Su Paulo Su Surf Forecast and Surf Report

G’day, I’m Rusty. I’m looking at Su Paulo Su – a reef setup for intermediate surfers. Right now and for a long spell, it’s pretty flat out there. From Sunday 23 August through to the end of that week, the waves are almost nonexistent. The combined swell energy is weak – in the 20s and 30s (35 on Sunday morning) – with swell heights barely hitting 2ft from the northwest and short periods around 6 seconds. Winds are messy, and the water temp is about average for this time of year. There’s no standout session in the first week – just poor surf and very ordinary days. That blank run stretches for several days with nothing worth paddling for.

By Sunday 30 August, there’s a tiny lift. Combined swell energy reaches 71, with 2-3ft from the northwest at 7 seconds. The morning has light cross-offshore wind, keeping it clean, but the description says “surfable but very ordinary.” You could get a few, but it’s nothing special. That pulse fades quickly, and the following days drop back to tiny, weak waves under 2ft and periods under 6 seconds, with combined energy in the 10–46 range.

Into early September, we get a bigger pulse. On Tuesday 1 September afternoon, 3-4ft from the northwest at 6 seconds and combined energy of 98 – still called poor surf. Wednesday 2 September morning brings 3ft from the northwest at 7 seconds, clean with offshore wind, and combined energy of 63. It’s “surfable but ordinary” – not a standout, but the best so far.

The real uptick comes on Thursday 3 September afternoon. Swell jumps to 5ft from the northwest at 6 seconds, combined energy hitting 203 – moderate energy is here. But the wind is onshore, making it messy, so it’s still poor surf. Friday 4 September morning has 4-5ft from the northwest at 7 seconds, combined energy of 231, with light cross-shore wind. The wave comment says “marginal.” It’s the most size you’ll see in the 16 days, but the short period and cross-shore wind stop it from being a true standout. Intermediates can handle it, but it’s not clean.

After that, it drops hard – Saturday and Sunday 5-6 September see the swell shrinking to 2-3ft and then less than 1ft, with fresh onshore winds ruining it, combined energy dropping to 10 or less. Monday 7 September is flat and glassy.

So, if you’re keen, the morning of Friday 4 September is the pick – 4-5ft northwest swell and moderate energy – but the wind isn’t perfect. The rest of the 16 days is mostly flat or weak. No real standouts here. The forecast can change, so don’t lose hope.

Rusty.
