Rosa Surf Forecast and Surf Report

G’day, this is Rusty.

Alright, let’s have a look at the next couple of weeks at Rosa. The pattern starts off a bit slow, with some small, short-period swell and mixed wind, but there is definitely a run of cleaner, bigger surf coming mid-week and into the following week. The main standout window sits around the 5th to the 7th of September, but hold your horses—the swell gets seriously big, so that one is for the experienced crew only.

Starting this Saturday afternoon (29 August): We’ve got a 5ft swell coming from ENE with a period of only 8 seconds, so it’s pretty average. The wind is a cross-off from the SSW at 9 mph, which keeps it clean, but the wave energy feels moderate at best (276). It’s rideable but nothing to get too excited about. The water temp is sitting at 66°, which is bang on average for this time of year—no surprises there.

Sunday morning (30 August) looks nicer for a paddle. The swell drops a touch to 4ft from the ENE, still short period at 8 seconds, but the wind goes totally glassy—NNE at 0 mph. That means smooth, clean conditions. Energy is moderate (203). It’s a pretty mellow session, good for a few cruisy ones.

Monday (31 August) turns a bit ugly. The wind picks up from the NE at 12 mph, cross-on, and the swell jumps to 7ft from the E with only 8 seconds. That’s a messy, choppy combo with strong energy (581). Not worth the paddle.

Tuesday morning (1 September) brings a slight improvement. Swell drops back to 5ft from the ESE (8 seconds), and we get a cross-off from the SW at 6 mph. Cleaner, moderate energy (358). It’s a solid session for intermediates.

Now here’s where it gets interesting. Wednesday morning (2 September): We see a jump in swell to 8ft from the S with a period of 9 seconds. The wind is cross-off from the SW at 9 mph, and the wave energy is strong (1143). This is a bigger, more powerful wave, but still clean. It borders on being too much for beginners, but for the intermediate crew, it’s a real treat.

Thursday and Friday (3-4 September) fade out fast. Swell drops and the wind turns cross-on and onshore, really choppy. Not your best days.

The big standout is Saturday 5 September morning. We’ve got a 8ft swell from the S (8 seconds) with cross-off SW wind at 9 mph—clean and punchy. Energy is strong (887). The surf is very good, and it’s manageable for strong intermediates. But Saturday afternoon is the real eye-opener: the swell jumps to 10ft from the S with a 10-second period. Wind is cross-off from the SW at 12 mph, and the combined energy rockets up to 1917. That’s a big, powerful swell. It’s predicted to be too big for this break, meaning only expert surfers should even think about it.

Sunday 6 September is also pure big-wave territory: 12ft and 10ft swells from the S, periods of 12 seconds, and massive energy readings of 5211 and 4612. The wind stays cross-off, so it’s clean, but this is expert-only stuff. Too big for the average punter.

Monday 7 September morning is a bit of a reset: the swell drops to 6ft from the S (11 seconds, nice long period), with glassy SW wind at 3 mph. That’s clean, lined-up, and the energy is still strong (869). This is a very good session for solid intermediates—long period groundswell making its way in, so expect some nice open faces at the point.

Tuesday and Wednesday (8-9 September) see the swell holding around 5ft to 7ft from the SSE with long periods (13-14 seconds), but the wind turns cross-on and onshore from the NE, making it choppy. The energy is high (1296-1970), but the surface gets messy. Not the pick.

Thursday 10 September afternoon is a dark horse. The wind goes glassy (SE at 0 mph), and there’s a 6ft swell from the SSE with a 12-second period. Energy is moderate-high (945). That’s clean, glassy, and very surfable—a sneaky good session.

The final weekend (12-13 September) fades out. Saturday morning is glassy (NNW 0 mph) but the swell is only 4ft from the SE (11 seconds), energy moderate (419). It’s clean but small. Sunday goes downhill with onshore wind and rising swell from the ENE, not good.

So, the best bets: For the everyday surfer, Wednesday morning 2 September is a clean, punchy 8ft S swell—just watch the size if you’re a beginner. The absolute standout for the whole period is Monday morning 7 September: 6ft S swell, 11-second period, glassy as a mirror. That’s the one to circle on the calendar.

Signing off, Rusty.
