Rosa Surf Forecast and Surf Report

G’day, I’m Rusty, and here’s how things are shaping up at Rosa. It’s a bit of a slow burn to start, with a whole lot of nothing much going on right through the end of August and into the first few days of September. The swell’s there but the winds are just messy – cross-onshore and lumpy, so you’re not missing a thing. Honestly, it’s a bit of a flat spell for any decent paddle surfing for the first week.

The real standout, the one you need to circle on the calendar, is Tuesday morning, 2nd September at Rosa. The water’s sitting at 64°, which is actually pretty normal for this time of year – just a touch under the long-term average, nothing wild. That morning you’ve got a solid 8ft southerly groundswell, with a period of 11 seconds packing a punch – combined wave energy of 1,468 (strong). And get this: glassy conditions. Zero wind. That’s the kind of morning where it’s just you and the ocean. The swell direction from the south is right in the sweet spot for this break, and the size means it’s definitely for experienced surfers only – over 8ft is expert territory. The crowds are only “sometimes” an issue, so you’ve got a good chance of a uncrowded peak.

Now, heading into Wednesday 3rd September, the Thursday morning session (3rd) is worth an early alarm. You’ve got a clean 6ft south swell, period of 10 seconds, with light offshore winds from the southwest. Wave energy is moderate at 673. It’s a solid, good-quality option without the wild size of the Tuesday.

After that, things drop right off again. From Friday 4th September right through to Tuesday 8th September, it’s a real run of poor surf conditions – cross-on winds, short-period slop, and choppy water. The swell is there but it’s not doing anyone any favours. Paddling out would just be frustrating.

Then, on Wednesday morning 9th September, another little burst shows up. A clean 7ft south-southwest swell, period of 8 seconds, with light cross-offshore winds. Wave energy is moderate at 648. This is a solid pick for intermediate surfers – it’s not huge, but it’s clean and rideable.

Through the rest of the second week, the 10th and 11th of September look marginal – some size but the winds are onshore or cross-shore, keeping things choppy. Nothing to get excited about.

So the top call is crystal clear: Tuesday 2nd September morning at Rosa – glassy, powerful, clean. That’s the one.

Rusty.
