Big Rock Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for Big Rock over the next couple of weeks.

Honestly, it’s a bit of a grim stretch for this spot. We’re looking at a long, slow run of poor conditions. The water’s sitting at 72°, which is a touch warmer than normal for this time of year, so at least you won’t need a thick suit.

The opening day, Saturday the 5th of September afternoon, is a write-off. There’s a cross-onshore breeze messing up a 4ft southerly swell. The combined swell energy is high at 1117, but with that wind, it’s just choppy and ugly. The next couple of days don’t get much better. Sunday the 6th sees a little more size, pushing 6ft from the SSW, but that moderate cross-shore wind is tearing it up. The energy spikes to 1555 on Sunday afternoon, but it's a total mess.

We do get a bit of a breather on Wednesday the 9th of September morning. The wind swings to a light WSW offshore, and there’s a tiny 2ft swell from the SW with a super long 16-second period. That’s a proper groundswell, but there’s barely any push behind it – the energy is only 384. It’s marginal at best, and the lack of size means it’s really only for a longboard with no expectations. The long period will make the waves a bit tricky and walled-up at a reef like this, and only for the skilled.

The rest of that week and into the second week is just more of the same: small, weak, and mostly cross-onshore winds. There’s a brief flicker on Monday the 14th of September morning with a 4ft westerly swell and an offshore wind, but the period is a short 8 seconds and the energy is only 400. It’s still rated as poor. By Saturday the 19th of September morning, we see a bit more size bumping up to 5ft from the west with an offshore breeze, and the energy is 637. That’s the best-looking window in the whole 16 days, but it’s a long way out and the wind forecast is still uncertain. For now, it’s a promise, not a guarantee.

Look, if you're desperate, that Wednesday the 9th morning and that distant Saturday the 19th morning are the only real windows. Big Rock is a reef that needs a clean swell to shine, and we just aren’t getting that. For most of this run, it's more of a kiteboarding setup than a paddle session.

Rusty.
