The Lowdown
G’day, Rusty here. Let’s break down what’s happening at Right and Left Side. The water’s sitting at about 86°, which is pretty normal for this time of year, so nothing unusual there.
The first real chance of any waves comes on the morning of Saturday, August 1st. We’ve got a 4ft easterly swell with a 14-second period – that’s a proper groundswell. The combined energy is 642, which is moderately strong. The wind is light and offshore from the northwest, so it’ll be glassy. But this spot is a reef, it’s inconsistent, and it really needs a north swell, not east. The swell is coming from the wrong direction, so the waves won’t shape up well. It’s a marginal call at best.
From Saturday afternoon onward, it’s a long stretch of poor conditions. The wind swings around to the west-southwest and blows 15 to 25 mph, cross-shore or cross-onshore, making everything choppy and lumpy. The swell hangs around 4ft to 5ft for a few days, but it’s messy with no decent shape.
Then from Wednesday, August 12th, into Thursday, August 13th, the swell jumps to 12ft to 15ft from the west. That’s huge, and the combined energy hits over 5000, which is very strong. But the wind is still howling from the west-southwest at 22 to 25 mph, cross-onshore. It’s a blown-out, dangerous mess that’s only for experts, and honestly, it looks more like a kite-surfing day than a paddle-surfing one.
So here’s the bottom line: there’s no standout session in this 16-day window. The only flicker of hope is Saturday morning, August 1st, and even that’s a gamble with the wrong swell direction. The rest is a blank run. It’s a tough stretch for this break, but forecasts can shift. Stay tuned.
Rusty.
