The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, the surf around here is going to be a tough sell. We’ve got a long stretch of flat, poor conditions ahead, so don’t go getting your hopes up for any proper sessions just yet.
The first sign of anything at all doesn’t even show up until the afternoon of Friday, the 28th of August. And even then, it’s barely a pulse. We’re talking about a dribbly 1ft of swell from the southwest, with a period of just 2 seconds. That’s not surf, that’s a ripple. The energy is basically non-existent at 1, and the wind is a moderate cross-shore, so it’ll be bumpy on top of being flat. It’s not worth paddling out for. Honestly, if you’re desperate, the setup at Zaga (Koroni) looks more interesting for a kite than a surfboard on days like that.
The weekend doesn’t offer any salvation either. Saturday the 29th sees another tiny 1ft southwest swell, again with a 2-second period and a combined energy of just 1. The morning is glassy, but the afternoon cross-off wind will keep it clean, just tiny. It’s still nothing to write home about.
We then hit another dead stretch. From Sunday the 30th of August all the way through Thursday the 3rd of September, there’s absolutely nothing on the cards. The ocean will be flat, just a glassy lake at times with some light breezes. You can leave the board in the car.
The next flicker of hope doesn’t come until Saturday, the 5th of September. The afternoon shows another 1ft swell, this time from the SSE. The period is again a weak 2 seconds, and the energy is a paltry 1. It’s a bit more aligned with what Zaga wants, but at this size, it’s still just a ripple. The gentle cross-off breeze will keep it clean, but there’s no power behind it.
That’s all we get. The entire 16-day window is a write-off for any real surfing. This break is listed as “rarely breaks” for a reason, and this forecast is a prime example. The water temp is a notable 83°F, which is 4°F warmer than normal for this time of year—that’s a big deal if you’re planning a swim, but it doesn't help the waves.
So, the long and short of it is: there are no good surf options in this window. Keep the board in the shed, save your energy, and hope the forecasts change. It can't stay this poor for long.
