Mainside Surf Forecast and Surf Report

Alright, Rusty here. Let’s get into it.

Well, I gotta be straight with you – it’s looking pretty grim out there for a while. We’ve got a real dry spell on the cards before anything worthwhile shows up. The first week or so is mostly flat or junk, so don’t be in a hurry.

The main break we’re looking at is Mainside, a reef setup that’s exposed and needs the right direction. The water’s sitting at a warm 84°, which is right where it should be for this time of year – nothing unusual there.

Right from Tuesday the 18th of August, it’s a no-go. Tiny swell, wind all over the place, and poor conditions. That flat, windy pattern drags on through the rest of that week and into the next. There’s a real big gap here – from the 18th all the way through the 25th of August, there’s just nothing worth paddling out for. A few days show a tiny bump, but the energy is weak, like that Wednesday the 26th morning showing only 94 (combined energy), and the swell is short-period at 5 seconds – that’s just wind chop.

Then things start to get interesting. Thursday the 27th of August morning, we see a proper groundswell arrive. It’s 12 ft from the east with a long 16-second period. That’s some serious energy – 7997 (combined energy). But here’s the catch: the wind is cross-shore, so it’ll be a bit bumpy and tricky. This is advanced territory for sure – over 8 ft means it’s experts only. The swell direction is east, and Mainside’s optimum is north, so it’s not the ideal angle. That said, a long-period east swell on a reef can still produce some heavy, grinding walls – just be ready for a battle getting out and some lumpy faces.

Friday the 28th of August morning is even bigger – 16 ft from the ENE – but it’s onshore and just messy. Not one for the average surfer. That’s a hard pass.

After that, we drop back into small, weak, and windy conditions right through the end of August and into the start of September. There’s a slight glimmer on Tuesday the 1st of September afternoon – 2 ft from the east, 13-second period, light offshore wind, energy of 186 (combined energy). It’s surfable, but it’s ordinary. Nothing to get excited about.

Now, the real standout is shaping up for Wednesday the 2nd of September morning. A big 20 ft west swell with a 12-second period, and the combined energy is massive at 9865 (combined energy). That’s a strong, powerful swell. But the wind is cross-shore again, and it’s going to be a bit chopped up. For an exposed reef like Mainside, that size is only for the absolute experts. The afternoon sees a similar size but with a stronger onshore cross-wind, so it gets lumpy and less appealing.

So, to wrap it up: the best bet in this whole 16-day window is the Thursday the 27th of August morning session at Mainside. It’s a big, long-period east swell with serious power, but the wind won’t be perfect, and it’s not the ideal direction for the break. The Wednesday the 2nd of September morning has the biggest swell of the period, but again, the conditions are rough. For the average surfer, there’s not much to chase here. If you’re an expert looking for a big, challenging reef wave, those two windows are your only real options.
