore wind at 19 mph keeps it lumpy. Still, for an experienced beginner who can handle size, there’ll be waves.

Now, here’s the standout. Thursday morning, 13th August. The swell eases to 10ft from the SSW, combined energy of 4234 (moderate), but the wind is a gentle WNW breeze at 9 mph, cross-off, and the conditions are clean. The wave comment calls it *excellent surf conditions for experienced surfers*. That’s your pick of the first week.

Come Friday morning (14th), the swell drops to 8ft, period still long at 16 seconds, combined energy 2794, and the wind is light from the NE at 6 mph, cross-off, with clean conditions. Another excellent window, especially if you want a bit less size.

The swell fades over the weekend, with 5ft on Saturday (15th), and 4ft in the arvo — clean but small. Then Sunday (16th) picks up again to 5ft with offshore N winds at 16 mph, making for very good, clean surf. That’s a sneaky good session for the lighter crowd.

And then, Monday morning 17th August — the real long-range highlight. The swell is 7ft from the SSW, period stretching to 18 seconds (very long period), combined energy of 3019, and the wind is a near-calm NW at 3 mph, cross-off, with clean conditions. Excellent surf for experienced surfers. That is a glassy, clean, long-period groundswell at a spot that rarely gets it this tidy.

The arvo that same Monday (17th) is even glassier — SSE wind at 3 mph, glassy conditions, 8ft SSW swell. Absolutely pristine.

The following days continue to offer solid 7ft to 8ft swells with offshore winds (N to NNW) through Tuesday (18th) and into the Thursday arvo (20th), which is clean with a gentle breeze. That whole stretch from the 17th to the 20th is your best run of the whole outlook.

The last few days (21st to 24th) wind back a bit with more cross-off winds and a bit of rain, but the swell holds around 7ft to 8ft. The final Monday (24th) finishes strong: 8ft southerly swell, offshore NNW wind at 6 mph, clean — a nice close to the window.

So, truth be told, the first few days are messy with big energy and cross-shore wind. Wait for Thursday morning 13th, or better yet, pin the 17th and 18th for the cleanest, glassiest conditions. That’s where the magic is.

Rusty.
