The Lowdown
G’day, it’s Rusty here. Let’s be straight: the next couple of weeks are looking pretty flat and grim. There are no good surf options on the board for the full 16 days. The swell stays tiny, and the few bumps we get are mostly chopped up by wind or have no push behind them. The first week is a real drag, with nothing worth paddling out for. It’s not until around the 8th of September that the ocean finally wakes up a bit, but even then, it’s messy and not really surfable. It’s just wind chop over a weak, short-period swell. The tail end fades right back out again, leaving us high and dry.
For the first few days, we’ve got nothing. The swell is barely registering 0.3 to 1 foot, with a period of 4-9 seconds. The energy is basically non-existent. There’s some glassy early action on Saturday the 29th, but no wave to ride.
Heading into next week, there’s a slight bump on Monday the 31st, pushing to about 2 feet, but the period drops to a weak 4 seconds and the wind is cross-onshore. It’s junky. The energy starts to pick up a little by mid-week, but with such short-period slop and onshore winds, it’s not doing anyone any favours. Water temp is about average for the time of year.
The first real pulse of swell comes through on the 7th and 8th of September. We’re looking at a jump to 5-6 feet, with a big jump in energy. But here’s the kicker: the period is only 7 seconds. That’s just windswell, and it’s coming straight onshore. It’s going to be a messy, blown-out mess. That kind of size and short period isn’t great, and with this wind, it’s a washing machine. For beginners, that 5-foot plus is already too much. It’s more of a spectacle than a surf. After that, it fades away again quickly, dropping back to under 3 feet.
So, there we have it. A whole lot of nothing. If you’re desperate, you might get a bodysurf in on the 8th, but honestly, the setup looks more interesting for kite surfing than paddle surfing, especially with those strong cross-onshore winds around the 5th and 6th. It’s a blank run, and for this area, that’s how it goes sometimes. Hang tight, forecasts change, and it won’t stay flat forever.
Rusty.
