Supertubos Surf Forecast and Surf Report

G'day, Rusty here. Look, I'll be straight with you—this 16-day window for Supertubos is a bit of a mixed bag. We’ve got a slow start with some rough conditions, but there’s a real standout morning that’s worth getting excited about, even if it’s a bit of a wait. The rest of the forecast is mostly small and clean, but not the kind of juice that gets your heart pumping.

The water at Supertubos is sitting at 66°, which is a bit colder than normal for this time of year. The initial outlook is pretty grim. Tuesday the 25th and Wednesday the 26th are a write-off with poor surf, light to moderate onshore winds, and messy swell. Energy is weak, readings like 167 (Tuesday morning) and 103 (Wednesday morning) – not worth paddling out for. Thursday the 27th is bigger but still sloppy: around 7ft to 7ft from the west, with cross-onshore winds and lumpy conditions. The energy is moderate (466-479), but it’s just not clean.

Now, here’s the good news. Friday morning, the 28th of August, is the one to circle. The wind swings offshore from the NNE at a gentle 9 mph, and we’re looking at a solid 8ft west-northwest swell with a period of 11 seconds. That’s a proper groundswell, and the combined energy is pumping at 1267 – strong to very strong. The forecast says “expect very good surf conditions,” and I’m backing that. This is a standout morning for advanced surfers only, as it’s a bit too big for beginners. The offshore breeze will keep things clean and lined up at Supertubos, a beach and reef setup that handles this well. The swell direction is a touch off the optimum (SW), but the quality and power make up for it.

After that, the swell drops off quickly. Friday afternoon is smaller at 7ft, but the wind goes cross-offshore, making it clean but marginal. Saturday the 29th and Sunday the 30th are still clean but much smaller, around 3ft to 5ft, with light to moderate cross-off breezes. The energy is weak to moderate (302 down to 125). It’s surfable but ordinary.

Then we hit a major lull. From Monday the 31st of August through to Tuesday the 8th of September, wave heights are tiny, often 0.3ft, with energy readings as low as 3. This is a long gap of flat, clean conditions. There’s a brief glimmer on Wednesday the 2nd of September morning, with a 4ft northwest swell and clean conditions, but it’s nothing special. The rest of the period up to the 9th is mostly flat, with no real standouts. The last few days show a tiny pulse of 3ft to 4ft, but it’s weak and not worth chasing.

So, the best of the bunch is undoubtedly Friday morning, the 28th of August. Get out there early if you’re advanced and hungry for a clean, powerful session. The rest is a wait-and-see game.

Rusty.
