The Lowdown
G’day, Rusty here. Look, I’ll level with you – the first week and a half of this forecast is a bit of a write-off for Right and Left Side, a reef break that’s exposed to the north. The water’s sitting at a warm 85°F, which is pretty normal for this time of year, so no surprises there.
The first solid surf we can actually talk about shows up on Sunday the 13th of September. It’s a small rebuild, but the conditions are what make it worth a mention. We’re looking at a clean 3ft swell from the ENE, with a period of 13 seconds that’s got some decent energy behind it (370). The wind is light offshore from the SSE, which will keep the faces crisp. It’s a long period groundswell, so on a reef like this, it should wrap in nicely. The catch is, this spot is inconsistent and it’s an advanced wave, so it’s not for everyone. Plus, it can get crowded sometimes.
The standout run starts Monday the 14th with more of the same: clean 2ft waves from the ENE, gentle offshore winds, and a solid 11-second period. The energy is moderate (229). Tuesday the 15th picks up a touch, with a 3ft ENE swell and a 13-second period, making for some punchy, clean waves (313 energy). But the absolute best on offer is Wednesday the 16th of September morning. The wind goes glassy, dead flat, from the ENE, with a 3ft swell and a 13-second period. Those conditions are about as perfect as it gets for a reef break, with clean, peeling lines. The energy is solid at 274. This is a proper little window of quality.
After that, the surf drops off into smaller, choppier conditions through the 17th and 18th with only ordinary surf, and then a few days of poor, cross-onshore junk from the 19th to the 20th. There’s a bigger spike of 7ft swell on the 21st of September from the ENE, but it’s cross-shore and messy, so it’s really only for the hardcore or the kite crew. The week ahead is a total blank until that Sunday the 13th, so just keep an eye on the sky and hope the forecasts hold.
Rusty.
