The Lowdown
G'day, I'm Rusty, and here's the lowdown on what's coming for our local stretch.
The first few days are the pick of the bunch. The standout is Johnsons (Noosa - Johnsons) starting Thursday morning the 20th. We've got a 6ft easterly swell with a 8-second period, and the wind is a cross-offshore ESE breeze, so the surface will be clean. The combined energy is moderate at 610, giving it some real punch. The water is sitting around 68°, which is a bit colder than usual for this time of year, so a wetsuit might be a good idea. That Thursday morning session is the one to aim for.
Friday morning the 21st is still clean with 4ft waves from the east and a light SE wind, but the energy is already fading. Saturday morning the 22nd drops to 3ft and glassy—it's tiny, but rideable on a longboard. From Saturday afternoon onwards, we hit a long stretch of small, messy surf. The wind goes onshore or cross, and the waves struggle to hit 3ft. There's a short window on Tuesday the 25th morning with glassy 3ft waves, but it's nothing special.
The second week stays quiet. The swell tries to pick up again around Monday the 31st of August with 6ft waves from the ENE, but it's cross-on with a moderate NNE breeze, making it choppy. It stays lumpy into early September. The best late hope is on Wednesday the 2nd of September afternoon with glassy 3ft waves, but it's still small. If you're after a long-range gamble, Thursday the 3rd of September morning has a 2ft easterly swell with a 10-second period and a light SSW offshore wind—clean, but tiny. Bottom line: get out early on Thursday the 20th morning for the best of it.
Rusty.
